CWHR Predicted Habitat Models represent areas of predicted suitable habitat for each species within its range. These models are built from the following principal inputs: 1) a statewide, best-available vegetation map (FVEG); 2) GIS data representing a species’ range; 3) the CWHR database of habitat suitability values for over 700 terrestrial vertebrate species. Habitat suitability ranks of Low (non-zero values less than 0.34), Medium (0.34-0.66), and High (greater than 0.66) are based on the maximum suitability value across the 3 species life requisites: reproduction, feeding, and cover. Note that previous versions of these Predicted Habitat Models used an average across the 3 life requisites in order to obtain an overall suitability score for each habitat type and stage class. Habitat suitability scores were developed based on habitat patch sizes greater than 40 acres in size and are best interpreted for habitat patches greater than 200 acres in size. The FVEG landcover dataset is an aggregation of multiple statewide landcover and regional vegetation mapping efforts, conducted at different points in time (approximately 1990 up to time of publishing) and at various resolutions, compiled by the California Department of Forestry and Fire Protection (CALFIRE). FVEG uses the most current and consistent data available for each region of the state. Decision rules were developed that controlled which layers were given priority in areas of overlap. Crosswalks were used to attribute the various data sources according to the CWHR habitat-type classification system. Attributing FVEG with CWHR habitat types allows for the extraction of areas with non-zero suitability values for each species within the bounds of its range, creating a series of maps of predicted suitable habitat which are species-specific. Because FVEG is an amalgam of disparate landcover assessment efforts across the state, the predictive power for determining suitable habitat will vary between species, and possibly even regionally for species which are widely distributed. While these maps represent CDFW’s best estimate of the presence of suitable habitat for any given species in the CWHR system, these maps are also limited by several factors: 1) the accuracy and resolution of vegetation maps in a given region; 2) the dynamic nature of the landscape in which fire and other disturbance events alter conditions at a greater frequency than mapping efforts can track; 3) the currency of expert knowledge, particularly as species adapt to changing land and climate conditions and the shifting of other species’ ranges; 4) the frequency of species-specific surveys across a representative sample of a species’ entire range; 5) metapopulation dynamics, which describes the shifting of populations within their environment as result of numerous types of interactions and responses. CWHR GIS data representing predicted suitable habitat should not be used to indicate the presence or absence of a particular species at any specific site. CWHR predicted habitat models are named according to the 4-character alpha-numeric CWHR ID assigned to each species (5 characters in the case of subspecies or other sub-taxa). There is also a “CWHR Revision Tracking Table” containing a record for each species, its CWHR ID, scientific name, common name, and range and habitat model data revision history. CWHR species range models, predicted habitat models, and GIS data of the statewide distribution of all CWHR habitat types, along with the CWHR revision tracking table, are available for download at https://www.wildlife.ca.gov/Data/CWHR.

This map includes change areas for city and county boundaries filed in accordance with Government Code 54900. The initial dataset was first published on October 20, 2021, and was based on the State Board of Equalization's tax rate area boundaries. As of April 1, 2024, the maintenance of this dataset is provided by the California Department of Tax and Fee Administration for the purpose of determining sales and use tax jurisdictions. The boundaries are continuously being revised when areas of conflict are discovered between the original boundary provided by the California State Board of Equalization and the boundary made publicly available by local, state, and federal government. Some differences may occur between actual recorded boundaries and the boundaries used for sales and use tax purposes. The boundaries in this map are representations of taxing jurisdictions and should not be used to determine precise city or county boundary line locations. The data is updated within 10 business days of the CDTFA receiving a copy of the Board of Equalization's acknowledgement letter. BOE_CityAnx Data Dictionary: COFILE = county number - assessment roll year - file number (see note*); CHANGE = affected city, unincorporated county, or boundary correction; EFFECTIVE = date the change was effective by resolution or ordinance (see note*); RECEIVED = date the change was received at the BOE; ACKNOWLEDGED = date the BOE accepted the filing for inclusion into the tax rate area system; NOTES = additional clarifying information about the action. *Note: A COFILE number ending in "000" is a boundary correction and the effective date used is the date the map was corrected. BOE_CityCounty Data Dictionary: COUNTY = county name; CITY = city name or unincorporated territory; COPRI = county number followed by the 3-digit city primary number used in the Board of Equalization's 6-digit tax rate area numbering system (for the purpose of this map, unincorporated areas are assigned 000 to indicate that the area is not within a city).

This dataset contains annual validated water loss audit reports submitted to the Department of Water Resources by California urban retail water suppliers, as required under Title 23, California Code of Regulations Section 638.5(c) (Regulation). California Water Code Section 10608.12(af) specifies that urban retail water suppliers are those water suppliers directly providing potable municipal water to more than 3,000 service connections or that supply more than 3,000 acre-feet per year at retail for municipal purposes. The Regulation mandates that urban retail water suppliers with multiple separate potable water systems submit a separate audit for each system, regardless of system size. The dataset includes individual water loss audits for all potable water systems owned by urban retail water suppliers, including reports from water suppliers newly classified as urban retail water suppliers. While all submissions are available at the WUEdata.ca.gov portal, this dataset provides a cleaned version with only the latest submissions (older submissions that were corrected are not included). Water system boundaries for the water system water loss data in this dataset may be available in the Water Board's DDW California Drinking Water System Area Boundaries (SABL) tool. The link to this tool can be found in Additional Resources as part of this dataset. Water loss audits evaluate real water losses (leaks) and apparent water losses (e.g. data errors, water theft) occurring in a potable water distribution system. Estimating the scale and cost of these losses allows utilities to identify opportunities for saving water and recovering revenue. California water loss audit submissions were reviewed by validators and submitted to DWR starting in 2016. The reviews followed the validation methodology detailed in Water Research Foundation Project 4639: Level 1 Water Audit Validation. Level 1 water audit validation aims to: * Identify and, where possible, correct inaccuracies in water audit data and application of methodology. * Evaluate and communicate the uncertainty inherent in water audit data. The data is provided "as is" (as submitted by the water systems). More information on this dataset can be found in the file "Data Source and Notes" available at the on the home page of this dataset.

The Current Employment Statistics (CES) program is a Federal-State cooperative effort in which monthly surveys are conducted to provide estimates of employment, hours, and earnings based on payroll records of business establishments. The CES survey is based on approximately 119,000 businesses and government agencies representing approximately 629,000 individual worksites throughout the United States. CES data reflect the number of nonfarm, payroll jobs. It includes the total number of persons on establishment payrolls, employed full- or part-time, who received pay (whether they worked or not) for any part of the pay period that includes the 12th day of the month. Temporary and intermittent employees are included, as are any employees who are on paid sick leave or on paid holiday. Persons on the payroll of more than one establishment are counted in each establishment. CES data excludes proprietors, self-employed, unpaid family or volunteer workers, farm workers, and household workers. Government employment covers only civilian employees; it excludes uniformed members of the armed services. The Bureau of Labor Statistics (BLS) of the U.S. Department of Labor is responsible for the concepts, definitions, technical procedures, validation, and publication of the estimates that State workforce agencies prepare under agreement with BLS.

