Urban Water Use Objectives – Compiled Report Data
The Making Conservation a California Way of Life regulation requires urban retail water suppliers 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 the information submitted to the State Water Resources Control Board and the Department of Water Resources on the required reporting form. The values have been aggregated into individual tables that roughly correspond to the sections within the reporting form. The original submitted files can be found at the [WUE Data Portal](https://wuedata.water.ca.gov/uwuo_plans) To view the source data that pre-filled many of the fields within the reporting form, please visit [this page](https://data.ca.gov/dataset/urban-water-use-objectives-conservation).

The Grant Information Act requires state agencies to provide summaries of each of their grant or loan opportunities, including information about how to apply and links that grantseekers can follow for more details. *FYI* If you're not familiar with data.ca.gov, you can download the csv and find the API call by clicking on the "Explore" button below. *Note*: the data set updates every 24 hours at 8:45pm.
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. For more information, please go to https://dtsc.ca.gov/hazardous-waste-id-numbers/.

COVID-19 Vaccine Progress Dashboard Data
__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.
COVID-19 Vaccine Progress Dashboard Data by ZIP Code
__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. 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.
WDL Ground Surface Displacement - Land Subsidence Monitoring
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
Continuous Groundwater Level Measurements
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).
Groundwater Sustainability Plan Annual Report Data
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).

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) 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/.

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.
CDPH-Wastewater Surveillance Data, California
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).

Insurance Affordability Programs Eligibility Appeals Hearing Results
This dataset includes the hearing results for eligibility appeals filed for subsidized Covered California coverage, Medi-Cal, or a combination of both eligibility determinations by year and quarter. The Department of Health Care Services (DHCS) assigns responsibility for conducting fair hearing requests (appeals) to the California Department of Social Services (CDSS). CDSS receives appeal requests, conducts hearings through their statewide network of administrative law judges, and renders decisions. CDSS provides these services to DHCS through a contract called an interagency agreement. In addition to the interagency agreement, the Delegation Order gives an Administrative Law Judge the authority to review and adopt decisions for hearings. Hearing requests (appeals) may be filed for cases involving mixed determinations, such as when household members applied for and/or had eligibility determinations made for the two programs (i.e., parents were eligible for Covered California and the child(ren) were eligible for Medi-Cal). Hearings are held when an appeal filed by an appellant for determinations that resulted in a denial, eligibility, or discontinuance of coverage. This dataset provides categories of hearing results and includes granted, granted in part, denied, or withdrawn/dismissed. This dataset is part of the public reporting requirements set forth in the California Welfare and Institutions Code 14102.5(a)(6).

Appeals may be filed by an appellant for determinations that resulted in a denial, eligibility, or discontinuance of coverage. A denial is defined as an eligibility determination at application that resulted in a denial of coverage. An appeal regarding an eligibility determination may be filed when the appellant disputes the type of program eligibility. A discontinuance is when an individual is no longer eligible for Medi-Cal or Covered California QHP. Appeals may be filed for cases involving mixed determinations, such as when household members applied for and/or had eligibility determinations made for the two programs (i.e., parents were eligible for Covered California and the child(ren) were eligible for Medi-Cal). Covered California and Medi-Cal eligibility appeals are processed and adjudicated by Administrative Law Judges and the California Department of Social Services (CDSS) staff who track appeals and hearing results. This dataset is part of the public reporting requirements set forth in California Welfare and Institutions Code 14102.5(a)(6).

