Vegetation - Fallbrook Naval Weapons Station [ds2958]

<div style='text-align:Left;'><div><div><p><span>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. </span></p></div></div></div>

Vegetation - Death Valley National Park [ds3305]

<div style='text-align:Left;'><div><div><p><span>Death Valley National Park (DEVA) is a very large, 3.4-million-acre (1.4 hectares) unit of the National Park Service (NPS) located in California on the eastern border with Nevada. To better understand and document the vegetation diversity at DEVA, the NPS, the National Vegetation Inventory Program (NVIP), and the NPS Mojave Desert Inventory and Monitoring Network (MOJN) opened a vegetation inventory effort here in 2010. </span></p><p><span>The NPS contracted the California Native Plant Society (CNPS) and the University of Nevada at Las Vegas (UNLV) to collect field data (111 classification plots and 518 observation points) for the project, which was combined with legacy data (1,242 samples) for analysis. CNPS analyzed the data to create the vegetation classification for the project following revised US National Vegetation Classification (USNVC) standards. 85 plant alliances and 186 plant associations were classified in DEVA as a result. NVIP then contracted Cogan Technology, Inc. (CTI) to create the digital vegetation map layer for the project area. The resulting spatial database and vegetation map layer were created using a combination of 2020 (California) and 2019 (Nevada) National Agriculture Imagery Program (NAIP) basemap data, ground-based verification efforts, and a two-step, or hybrid mapping approach that used both manual and automated techniques. By comparing the vegetation signatures on the imagery to the field data, 90 map units (74 vegetated and 16 land-use/land-cover) were developed and used to delineate the plant communities. The interpreted vegetation polygons were then digitized into a Geographic Information System (GIS) layer that was field-tested, reviewed, and revised. The map adheres to the USNVC standards. The minimum mapping unit (MMU) is 0.5 hectare (1.2 acres). </span></p><p><span>CTI contracted Coast-to-Coast Botany and the Rio Grande Institute to collect the accuracy assessment (AA) field data alongside NPS. CTI then conducted the AA analysis. The final DEVA vegetation map layer was assessed for overall thematic accuracy at 82% with a Kappa value of 89%.

Urban Retail Water Supplier - Water Conservation, Supply, and Demand (June 2014 onwards)

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.

County SB 552 Status Dashboard Data and Drought Resilience Plans

This dataset supports the County SB 552 Progress Dashboard, which is published on DWR’s [County Drought Resilience Planning webpage](https://water.ca.gov/Programs/Water-Use-And-Efficiency/SB-552/County-Drought-Resilience-Planning-Assistance-Program). The dashboard summarizes county-reported information on SB 552 implementation, including the status of drought and water shortage task force formation, drought resilience plan development, and the types of planning assistance counties have received from DWR (financial or direct technical assistance).

This page also links to a DWR-hosted document library containing completed County Drought Resilience Plans. Senate Bill (SB) 552 requires counties to improve drought and water shortage preparedness for state small water systems and domestic wells by establishing a standing Drought and Water Shortage Task Force and developing a County Drought Resilience Plan. These plans describe local drought and water shortage risks and potential interim and long-term solutions for state small water systems and domestic wells and may be stand-alone documents or incorporated into existing county plans.

The dashboard data and linked plans do not indicate compliance with SB 552 and do not constitute review, approval, or endorsement of any planning documents or processes. DWR does not review or approve plans for SB 552 compliance, nor direct or monitor county task force processes.

This dataset and dashboard were developed in response to frequent questions from counties about how SB 552 is being implemented statewide.

If you are county staff and would like to update your county’s information, please complete [this form](https://cadwr.app.box.com/s/030ohmm8vr33yfioa5e0czo0hlmljpey) and email it to CountyDRP@water.ca.gov.

Spatial CIMIS ETo maps — Daily Reference Evapotranspiration for California

🔔 Full-year 2025 data now available — Complete daily ETo for January–December 2025 has been published, replacing the partial-year v1 file. See the Change Log for details.

This dataset contains daily grass-reference evapotranspiration (ETo) maps for California at 2 km spatial resolution. The ETo values are expressed in millimeters (mm) per day.  Spatial data are provided in EPSG:3310 (NAD83 / California Albers) with units in meters.

ETo values are calculated statewide using the ASCE-Penman-Monteith equation (ASCE-PM), with required input parameters including solar radiation, air temperature, relative humidity, and wind speed at two meters height.
Daily solar radiation is derived from NOAA GOES satellite imagery using the Heliosat-II model, which converts visible-band satellite images into global horizontal irradiation at ground level. Air temperature, relative humidity, and wind speed are interpolated across the 2 km grid from CIMIS weather station measurements using Spline interpolation. This hybrid method allows spatially distributed ETo maps statewide, filling gaps where station coverage is sparse. Refer to https://cimis.water.ca.gov/SpatialData.aspx and the “Daily reference evapotranspiration for California using satellite imagery and weather station measurement interpolation” (Civil Engineering and Environmental Systems, October 2007) for detailed methodology.

The dataset is provided in Cloud-Optimized GeoTIFF (COG) files — one per year, enabling efficient streaming and subset access without downloading entire files. Each COG contains daily ETo values in a 2×2 km grid, covering 2004 through the most recently available year. Note that the current year’s dataset may have a lag of several months before all daily values are finalized and published.