The Reference table maintained by DHCS, displays aid code categories by aid code. Aid codes identify the criteria by which each person qualifies for Medi-Cal and the types of services he or she receives and make clear whether the services are funded by the State or Federal government or both. An aid code is a combination of two numbers or a letter and a number and is attached to a Medi-Cal beneficiary's identification numbers. Aid code category refers to a unique grouping of distinct aid codes into broad categories such as CHIP, Seniors and Persons with Disabilities, and Long-Term Care. For a description of each aid code, see [Medi-Cal Aid Code Master Chart](https://www.dhcs.ca.gov/wp-content/uploads/2025/12/2026-Master-Aid-Code-Chart.pdf).

The Groundwater Sustainability Plan (GSP) Monitoring dataset contains the monitoring sites and associated groundwater level, subsidence or streamflow measurements collected by Groundwater Sustainability Agencies (GSA) during implementation of their GSP. All data is submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM). The GSP Regulations established the monitoring network criteria (23 CCR § 354.34) and the data and reporting standard for monitoring sites and measurements (23 CCR § 352.4). The data fields associated with these datasets were created by DWR to ensure that GSAs electronically submit monitoring site and measurement data which meets the GSP Regulation’s data and reporting standards. For additional information regarding GSAs, GSPs, and SGMA related monitoring, please view DWR’s SGMA Portal Resources at https://sgma.water.ca.gov/portal/.

Data were extracted on measles cases with an estimated rash onset or episode date from January 1, 2026 through the last week indicated, from California Confidential Morbidity Reports and/or Laboratory Reports that were submitted to CDPH and which met the surveillance case definition for that disease. If the rash onset was unknown, the earliest available date from the following was used as episode date: symptom onset, diagnosis, laboratory specimen collection, reported to public health. Because of inherent delays in case reporting and depending on the length of follow-up of clinical, laboratory and epidemiologic investigation, cases with eligible onset dates may be added or rescinded after the date of this report.

In California, water systems serving one (1) to 15 households are regulated at the county level. Counties vary in their practices, but rarely do counties collect data regularly from these systems. Even where data is collected, it is entirely voluntary. A review of well permit information suggests there are over 1 million such water systems in California. In early 2014, a cross-agency Work Group created an easily accessible reporting system to get more systematic data on which parts of the state had households at risk of water supply shortages. The initial motivation for local water supply systems to report shortage information was to obtain statewide drought assistance. The reporting system receives ongoing reports of shortages from local, state, federal and non-governmental organizations, and tracks their status to resolution. While several counties have developed their own tracking mechanisms, this data is manually entered into the reporting system. The cross-agency team, led by DWR, seeks to verify and update the data submitted. However, due to the volunteer nature of the reporting and limitations on reporting agencies, collected data are undoubtedly under-representative of all shortages to have occurred. In addition, reports are received from multiple sources and there are occasionally errors and omissions that can create duplicate entries, non-household water supply reporting, and under-reporting. For example, missing information or no data for a given county does not necessarily mean that there are no household water shortages in the county, rather only that none have been reported to the State.
The Dry Well Reporting System is for use by individuals not served by a public water system experiencing problems with their water supply and agencies receiving calls from those individuals. How is this information going to be used? This information is intended to inform state and local agencies on drought impacts on household water supplies. The Household Water Supply Shortage Reporting System was first created as part of our emergency response efforts to previous droughts, and we are continuing to gather information relating to shortages of household water from private well or surface water sources. Collection of data is not to be construed as application for local, state or federal assistance. Individuals interested in financial assistance will be directed towards appropriate resources. Data Collection Entails: - Contact information for Household experiencing water shortage - Water Shortage Problem Information and Location - Financial Resources Available - Well Log Data (optional) - Reporting Agency or Local Government Information

California requires that all local governments (cities and counties) adequately plan to meet the housing needs of everyone in the community. California’s local governments meet this requirement by adopting housing plans as part of their “general plan”. General plans serve as the local government’s "blueprint" for how the city and/or county will grow and develop and include eight elements: land use, transportation, conservation, noise, open space, safety, environmental justice, and housing. The Housing Element Compliance Report provides current Housing Element Compliance Status. Additional information about Housing Elements can be found on HCD’s website here: https://www.hcd.ca.gov/planning-and-community-development/housing-elements.

*Back to [Basin Characterization Program webpage](https://data.cnra.ca.gov/dataset/dwr-basin-characterization "Basin Characterization Program webpage")* #Statewide AEM Surveys Project Overview The Department of Water Resources’ (DWR’s) Statewide Airborne Electromagnetic (AEM) Surveys Project is funded through California’s Proposition 68 and the General Fund. The goal of the project is to improve the understanding of groundwater aquifer structure to support the state and local goal of sustainable groundwater management and the implementation of the Sustainable Groundwater Management Act (SGMA). During an AEM survey, a helicopter tows electronic equipment that sends signals into the ground which bounce back. The data collected are used to create continuous images showing the distribution of electrical resistivity values of the subsurface materials that can be interpreted for lithologic properties. The resulting information will provide a standardized, statewide dataset that improves the understanding of large-scale aquifer structures and supports the development or refinement of hydrogeologic conceptual models and can help identify areas for recharging groundwater. DWR collected AEM data in all of California’s high- and medium-priority groundwater basins, where data collection is feasible. Data were collected in a coarsely spaced grid, with a line spacing of approximately 2-miles by 8-miles. AEM data collection started in 2021 and was completed in 2023. Additional information about the project can be found on the [Statewide AEM Survey website](https://water.ca.gov/Programs/SGMA/AEM "Statewide AEM Survey website"). See the publication below for an overview of the project and a preliminary analysis of the AEM data. DWR continues to collect data and has developed tools to utilize the Statewide AEM Survey data under the [Basin Characterization Program](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "Basin Characterization Program").