The California Department of Forestry and Fire Protection's Fire and Resource Assessment Program (FRAP) annually maintains and distributes an historical wildland fire perimeter dataset from across public and private lands in California. The GIS data is developed with the cooperation of the United States Forest Service Region 5, the Bureau of Land Management, California State Parks, National Park Service and the United States Fish and Wildlife Service and is released in the spring with added data from the previous calendar year. Although the dataset represents the most complete digital record of fire perimeters in California, it is still incomplete, and users should be cautious when drawing conclusions based on the data. This data should be used carefully for statistical analysis and reporting due to missing perimeters (see Use Limitation in metadata). Some fires are missing because historical records were lost or damaged, were too small for the minimum cutoffs, had inadequate documentation or have not yet been incorporated into the database. Other errors with the fire perimeter database include duplicate fires and over-generalization. Additionally, over-generalization, particularly with large old fires, may show unburned "islands" within the final perimeter as burned. Users of the fire perimeter database must exercise caution in application of the data. Careful use of the fire perimeter database will prevent users from drawing inaccurate or erroneous conclusions from the data. This data is updated annually in the spring with fire perimeters from the previous fire season. This dataset may differ in California compared to that available from the National Interagency Fire Center (NIFC) due to different requirements between the two datasets. The data covers fires back to 1878. As of May 2026, it represents firep25_1. Please help improve this dataset by filling out this survey with feedback: Historical Fire Perimeter Dataset Feedback Current criteria for data collection are as follows: CAL FIRE (including contract counties) submit perimeters ≥10 acres in timber, ≥50 acres in brush, or ≥300 acres in grass, and/or ≥3 impacted residential or commercial structures, and/or caused ≥1 fatality.

DWR has a long history of studying and characterizing California’s groundwater aquifers as a part of [California’s Groundwater (Bulletin 118)](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118 "California’s Groundwater (Bulletin 118)"). [California's Groundwater Basin Characterization Program](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "California's Groundwater Basin Characterization Program") provides the latest data and information about California’s groundwater basins to help local communities better understand their aquifer systems and support local and statewide groundwater management. Under the Basin Characterization Program, new and existing data (AEM, lithology logs, geophysical logs, etc.) are integrated to create continuous maps and three-dimensional models. To support this effort, new data analysis tools have been developed to create texture models, hydrostratigraphic models, and aquifer flow parameters. Data collection efforts have been expanded to include advanced geologic, hydrogeologic, and geophysical data collection and data digitization and quality control efforts will continue. To continue to support data access and data equity, the Basin Characterization Program has developed new online, GIS-based, visualization tools to serve as a central hub for accessing and exploring groundwater related data in California. More information is available on the [Basin Characterization Program webpage](https://water.ca.gov/Programs/Groundwater-Management/Bulletin-118/Basin-Characterization "Basin Characterization Program webpage"). --- # [Maps and Models](https://data.cnra.ca.gov/dataset/dwr-basin-characterization/resource/6b4823ed-e1e6-4a91-b1c6-f88423962f90 "Maps and Models") Integrated datasets are used to develop state‑stewarded maps and 3D models describing aquifer structure, sediment textures, hydrostratigraphy, and groundwater‑flow properties.

DWR Airborne Electromagnetic (AEM) Surveys Data
*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"). Visit the [Basin Characterization Program Open Data Portal page](https://data.cnra.ca.gov/dataset/dwr-basin-characterization "Basin Characterization Program Open Data Portal page") to access tools, datasets, and resulting maps and models. ## [California’s Statewide Airborne Electromagnetic Surveys and Preliminary Hydrogeologic Interpretations](https://www.conservation.ca.gov/cgs/documents/publications/california-geology-magazine/CG_2024-AEMsurveys.pdf "California’s Statewide Airborne Electromagnetic Surveys and Preliminary Hydrogeologic Interpretations") --- # Survey Areas AEM data are being collected in groups of groundwater basins, defined as a Survey Area.