#Supporting Data An important part of the AEM data processing, inversion, and interpretation is the integration of existing supporting data. Supporting data utilized in the Statewide AEM Survey Project include well lithology, geophysical (electrical resistivity) logs, water level measurements, and water quality measurements. Data were compiled from groundwater sustainability agencies, counties, the Online System for Well Completion Reports (OSWCR), the California Geologic Energy Management (CalGEM) Well Finder, the Groundwater Ambient Monitoring and Assessment (GAMA), the California Statewide Groundwater Elevation Monitoring (CASGEM), and the United States Geologic Survey. Additional geophysical logs were purchased from a private company. Data compiled were screened to select high quality wells (described in the sections below). High quality wells were digitized and are provided in the Survey Area’s Supporting Data zip file, linked below: Survey Area 1: https://data.cnra.ca.gov/dataset/aem/resource/1f5509ec-6d57-4da4-8e7a-660d4c94efcd Survey Area 2: https://data.cnra.ca.gov/dataset/aem/resource/1f2275fb-e001-45b9-9749-3d3a216ab7ef Survey Area 3: https://data.cnra.ca.gov/dataset/aem/resource/8d405643-cb7f-4c3d-9333-736eeeb6ffd4 Survey Area 4: https://data.cnra.ca.gov/dataset/aem/resource/eb09227e-32c7-4e11-94f5-359c9b202734 Survey Area 5: https://data.cnra.ca.gov/dataset/aem/resource/366d53c0-6387-42d3-a39f-68aed6291853 Survey Area 6: https://data.cnra.ca.gov/dataset/aem/resource/e40fa03b-f62d-443d-a290-672405c0a3a4 Survey Area 7: https://data.cnra.ca.gov/dataset/aem/resource/ac9ed1fe-1487-4d31-a88b-361a8d584706 Survey Area 8: https://data.cnra.ca.gov/dataset/aem/resource/8c59ee43-1ad0-4860-9746-a4815330aed6 Survey Area 9: https://data.cnra.ca.gov/dataset/aem/resource/1e4bd143-63ec-4c5c-80ed-5dcf07ad1234 Survey Area 10: https://data.cnra.ca.gov/dataset/aem/resource/cfd1b037-cc3d-45d3-a519-38f4a5c37a0d Survey Area 11: https://data.cnra.ca.gov/dataset/aem/resource/262026e3-7a58-4e7b-ab77-4cba5b0ad7cf ##Well Lithology and Geophysical Logs ###High Quality Well lithology and geophysical logs located in the vicinity of the Survey Area were compiled with the objective of obtaining two high-quality logs in each of the Public Land Survey System (PLSS) one-mile square sections that the flight lines cross. High-quality lithology logs were defined as having a verified location accuracy of less than 50 meters (164 feet) and having an average lithology description interval of less than 30 meters (98 feet). High-quality well lithology logs were digitized and tabulated by transcribing the original lithology descriptions and categorized into the free-form, the Unified Soils Classification System (USCS), and texture descriptions. High-quality geophysical logs were defined as being less than 40 years old and having an image quality that could be digitized. Digitized geophysical logs are provided as .las files. ###Low Quality Well lithology and geophysical logs that were not within a one-mile square PLSS section that the flight lines cross or did not meet the high-quality criteria, were categorized as low-quality. Low quality wells were not digitized and are shown to provide the locations where lithology and geophysical logs were considered. ##Limitations Data are provisional. Map is under development. ###Integration of Supporting Data into Existing Databases The Supporting Data Map was developed for the purposes of displaying data compiled as a part of the Statewide AEM Survey Project. Digitized or refined data will be imported back into their original existing databases, like OSWCR or CalGEM.

The Occupational Employment and Wage Statistics (OEWS) Survey is a federal-state cooperative program between the Bureau of Labor Statistics (BLS) and State Workforce Agencies (SWAs). The BLS provides the procedures and technical support, draws the sample, and produces the survey materials, while the SWAs collect the data. SWAs from all fifty states, plus the District of Columbia, Puerto Rico, Guam, and the Virgin Islands participate in the survey. Occupational employment and wage rate estimates at the national level are produced by BLS using data from the fifty states and the District of Columbia. Employers who respond to states' requests to participate in the OEWS survey make these estimates possible. The OEWS survey collects data from a sample of establishments and calculates employment and wage estimates by occupation, industry, and geographic area. The semiannual survey covers all non-farm industries. Data are collected by the Employment Development Department in cooperation with the Bureau of Labor Statistics, US Department of Labor. The OEWS Program estimates employment and wages for approximately 830 occupations. It also produces employment and wage estimates for statewide, Metropolitan Statistical Areas (MSAs), and Balance of State areas. Estimates are a snapshot in time and should not be used as a time series. The OEWS estimates are published annually. __SOURCE: https://www.bls.gov/oes/oes_emp.htm__

White-Faced Ibis Predicted Habitat - CWHR B062 [ds2047]
This dataset contains fecal indicator bacteria (FIB) monitoring results collected from surface waters across California. It includes results for _Escherichia coli_ (E. coli), enterococci, fecal coliforms, and total coliforms - key indicators used to assess microbial water quality and potential health risks associated with recreational water use. The data has been cleaned and standardized to ensure consistency and usability. For each valid data point, the dataset also includes calculated 6-week and 30-day geometric means, which are commonly used to evaluate long-term water quality trends and compliance with bacteria water quality objectives. Some records are excluded from the final dataset during processing. These typically include duplicate or replicate results, records with missing or invalid result values, or any data that cannot be used to calculate a geometric mean. These records are saved to the "Excluded Records" data resource. This dataset serves as the primary data source for the Water Boards My Water Quality Portal [Safe to Swim Map](https://mywaterquality.ca.gov/safe-to-swim/content/interactive_map/index.html), which provides the public with timely information about potential health risks associated with water contact recreation at monitored sites. Data is sourced from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN) database, BeachWatch database, and the Central Valley Water Board [Lower American River Recreational Water Quality Map](https://experience.arcgis.com/experience/47e27f245e044ac2a8e15083307e75f6/?draft=true&org=waterboards). There is some overlap with the [CEDEN Water Chemistry dataset](https://data.ca.gov/dataset/surface-water-chemistry-results). Both portal datasets draw from the same source, but the resources here are updated more frequently to support the Safe to Swim map.

This resource includes a brief fact sheet describing DWR's [Dry Domestic Well Susceptibility Analysis](https://data.cnra.ca.gov/dataset/calgw-live/resource/e0bf3d2b-ceca-41ca-876f-d3e378503583) and [Dry Well Reporting System](https://mydrywell.water.ca.gov). DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the Dry Domestic Well Susceptibility within Groundwater Basins Dashboard (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation.
Dry Domestic Well Susceptibility and Reporting Fact Sheet
Seasonal groundwater level reports provide information from selected water level measurements and are intended to portray the change in seasonal groundwater levels over specific time intervals. Each point shows the calculated difference between the measured groundwater levels from the selected time periods. The change in groundwater level is plotted on the map only if a measurement exists in both time periods at a well. These change values are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. Data from the Periodic Groundwater Levels dataset is queried and categorized into seasons for each year, where "Spring" includes measurements occurring January through May, and "Fall" includes measurements occurring September through November. Measurements are excluded if they had quality codes indicating active pumping or flowing conditions, oil or foreign substances, or other quality issues. Of the Spring measurements for each well, the maximum groundwater level is taken to represent the seasonal high groundwater level. For Fall, the minimum groundwater level measurement for each well is taken to represent the seasonal low groundwater level. For Spring, the differences between the recent Spring maximum and the past Spring maximums (1, 3, 5, or 10 years ago) are shown in the WSE_CHANGE field. For Fall, the difference between the recent Fall minimum and the past Fall minimums are shown in the WSE_CHANGE field. The data is then classified into five categories in the WSE_CHANGE_CATEGORY field: decrease more than 25ft, decrease 5-25ft, no significant change (-5ft and +5ft), increase 5 25ft, increase more than 25ft. DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data.
Seasonal Groundwater Level Changes 1, 3, 5 and 10-Year (GIS Feature Service)
Groundwater levels at selected wells were analyzed using the Mann-Kendall non-parametric test to determine whether a statistically significant trend (declining trend, no trend, or increasing trends in groundwater levels) was present during the specified time period. To ensure sufficient data quality and temporal coverage, each well included in the analysis must meet minimum data requirements: at least 10 unique years of spring measurements, and those spring measurements must span at least 15 years within the 20-year period. When more than one spring measurement was available for a year, the highest (shallowest) water level was selected to represent that year. If a statistically significant trend was observed, the Thiel-Sen method was used to calculate the estimated slope of the trend line to quantify the decline or increase. These trends are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily.

Dry Well Reporting (GIS Feature Service)
DWR, in coordination with the State Water Resources Control Board, has developed an interactive dashboard, called the [Dry Domestic Well Susceptibility within Groundwater Basins Dashboard](https://storymaps.arcgis.com/stories/f2b252d15a0d4e49887ba94ac17cc4bb#ref-n-aoS5Sy) (Dry Well Susceptibility Dashboard), to identify areas within groundwater basins throughout the State that may be prone to water supply shortages due to domestic drinking water wells going dry. The dashboard identifies the density of "susceptible” domestic wells per square mile based on recent groundwater level measurements and modeled future depth to water. If the modeled future depth to water falls below the dry well depth of a domestic well, the well is labelled susceptible. The Dry Well Susceptibility Dashboard is housed on the California’s Groundwater Live web-based platform which contains the latest information and data on groundwater conditions across the State. The State, local agencies, and well owners can use this dashboard to anticipate where wells may be susceptible to inform drought preparedness decision-making and resource allocation. __If you are currently experiencing a dry domestic well, you can report that to DWR’s [Dry Well Reporting System](www.mydrywell.ca.gov) which will connect you with available local assistance.__ The query for domestic wells was based on DWR’s Online System for Well Completion Reports (OSWCR). Well uses that are specified on well completion reports have been grouped into domestic wells (See attribute 'B118WellUse'). The complete Well Completion Report Dataset is available at https://data.cnra.ca.gov/dataset/well-completion-reports. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of ongoing enhancements to CalGW Live. Once the format is finalized, the service will be hosted at https://gis.water.ca.gov/arcgis/rest/services/. _DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data._ _This dashboard and the underlying analysis provide a density map of domestic wells that are susceptible to going dry if recent groundwater trends continue. The map can be used to evaluate the relative density distribution within groundwater basins. However, the map should not be used to estimate the absolute number of domestic wells that are susceptible to going dry for any area or groundwater level scenario. While the applied groundwater level scenario is based on best available datasets, the scenario is hypothetical, and is chosen to resolve regional differences in the density of domestic wells that are susceptible to going dry. Available groundwater level data are interpolated and projected to domestic wells locations. To achieve near statewide coverage for this analysis, groundwater level measurements are projected up to 10 miles in areas where no local monitoring exists. Filling these groundwater level data gaps with new monitoring stations will improve the reliability of the Dry Well Susceptibility Analysis. The applied model for the depth at which a domestic well is susceptible to going dry is simplified and uncalibrated and is not intended to represent any specific well failure mode. Future calibration of this model, and consideration of well construction details will improve the reliability of the Dry Well Susceptibility Analysis._

The DWR Groundwater Level Percentile Statistics are based on the USGS Groundwater Watch concept of comparing the most recent groundwater level measurement to historical measurements for the same month. For a well to be ranked, the most recent measurement must have occurred within the last 18 months, and measurements from at least 10 years must exist for that month. These statistics are derived from the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. This dataset is maintained primarily in the DWR Enterprise Water Management database. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. Groundwater level percentile class information is determined by comparing a single measurement to all other measurements collected in the same month at that well. The “percentile class” is a statistical determination that describes the percentage of all measurements that are below a specific measurement. If 90 percent of measurements are below (deeper) than a given measurement, then it is in the 90th percentile and if only 10 percent of measurements are below, then that measurement is in the 10th percentile. An average measurement is the 50th percentile. The Fall 2022 and Spring 2024 measurement is classified into one of eight percentile categories, or statistical bins, based on all measurements for that well. These categories are: Lowest on Record, lowest 10% (Much Below Normal), 10-25% (Below Normal), 25-50% (Normal), 50-75% (Normal), 75-90% (Above Normal), highest 90% (Much Above Normal), and Highest on Record. The Groundwater Level Percentile Statistics are used for the Current Groundwater Level Conditions Dashboard, available at https://storymaps.arcgis.com/stories/b3886b33b49c4fa8adf2ae8bdd8f16c3#ref-n-uWnp7G DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data.

Points representing monitoring wells in DWR's groundwater elevation database which have a groundwater elevation measurement reported in the last 18 months. Information on the most recent measurement is included. This information is based on the DWR Periodic Groundwater Levels dataset that contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Monitoring at active sites is typically done manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. The field LAST_GSE_GWE represents the depth to groundwater and is calculated by subtracting the groundwater elevation (LAST_GWE) from the ground surface elevation (LAST_WLM_GSE). The Depth to Groundwater is then categorized into five bins for symbolization on the Current Groundwater Levels Dashboard. Those bins and their labels are: 0 ft through 25 ft (denoted as "25" in the attribute table), greater than 25 ft through 100 ft ("100"), greater than 100 ft through 200 ft ("200"), greater than 200 ft through 500 ft ("500"), and greater than 500 ft ("9999").

The complete Well Completion Report Dataset is available at https://data.cnra.ca.gov/dataset/well-completion-reports. The complete DWR Periodic Groundwater Levels dataset is available at https://data.cnra.ca.gov/dataset/periodic-groundwater-level-measurements. This service is under development as part of ongoing enhancements to CalGW Live. _DWR makes no warranties or guarantees — either expressed or implied — as to the completeness, accuracy, or correctness of the data. DWR neither accepts nor assumes liability arising from or for any incorrect, incomplete, or misleading subject data._ _This dashboard and the underlying analysis provide a density map of domestic wells that are susceptible to going dry if recent groundwater trends continue. The map can be used to evaluate the relative density distribution within groundwater basins. However, the map should not be used to estimate the absolute number of domestic wells that are susceptible to going dry for any area or groundwater level scenario. While the applied groundwater level scenario is based on best available datasets, the scenario is hypothetical, and is chosen to resolve regional differences in the density of domestic wells that are susceptible to going dry. Available groundwater level data are interpolated and projected to domestic wells locations. To achieve near statewide coverage for this analysis, groundwater level measurements are projected up to 10 miles in areas where no local monitoring exists. Filling these groundwater level data gaps with new monitoring stations will improve the reliability of the Dry Well Susceptibility Analysis. The applied model for the depth at which a domestic well is susceptible to going dry is simplified and uncalibrated and is not intended to represent any specific well failure mode. Future calibration of this model, and consideration of well construction details will improve the reliability of the Dry Well Susceptibility Analysis._

Government Code section 65400 requires that each city, county, or city and county, including charter cities, prepare an annual progress report (APR) on the status of the housing element of its general plan and progress in its implementation. This dataset includes information reported to the Department of Housing and Community Development (HCD) by local jurisdictions on their APR form. Additional information about annual progress reports (APR), including the form, instructions, and definition can be found on HCD’s website here: https://www.hcd.ca.gov/planning-and-community-development/annual-progress-reports.
Housing Element Annual Progress Report (APR) Data by Jurisdiction and Year
For up to 25 percent of a jurisdiction’s moderate-income regional housing need allocation, the planning agency may include the number of units in an existing multifamily building that were converted to deed-restricted rental housing for moderate-income households by the imposition of affordability covenants and restrictions for the unit. Before adding information to this table, jurisdictions must ensure housing developments meet the requirements described in Government Code 65400.2(b).
Local governments are required to inform HCD about any local tenant preference ordinance the local government maintains when the jurisdiction submits their annual progress report on housing approvals and production, per Government Code 7061 (SB 649, 2022, Cortese). Effective January 1, 2023, local governments adopting a tenant preference are required to create a webpage on their internet website containing authorizing local ordinance and supporting materials, no more than 90 days after the ordinance becomes operational.
Groundwater quality data and related groundwater well information available on the page was queried from the GAMA Groundwater information system (**[GAMA GIS](https://gamagroundwater.waterboards.ca.gov/gama/datadownload)**). Data provided represent a collection of groundwater quality results from various federal, state, and local groundwater sources. Results have been filtered to only represent untreated sampling results for the purpose of characterizing ambient conditions. Data have been standardized across multiple data sets including chemical names and units. Standardization has not been performed for chemical result modifier and others (although we are working currently to standardize most fields). Chemicals that have been standardized are included in the data sets. Therefore, other chemicals have been analyzed for but are not included in GAMA downloads. Groundwater samples have been collected from well types including domestic, irrigation, monitoring, municipal. Wells that cannot accurately be attributed to a category are labeled as "water supply, other". For additional information regarding the GAMA GIS data system please reference our **[factsheet](https://www.waterboards.ca.gov/publications_forms/publications/factsheets/docs/gama_gis_factsheet.pdf)**.