This dataset represents measurements of vertical ground surface displacement in more than 200 of the high-use and populated groundwater basins across the State of California between January of 2015 and April of 2022. Vertical displacement estimates are derived from Interferometric Synthetic Aperture Radar (InSAR) data that are collected by the European Space Agency (ESA) Sentinel-1A satellite and processed by TRE ALTAMIRA Inc. (TRE), under contract with the California Department of Water Resources (DWR) as part of DWR’s SGMA technical assistance to provide important SGMA-relevant data to GSAs for GSP development and implementation. Sentinel-1A InSAR data coverage began in late 2014 for parts of California, and coverage for the entire study area began in June 13, 2015. Included in this dataset are point data that represent average vertical displacement values for 100 meter by 100 meter areas, as well as GIS rasters that were interpolated from the point data; rasters for total vertical displacement relative to June 13, 2015, and rasters for annual vertical displacement rates with earlier coverage for some areas, both in monthly time steps. Towill Inc. (Towill), also under contract with DWR as part of DWR’s SGMA technical assistance, conducted an independent study comparing the InSAR-based vertical displacement point time series data to data from Continuous Global Positioning System (CGPS) stations. The goal of this study was to ground-truth the InSAR results to best available independent data. Data update frequency: Quarterly Report update frequency: Annual
Urban Water Use Objectives – Relevant Data
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).

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) 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.

Marbled Murrelet Predicted Habitat - CWHR B240 [ds2165]
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.
Marbled Murrelet Range - CWHR B240 [ds930]
CWHR species range datasets represent the maximum current geographic extent of each species within California. Ranges were originally delineated at a scale of 1:5,000,000 by species-level experts more than 30 years ago and have gradually been revised at a scale of 1:1,000,000. Species occurrence data are used in defining species ranges, but range polygons may extend beyond the limits of extant occurrence data for a particular species. When drawing range boundaries, CDFW seeks to err on the side of commission rather than omission. This means that CDFW may include areas within a range based on expert knowledge or other available information, despite an absence of confirmed occurrences, which may be due to a lack of survey effort. The degree to which a range polygon is extended beyond occurrence data will vary among species, depending upon each species’ vagility, dispersal patterns, and other ecological and life history factors. The boundary line of a range polygon is drawn with consideration of these factors and is aligned with standardized boundaries including watersheds (NHD), ecoregions (USDA), or other ecologically meaningful delineations such as elevation contour lines. While CWHR ranges are meant to represent the current range, once an area has been designated as part of a species’ range in CWHR, it will remain part of the range even if there have been no documented occurrences within recent decades. An area is not removed from the range polygon unless experts indicate that it has not been occupied for a number of years after repeated surveys or is deemed no longer suitable and unlikely to be recolonized. It is important to note that range polygons typically contain areas in which a species is not expected to be found due to the patchy configuration of suitable habitat within a species’ range. In this regard, range polygons are coarse generalizations of where a species may be found. This data is available for download from the CDFW website: https://www.wildlife.ca.gov/Data/CWHR. The following data sources were collated for the purposes of range mapping and species habitat modeling by RADMAP. Each focal taxon’s location data was extracted (when applicable) from the following list of sources.

The information encoded about these features includes classification and other characteristics, delineation, geographic name, position and related measures, a "reach code" through which other information can be related to the NHD, and the direction of water flow. The network of reach codes delineating water and transported material flow allows users to trace movement in upstream and downstream directions. In addition to this geographic information, the dataset contains metadata that supports the exchange of future updates and improvements to the data. The NHD supports many applications, such as making maps, geocoding observations, flow modeling, data maintenance, and stewardship.

Upon completion, 3DHP data will be easier to maintain, based on a modern data model and architecture, and better meet the requirements of users that were documented in the Hydrography Requirements and Benefits Study (2016). The initial releases of 3DHP include NHD vector data incorporated into the 3DHP data model. As new elevation-derived hydrography is created for California, that geometry will replace the legacy NHD vectors in the 3DHP dataset.

Sierra Nevada Red Fox (Southern Cascades DPS) Range - CWHR M147d [ds3358]
The updated range map for Sierra Nevada red fox (Vulpes vulpes necator) was developed using multiple sources of information (see Figure 1 of Sierra Nevada Red Fox Species Habitat Model Metadata: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=245187). Using the historic range described in Grinnell et al. (1937) in The Mammals of California as a foundation, we refined the boundary using contemporary Sierra Nevada red fox occurrence records and habitat suitability modeling to describe the updated range (See Appendix 1 and 2 of Sierra Nevada Red Fox Species Habitat Model Metadata: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=245187).