The California Department of Public Health (CDPH) is coordinating with wastewater utilities, local health departments, academic researchers, and laboratories in California on wastewater surveillance for infectious disease pathogens of interest to public health (such as SARS-CoV-2, the virus causing COVID-19, influenza, respiratory syncytial virus (RSV), mpox, and norovirus). Data collected from this network of participants, called the California Surveillance of Wastewaters (Cal-SuWers) Network, are submitted to the U.S. Centers for Disease Control and Prevention (CDC) National Wastewater Surveillance System (NWSS). Collecting and analyzing wastewater samples for the presence of, and amount of (concentration), a specified pathogen target can help inform public health about circulation of that infectious disease within a community. Data from wastewater testing do not replace existing public health surveillance systems but complement them. While wastewater surveillance cannot determine the exact number of infected persons in the area being monitored, it can provide overall trends of pathogen concentration within that community. Please note that data included in the Cal-SuWers Network and available here originate from multiple programs and laboratories. Methodologies for producing wastewater data are not currently standardized, and analyses, comparisons, and aggregations should be done with caution. Wastewater is a complex environmental sample and inherent variability in measured concentrations is expected due to environmental variability, day-to-day differences in sewershed and population dynamics, differences in the amount of shedding between people and pathogens, and laboratory and sampling variability. Please see the CDPH Cal-SuWers, CDC NWSS, and CDC Public Health interpretation and Use of Wastewater Surveillance data webpages for more information. Historical wastewater data can be found [here](https://data.ca.gov/dataset/covid-19-wastewater-surveillance-data-california).

Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 12+ and age 5+ denominators have been uploaded as archived tables. Starting June 30, 2021, the dataset has been reconfigured so that all updates are appended to one dataset to make it easier for API and other interfaces. In addition, historical data has been extended back to January 5, 2021. This dataset shows full, partial, and at least 1 dose coverage rates by zip code tabulation area (ZCTA) for the state of California. Data sources include the California Immunization Registry and the American Community Survey’s 2015-2019 5-Year data. This is the data table for the [LHJ Vaccine Equity Performance dashboard](https://public.tableau.com/profile/ca.open.data#!/vizhome/LHJVaccineEquityPerformance/MapView?publish=yes). However, this data table also includes ZTCAs that do not have a VEM score. This dataset also includes Vaccine Equity Metric score quartiles (when applicable), which combine the Public Health Alliance of Southern California’s Healthy Places Index (HPI) measure with CDPH-derived scores to estimate factors that impact health, like income, education, and access to health care. ZTCAs range from less healthy community conditions in Quartile 1 to more healthy community conditions in Quartile 4. The Vaccine Equity Metric is for weekly vaccination allocation and reporting purposes only. CDPH-derived quartiles should not be considered as indicative of the HPI score for these zip codes. CDPH-derived quartiles were assigned to zip codes excluded from the HPI score produced by the Public Health Alliance of Southern California due to concerns with statistical reliability and validity in populations smaller than 1,500 or where more than 50% of the population resides in a group setting. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. For some ZTCAs, vaccination coverage may exceed 100%. This may be a result of many people from outside the county coming to that ZTCA to get their vaccine and providers reporting the county of administration as the county of residence, and/or the DOF estimates of the population in that ZTCA are too low. Please note that population numbers provided by DOF are projections and so may not be accurate, especially given unprecedented shifts in population as a result of the pandemic.

Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a Structural Performance Category (SPC) which measures the probable seismic performance of building structural systems. Building structural systems include beams, columns, shear walls, slabs, and foundations. SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by January 1, 2020, unless an approved extension has been granted, and all SPC 2 buildings to be removed from providing general acute care services by January 1, 2030. A hospital facility meets the January 1, 2030 requirements if all the general acute care buildings on campus are SPC and NPC compliant. 2030 compliant SPC ratings are either SPC 3, 4, 4D, or 5. 2030 compliant NPC ratings is NPC 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.
Seismic Compliance Data By County for General Acute Care Hospitals

Data for seismic compliance in general acute care hospitals is grouped by counties. All general acute care hospital buildings are assigned a structural performance category (SPC). SPC ratings range from 1 to 5 with SPC 1 assigned to buildings that may be at risk of collapse during a strong earthquake and SPC 5 assigned to buildings reasonably capable of providing services to the public following a strong earthquake. State law requires all SPC 1 buildings to be removed from providing general acute care services by 2020 and all SPC 2 buildings to be removed from providing general acute care services by 2030. Therefore, a hospital facility that may be comprised of a number of hospital buildings meets the 2020 requirements if there are no SPC 1 buildings on campus. A hospital facility meets the 2030 requirements if all the buildings on campus are either SPC 3, 4 or 5. Data is provided for both hospital facilities and hospital buildings. Data is updated approximately every two weeks.

Freshwater harmful algal bloom (HAB) data from the Freshwater Harmful Algal Bloom (FHAB) data system. The FHAB data system is the California State Water Resources Control Board's data system for data and information voluntarily reported to the agency. Bloom reports are voluntary reports submitted by the public or organization to identify a POTENTIAL HAB for evaluation. Bloom Reports may or may not include a report that is confirmed to be a HAB, regardless, all bloom reports are published. Due to the voluntary basis of information and data included in the database, data and information may include: waterbody name and location, potential algal bloom location and observed characteristics, observed field observations and/or analytical sampling results, waterbody and/or land management, general information, recommended advisory status (if any), and updates regarding bloom status. Refer to Data Dictionary and Data Disclaimer for additional information about this dataset. Please visit the Water Boards FHABS web site for more information and data visualizations https://mywaterquality.ca.gov/habs/index.html.

Technical staff can add additional waterbody information.
DWR continuous groundwater level measurements contains continuous time-series data from automated recorders at sites operated by the Department of Water Resources. Readings are taken at 15-minute to one-hour intervals. Some of the readings are relayed to the California Data Exchange Center. However, most of the monitoring sites are visited once every month or two, when readings are off-loaded from data recorders, then finalized and published. Wells monitored for this dataset are located within Butte, Colusa, Glenn, Mendocino, Modoc, Sacramento, San Joaquin, Shasta, Siskiyou, Solano, Sutter, Tehama, Yolo, and Yuba Counties. Water-level measurements are the principal source of information about changes in groundwater storage and movement in a basin, and how these are affected by various forms of recharge (e.g., precipitation, seepage from streams, irrigation return) and discharge (e.g., seepage to streams, groundwater pumping). Water-level monitoring involves "continuous" or periodic measurements. Continuous monitoring makes use of automatic water-level sensing and recording instruments that are programmed to make scheduled measurements in wells. This provides a high-resolution record of water-level fluctuations. Resulting hydrographs can accurately identify the effects of various stresses on the aquifer system and provide measurements of maximum and minimum water levels in aquifers. Continuous monitoring may be the best technique to use for monitoring fluctuations in groundwater levels during droughts and other critical periods when hydraulic stresses may change at relatively rapid rates, or when real-time data are needed for making water management decisions [see usgs reference](https://ca.water.usgs.gov/sustainable-groundwater-management/groundwater-levels-california.html).

Hazardous waste identification (ID) numbers are issued by the U.S. Environmental Protection Agency (Federal EPA ID number) or by the Department of Toxic Substances Control (California State ID number). The ID number identifies each handler of hazardous waste on hazardous waste manifests and other paperwork. The ID number enables regulators to track the waste from its origin to final disposal, a process also referred to as “cradle to grave.” With a few exceptions, most hazardous waste generators must have an ID number before a registered hazardous waste transporter will accept their waste for shipment. All hazardous waste transporters and permitted treatment, storage, and disposal facilities (TSDFs) must have a hazardous waste ID number.

This dataset supports the [SWAMP Data Dashboard](https://gispublic.waterboards.ca.gov/swamp-data/), a public-facing tool developed by the [Surface Water Ambient Monitoring Program](https://www.waterboards.ca.gov/water_issues/programs/swamp/) (SWAMP) to provide accessible, user-friendly access to water quality monitoring data across California. The dashboard and its associated datasets are designed to help the public, researchers, and decision-makers explore and download monitoring data collected from California’s surface waters. This dataset includes five distinct resources: * __SWAMP Stations__ – Geospatial and descriptive information about SWAMP monitoring sites. * __Water Quality Results__ – Field and lab analysis results for chemical and physical parameters measured in water samples. * __Toxicity Summary Results__ – Summarized results from aquatic toxicity tests. Summary records are entries in the database that summarize the results from multiple replicate toxicity tests of the same sample water. * __Habitat Results__ – Data on physical habitat conditions typically collected alongside biological monitoring to provide context for interpreting water quality conditions. Includes scores for the California Stream Condition Index (CSCI) and Algal Stream Condition Index (ASCI). * __Tissue Summary Results__ – Annual summary statistics of contaminant concentrations in aquatic organism tissue samples. The data are derived from raw individual and composite tissue sample results. These data are collected by SWAMP and its partners to support water quality assessments, identify trends, and inform water resource management. The SWAMP Data Dashboard provides interactive visualizations and filtering tools to explore this data by region, parameter, and more. The SWAMP dataset is sourced from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN), which serves as the central repository for water quality data collected by various monitoring programs throughout the state. As such, there is some overlap between this dataset and the broader CEDEN datasets also published on the California Open Data Portal (see Related Resources). This SWAMP dataset represents a curated subset of CEDEN data, specifically tailored for use in the SWAMP Data Dashboard. Access the SWAMP Data Dashboard: https://gispublic.waterboards.ca.gov/swamp-data/ _*This dataset is provisional and subject to revision. It should not be used for regulatory purposes._

Surface water toxicity data from the [California Environmental Data Exchange Network](https://ceden.waterboards.ca.gov) (CEDEN). CEDEN is the California State Water Board's data system for surface water quality in California, and seeks to include all available statewide data (such as that produced by research and volunteer organizations). Data in CEDEN include field, sediment and water column data collected from freshwater, estuarine, and marine environments. Examples of data in CEDEN come from laboratory, physical and biological analyses and include data types associated with chemical, toxicological, field, bio-assessment, invertebrate, fish, and bacteriological assay assessments. The data resource "Surface Water Toxicity" contains two provisionally assigned values (“DataQuality” and “DataQualityIndicator”) to help users interpret the data quality metadata provided with the associated result. Zip files are provided for bulk data downloads (in csv or parquet file format), and developers can use the API associated with the "Surface Water Toxicity" (csv) resource to access the data. Users who want to manually download more specific subsets of the data can also use the [CEDEN Query Tool](https://ceden.waterboards.ca.gov/CQT/Home/AqtTool), which provides access to the same data presented here, but allows for interactive data filtering.

Monthly reports of water use and conservation activities by urban retail water suppliers, which are generally defined as agencies serving over 3,000 service connections or deliveries 3,000 acre-feet of water annually for municipal purposes. The most recent reporting period generally lags by about 2 months, due to the reporting deadline and the necessary subsequent dataset preparation. The full dataset that spans June 2014 to the most recent reporting period is the Per-Supplier Water Supply and Demand resource, which is an updated version of the dataset previously released on the Water Board's [Water Conservation Portal](https://www.waterboards.ca.gov/water_issues/programs/conservation_portal/conservation_reporting.html). Other datasets include the per-water-system supply and demand, representing a subset of the SAFER Clearinghouse dataset, and the conservation actions datasets. See the documentation PDF for data dictionaries and an explanation of the data flag methodology.

__Note__: In these datasets, a person is defined as up to date if they have received at least one dose of an updated COVID-19 vaccine. The Centers for Disease Control and Prevention (CDC) recommends that certain groups, including adults ages 65 years and older, receive additional doses. On 6/16/2023 CDPH replaced the booster measures with a new “Up to Date” measure based on CDC’s new recommendations, replacing the primary series, boosted, and bivalent booster metrics The definition of “primary series complete” has not changed and is based on previous recommendations that CDC has since simplified. A person cannot complete their primary series with a single dose of an updated vaccine. Whereas the booster measures were calculated using the eligible population as the denominator, the new up to date measure uses the total estimated population. Please note that the rates for some groups may change since the up to date measure is calculated differently than the previous booster and bivalent measures. This data is from the same source as the Vaccine Progress Dashboard at https://covid19.ca.gov/vaccination-progress-data/ which summarizes vaccination data at the county level by county of residence. Where county of residence was not reported in a vaccination record, the county of provider that vaccinated the resident is included. This applies to less than 1% of vaccination records. The sum of county-level vaccinations does not equal statewide total vaccinations due to out-of-state residents vaccinated in California. These data do not include doses administered by the following federal agencies who received vaccine allocated directly from CDC: Indian Health Service, Veterans Health Administration, Department of Defense, and the Federal Bureau of Prisons. Totals for the Vaccine Progress Dashboard and this dataset may not match, as the Dashboard totals doses by Report Date and this dataset totals doses by Administration Date. Dose numbers may also change for a particular Administration Date as data is updated. Previous updates: * On March 3, 2023, with the release of HPI 3.0 in 2022, the previous equity scores have been updated to reflect more recent community survey information. This change represents an improvement to the way CDPH monitors health equity by using the latest and most accurate community data available. The HPI uses a collection of data sources and indicators to calculate a measure of community conditions ranging from the most to the least healthy based on economic, housing, and environmental measures. * Starting on July 13, 2022, the denominator for calculating vaccine coverage has been changed from age 5+ to all ages to reflect new vaccine eligibility criteria. Previously the denominator was changed from age 16+ to age 12+ on May 18, 2021, then changed from age 12+ to age 5+ on November 10, 2021, to reflect previous changes in vaccine eligibility criteria. The previous datasets based on age 16+ and age 5+ denominators have been uploaded as archived tables. * Starting on May 29, 2021 the methodology for calculating on-hand inventory in the shipped/delivered/on-hand dataset has changed. Please see the accompanying data dictionary for details. In addition, this dataset is now down to the ZIP code level.