The updated range map for North American wolverine (Gulo gulo) was developed using multiple sources of information (see Figure 1 of Wolverine Species Habitat Model Metadata: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=245204). Using the historic range described in Grinnell et al. (1937) in The Furbearer Mammals of California as a foundation, we refined the boundary using historic and contemporary wolverine occurrence records and habitat suitability modeling to describe the updated range (See Appendix 1 of Wolverine Species Habitat Model Metadata: https://nrm.dfg.ca.gov/FileHandler.ashx?DocumentID=245204). This range does not include likely long-distance migratory or dispersal areas and only represents the range that may be used as part of an established home range for this species.

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.
Vegetation - Fallbrook Naval Weapons Station [ds2958]
This mapping effort was conducted following the guidelines described in Vegetation Mapping Protocol for Naval Weapons Station Seal Beach Detachment Fallbrook ("Protocol"; USDON 2017). Four-band (color with color IR) aerial images were collected by GeoTerra, Inc. during June 20 and 21, 2015. All flight plans and airspace access were authorized through Marine Corps Base Camp Pendleton Range Control (Longrifle). All image acquisition, processing, and ortho-rectification were conducted by GeoTerra, Inc. Final orthophotos were delivered with a resolution of 0.25 foot. This set of images served as the visual layer for photo-interpretation. The classification was generated by AECOM. AECOM conducted vegetation sampling consistent with NVC Standard methods throughout NWSSB-DF to define the subset of alliances and associations that occurred within the mapping area. Further details, and the full classification, can be found in Vegetation Mapping Protocol for Naval Weapons Station Seal Beach Detachment Fallbrook ("Protocol"; USDON 2017). No thematic accuracy assessment was performed, however field verification was conducted to establish photo-signature training for each alliance and association. Approximately 37% (accounting for 67% of the total mapped area) of all polygons and vegetation assignments were field verified. A minimum mapping unit (MMU) of 0.25 hectare was used.

The depth slice intervals were defined by the Coarse Fraction data inversion geometry. The 1-15 meter depth interval was defined as the depth weighted average Coarse Fraction value over the defined interval. Coarse Fraction data for Survey Area 1 were averaged to match Survey Areas 2 through 7 data resolution. The accuracy of the depth slice values for Survey Area 1 are +/- 1 meter of the depth slice displayed.

Seismic Compliance Data By County for General Acute Care Hospitals (CSV)
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.

Digitized lithology and geophysical logging data for the Madera & North Kings Local Investigation. File updated 1/13/2026.
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. 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.

SB X7-7 Targets for Urban Retail Water Suppliers
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.

Currently, 84 WIC agencies provide services monthly to over 1.45 million participants at over 650 sites in local communities throughout the State.
#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.

Electrical Resistivity Depth Slices and Shallow Subsurface Average Maps
This zipped shapefile provides maps showing electrical resistivity (ohm-meters) depth slices and shallow subsurface average derived from the Statewide Airborne Electromagnetic (AEM) Survey data available at https://data.cnra.ca.gov/dataset/aem. The AEM data for a depth slice are displayed using a local polynomial interpolation on a 1 kilometer line buffered around the flown flight line. The depth slice intervals were defined by the AEM data inversion geometry and were not resampled. The shallow subsurface average map represents the average over the 0-17 meter depth interval. The interpolation defined as the depth weighted average electrical resistivity value over the defined interval.
This table contains the individual budgets that make up the supplier’s urban water use objectives, as well as the sum of reported regulated demands, and the volumes of SBx7-7 targets. All fields were either pre-filled or auto-calculated within the reporting form.

The Data2HSM User Manual provides a quick‑start guide, setup and execution steps, tool descriptions, input and output options, and key assumptions and limitations. Data2HSM is a tool that allows users to generate hydrostratigraphic models and aquifer surfaces from AEM data, lithology logs, and geophysical logs. Possible outputs include: + Groundwater model layering prototypes + Hydrogeologic conceptual models + 3D lithologic models + Surfaces such as aquifer/aquitard bases, geologic formations, the water table, base of freshwater, or top of bedrock Data2HSM consists of one interface with three main tools: + ###Gaussian Mixture Model (GMM) GMM converts AEM data into 2D and 3D lithologic or stratigraphic models. Users can also include existing stratigraphic or texture models to guide the tool. GMM uses unsupervised machine learning to assign data points to user‑defined clusters that represent either lithologic groups (e.g., sand, clay, gravel) or stratigraphic units. When configured for stratigraphy, the tool uses prior geologic knowledge and a coordinate transformation to help maintain geologic consistency. + ###Smart Interpretation (SI) Smart Interpretation helps users rapidly delineate hydrogeologic surfaces such as aquifer/aquitard bases, the water table, the base of freshwater, or the top of bedrock. Users provide a small set of interpretations—either from past work or from other datasets—and SI uses polynomial regression informed by AEM data to complete the surface. An interactive 3D viewer allows additional interpretations using AEM sections, boring logs, and geologic cross‑sections. Multiple surfaces can be interpreted in one session. + ###Geological Pseudolabel Deep Neural Network (GeoPDNN) GeoPDNN is a deep‑learning tool that generates continuous 3D geological models from interval‑based datasets such as boring logs or AEM soundings. It takes in location coordinates and interval data and outputs a 3D stratigraphic model and surfaces marking the base of each unit. ###Key References: This manual draws on foundational research supporting Data2HSM’s methods, including: + [GeoPDNN 1.0: A semi‑supervised deep learning framework for 3D geologic modeling using pseudo‑labels](https://doi.org/10.5281/zenodo.10604091 "GeoPDNN 1.0: A semi‑supervised deep learning framework for 3D geologic modeling using pseudo‑labels") (Guo & X, 2023). + [Smart Interpretation – supervised statistical models for automated geological interpretations](https://doi.org/10.1007/s10596-017-9621-8 "Smart Interpretation – supervised statistical models for automated geological interpretations")(Gulbrandsen et al., 2017).

Texture2Par generates 3D texture models and aquifer parameter datasets for groundwater flow modeling. Written in Fortran, Texture2Par can be used standalone or within a larger automated workflow such as groundwater model calibration. Texture2Par can be used for generating the following: + ###Texture Model Texture2Par can be used to develop Texture Models. To develop Texture Models, Texture2Par uses ordinary, block, or indicator kriging and co‑kriging to convert lithology logs, and geophysical data interpreted for texture (from AEM or geophysical logs) into 3D texture models. It supports anisotropic and isotropic variograms and cross‑variograms. + ###Aquifer Properties Texture2Par can also be used to develop Aquifer Properties for Groundwater Models. To obtain Aquifer Properties, Texture2Par uses empirical relationships between texture and aquifer properties to estimate horizontal and vertical hydraulic conductivity, specific yield, and specific storage throughout a model domain. The tool also supports a pilot‑point approach to incorporate spatially distributed aquifer parameter measurements, such as pumping test results. Aquifer Properties can directly output parameter files for IWFM and MODFLOW. The Texture2Par User Manual provides an overview of the tool inputs, outputs, setup and execution, and limitations. ###Key References: + [Texture2Par User’s Guide: A Parameterization Utility for IWFM and MODFLOW, Version 1.0.0](https://data.cnra.ca.gov/dataset/svsim/resource/88cbfa06-a2e7-4078-8f76-a1044d32fe70 "Texture2Par User’s Guide: A Parameterization Utility for IWFM and MODFLOW, Version 1.0.0) (DWR, 2022). + [Texture2Par: A texture-driven tool for estimating subsurface hydraulic properties](https://doi.org/10.1016/j.envsoft.2025.106372 "Texture2Par: A texture-driven tool for estimating subsurface hydraulic properties") (Scantlebury et al., 2025.