The Making Conservation a California Way of Life regulation requires urban retail water suppliers (URWS) to annually calculate their Urban Water Use Objective (UWUO), which is the sum of efficiency budgets for a subset of urban water uses: residential indoor water use, residential outdoor water use, real water loss and commercial, industrial and institutional landscapes with dedicated irrigation meters. Each efficiency budget will be calculated using a statewide efficiency standard and local service area characteristics such as population, climate, and landscape area. Where relevant, suppliers may also include in their objective “variances” for unique uses, or a bonus incentive for potable recycled water use. This dataset contains information gathered from reports submitted to the State Water Board, the Department of Water Resources, and other relevant information sources. It also contains information derived by the Board and the Department for the purpose of the regulation. The values in these tables are used to pre-fill a number of fields within the UWUO reporting form that URWS are required to submit by January 1 of each year, starting in 2025. To view the submitted values, please visit [this page](https://data.ca.gov/dataset/urban-water-use-objectives-compiled-report-data).
Urban Water Use Objectives – Relevant Data
Making Conservation a California Way of Life
This table is a compilation of the data submitted by urban retail water suppliers to the State Water Board via the Variance and Temporary Provisions Request Form. It tracks the dates of submission, approval statuses and approval dates for variances or temporary provisions.
Submissions and Approvals for Variances and Temporary Provisions
The Water Conservation Act of 2009 (Senate Bill X7-7) was enacted in November 2009 and required that all water suppliers increase their water use efficiency. Water Code section 10608.20 directed urban retail water suppliers (suppliers) to develop 2020 urban water use targets. This table contains the suppliers’ individual SB X7-7 targets. Because some suppliers deducted discrete demands from gross water use when calculating their 2020 urban water use targets, the table also contains the volume of those deducted demands, specifically for indirect recycled water and process water. Water Code section 10608.20(a)(1) and 10608.28 provided that suppliers may plan, comply, and report on a regional basis, individual basis, or both. Each group of water suppliers agreeing among themselves to plan, comply, and report as a region is referred to as a “regional alliance.” For those suppliers that took part in a regional alliance, this table also lists the regional alliance name and indicates whether the regional alliance has met its target. All data within this table were derived from the [2020 Urban Water Management Plans Open Data](https://data.ca.gov/dataset/2020-uwmp-data-export-tables), which were created using data submitted by suppliers to Department. Specifically, this table was created using the following fields: * Individual SB X7-7 target from Tab SB_X7-7_CF_Table_9, column K * Indirect recycled water volume from Tab SB_X7-7_CF_Table_4, column J * Process water volume from Tab SB_X7-7_CF_Table_4, column L * Recycled and process water units from Tab SB_X7-7_VF_Table_0, column F * Regional alliance name from Tab SB_X7-7_CF_Table_9 * Whether the regional alliance met its target Tab Regional_Alliance_Summary, column F As described in the [2020 Urban Water Management Guidebook](https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/Urban-Water-Use-Efficiency/Urban-Water-Management-Plans/Final-2020-UWMP-Guidebook/UWMP-Guidebook-2020---Final-032921.pdf)[(Appendix P.3.2)](https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Water-Use-And-Efficiency/Urban-Water-Use-Efficiency/Urban-Water-Management-Plans/Final-2020-UWMP-Guidebook/Appendix-P---UWMP-2020.pdf), a supplier’s target may be updated if its service area has changed because of a consolidation, merger, annexation, expansion, or contraction. To learn more about this process, please e-mail [uwmphelp@water.ca.gov](mailto:uwmphelp@water.ca.gov).
SB X7-7 Targets for Urban Retail Water Suppliers
Consistent with California Code of Regulations title 23 §980 through §986, urban retail water suppliers are required to comply with real water loss standards. This table contains the real water loss standards for public water systems owned and operated by urban retail water suppliers. The list of public water systems in this resource is based on the PWSID-DWRID crosswalk resource that is also a part of the [Urban Water Use Objectives dataset and the April 9, 2024 water loss standards](https://www.waterboards.ca.gov/conservation/water_loss_control.html). Consistent with §984 of the California Code of Regulations, default parameters in the economic model used to generate system-specific standards may be updated, upon supplier request. To submit a request for an update, please email [DDW-WaterLossControl@waterboards.ca.gov](mailto:DDW-WaterLossControl@waterboards.ca.gov).

This dataset is a draft crosswalk, indicating which public water systems are owned and operated by which urban retail water suppliers. “Urban retail water supplier” means a water supplier, either publicly or privately owned, that directly provides potable municipal water to more than 3,000 end users or that supplies more than 3,000 acre-feet of potable water annually at retail for municipal purposes. The Department of Water Resources has assigned each Urban Retail Water Suppliers a unique "Organization Identification." Urban Retail Water Suppliers in California operate one or more public water systems. A “public water system” means a system for the provision of water for human consumption through pipes or other constructed conveyances. The State Water Resources Control Board has assigned each public water system a unique "public water system identification." This dataset connects each Supplier's "Organization Identification" number to its "public water system identification" number or numbers. This is the second version of this dataset, and will be utilized for the FY2025-2026 UWUO report onwards, as well as updated versions of prior reports. It has better handling of consolidations and systems being added or removed from reporting. Systems identified in this crosswalk may not be relevant to the water loss or "Conservation as a Way of Life" regulations. Contact [orpp-waterconservation@waterboards.ca.gov](mailto:orpp-waterconservation@waterboards.ca.gov) for any questions or corrections to this crosswalk.

The Behavioral Health Public County Profile represents DHCS’s effort to consolidate key county behavioral health information into a consistent and accessible format, helping reduce fragmented data sources and improve transparency. This marks a significant step forward in modernizing and streamlining access to behavioral health data. The initial version of the Behavioral Health Public County Profile provides a high-level snapshot of key information, including –draft Integrated Plan status, county demographics, and homelessness and housing visualizations, as well as a quick reference guide within the display for the public to better understand the information being presented. Using standardized definitions and shared identifiers, the Behavioral Health Public County Profile data is comparable between counties and statewide and will be aligned in public reporting. The Behavioral Health Public County Profile visualizations will be continuously updated as new data sets and behavioral health reporting becomes available. DHCS is releasing the Behavioral Health County Profile in phases based on data availability and reporting timelines. The initial version includes the following sections: * Overview * Demographics (general population and Medi-Cal behavioral health) * Integrated Plan (draft submission status) * Homeless/Housing The Behavioral Health County Profile makes county behavioral health data comparable statewide and provides aligned public reporting. It provides a digestible snapshot of Integrated Plans, funding information, compliance status, and performance over time—and will be enhanced with additional data sets so DHCS and counties can work from the same facts at the same time. This marks an important step forward in behavioral health data access just two years after California voters passed the Behavioral Health Services Act (BHSA).
The Overview file provides a consolidated summary of a County Behavioral Health Departments contact information, County Population, Medi-Cal Managed Care Plans operating within a county, County Medi-Cal Enrollment, and previous County Behavioral Health Medi-Cal services.
Behavioral Health Public County Profile - Overview
The Integrated Plan file contains county‑level submission data associated with the new Behavioral Health Integrated Plans required under Proposition 1 and the Behavioral Health Services Act. These plans serve as each county’s comprehensive, prospective three‑year blueprint for local behavioral health service delivery, funding allocation, equity goals, and outcome expectations. County Integrated Plans outline how counties will structure and invest in mental health and substance use disorder services, including community planning, housing interventions, Medi‑Cal‑aligned service expansions, and workforce strategies.
Behavioral Health Public County Profile - Integrated Plan Status
The Homeless/Housing file provides county-level data on individuals at risk of or experiencing homelessness who interact with community housing services and public Behavioral Health delivery systems.
Behavioral Health Public County Profile - Homeless/Housing
The Demographics file provides county‑level demographic indicators used to support statewide behavioral health planning, program evaluation, and transformation efforts led by the California Department of Health Care Services (DHCS). This file consolidates demographic attributes from multiple state and federal sources such as Census data, Medi-Cal enrollment systems, and aggregated county submissions in order to provide a consistent view of the population characteristics related to behavioral health needs and service capacity across all 58 California counties.

DSM2 models, data, and other resources. The links are in chronological order, with most recent releases at the top. * The Delta Simulation Model II (DSM2) is a is a river, estuary, and land modeling system. It is a one-dimensional mathematical model for dynamic simulation of one-dimensional hydrodynamics, water quality and particle tracking in a network of riverine or estuarine channels. DSM2 can calculate stages, flows, velocities, mass transport processes for conservative and non-conservative constituents including salts, water temperature, dissolved oxygen, and trihalomethane formation potential, and transport of individual particles. DSM2 thus provides a powerful simulation package for analysis of complex hydrodynamic, water quality, and ecological conditions in riverine and estuarine systems. * DSM2 is licensed under the GNU General Public License.

Version "DSM2 Input 2026-04-16 historical update" is based on version "DSM2 Input 2025-09-18 historical update" (which incorporates the changes from the Monitoring Special Study version of DSM2), and includes the following changes: The CHANNEL input section in the file channel_std_delta_grid.inp has been modified to work with DSM2 v8.5.0, by including the "dx" field, which specifies a value of the parameter "delta x" separately for each channel. Previously, delta x values have been specified in a file called variable_dx.csv. This file has been removed. The location of the Middle River Barrier has been corrected by adding channel 901 to replace a portion of channel 134. The Middle River barrier has been placed on the upstream side of the node for consistency with the configurations of other barriers. Dispersion factors have been adjusted to improve EC results.

Borehole extensometers are a more site specific method of measuring land subsidence. These instruments consist of a pipe or cable anchored at the bottom of a well casing. Pipe or cable extend from the bottom of the well, through geologic layers susceptible to compaction, to the ground surface. The pipe or cable is connected to a recorder that measures the relative distance between the bottom of the bore hole to the ground surface. These instruments are capable of detecting changes in land surface elevation to 1/100th of a foot. When land subsidence and water depth monitoring activities are paired together, hydraulic and mechanical properties of the aquifer system can be determined. DWR monitors 11 extensometers in the Sacramento Valley. For more information regarding land subsidence monitoring vist: http://www.water.ca.gov/groundwater/landsubsidence/LSmonitoring.cfm

The DWR Periodic Groundwater Levels dataset contains seasonal and long-term groundwater level measurements collected by the Department of Water Resources and cooperating agencies in groundwater basins statewide. It also includes data collected through the Sustainable Groundwater Management Act (SGMA) Portal’s Monitoring Network Module (MNM), and the CASGEM (California Statewide Groundwater Elevation Monitoring) Program. Most measurements are taken manually twice per year to capture the peak high and low values in groundwater elevations. However, the dataset also includes measurements recorded more frequently, monthly, weekly, or daily. This resource also included daily measurements from DWR's automated monitoring network of groundwater sites. For DWRs holdings of groundwater level measurements recorded at more frequent intervals (e.g., hourly), please refer to DWR's “Continuous Groundwater Level Measurements” dataset. For additional information regarding DWR groundwater levels data collection please visit DWR's Groundwater Management website (https://www.water.ca.gov/Programs/Groundwater-Management). The source data can also be accessed directly from two websites. The Water Data Library (http://wdl.water.ca.gov) provides anonymous access to this and other data sets. The CASGEM online system (https://www.casgem.water.ca.gov/OSS) provides authenticated access to only the the periodic groundwater measurements. This dataset is maintained primarily in the DWR Enterprise Water Management database and contains information specific to the location of groundwater level monitoring wells and groundwater level measurements collected at these wells. The Stations resource identifies well location coordinates and other supplementary items about the well type. Measurements resources includes information about the time/date a measurement was collected, the entity collecting the measurement, a measurement indicating the depth to groundwater, and quality information about the measurement. The Well Perforations resources contains well construction information identifying the well's screened intervals (not available for all wells).

The Groundwater Sustainability Plan (GSP) Annual Report (AR) datasets contain the following data submitted by Groundwater Sustainability Agencies (GSA) and Alternative Agencies as part of their GSP AR or Alternative to GSP AR: groundwater extraction, surface water supply, total water use, and change in storage volumes for a given water year. All data was originally submitted to the Department of Water Resources (DWR) through the Sustainable Groundwater Management Act (SGMA) Portal’s AR Modules (https://sgma.water.ca.gov/portal/gspar/submitted and https://sgma.water.ca.gov/portal/alternative/annualreport/submitted). Data records within each dataset correspond to either an entire basin or one of multiple GSP areas which collectively correspond to an entire basin. The GSP Regulations established the AR data requirements (23 CCR § 356.2) and tasked DWR with developing an online reporting system for GSAs and Alternative Agencies to electronically submit these data (23 CCR § 353.2). The data fields associated with these datasets were created by DWR to ensure GSAs and Alternative Agencies electronically submitted the required AR data to DWR’s online reporting system, the SGMA Portal (https://sgma.water.ca.gov/portal/). For additional information regarding the AR Modules and the AR submittal process, please view the DWR’s AR resources (https://sgma.water.ca.gov/portal/resources).

This dataset contains positive cases of West Nile virus found in humans by county of residence, 2006-present. Humans usually become infected with West Nile virus by being bitten by an infected mosquito. Viruses carried in the mosquito’s saliva enter the blood stream and local tissues where they infect immune cells. Most of the people who do become sick during a WNV infection develop what is referred to as “West Nile fever.” A small percentage of people will develop a much more serious illness called West Nile neuroinvasive disease (WNND). Positive cases in this dataset include both West Nile fever and West Nile neuroinvasive disease.

The Division of Drinking Water (DDW) identifies Failing and At-Risk community water systems and K-12 non-transient, non-community schools. This information is displayed online in the Safe and Affordable Funding for Equity and Resilience (SAFER) Dashboard. The data utilized for this assessment is derived from multiple sources: self-reported from water systems, data generated by DDW staff, other California state agencies, and U.S. Census. The data sources, calculation methods, Failing and At-Risk criteria, etc. are fully documented in the annual Drinking Water Needs Assessment report which is published annually on the State Water Board’s website.
