  1. Title: wdpr24 - Private Water Districts for California 1:24,000-scale

    • Polygon data
    • 2003
    Contributors:

    Summary: Private Water District boundaries are areas where private contracts provide water to the district in California. This database is designed as a regions polygon database and is updated when sufficient number of changes have occured to warrant an update. Updates are determined by the needs of the local office. Separate databases are used for maintenance purposes. Boundaries are continually being updated as changes are identified by the Water Districts. The boundaries are not current for all Water Districts found in the database at the same time due to the update methods employed. There may be conflicts in the boundaries between districts due to the time of update and review process associated with each Water District. Other problems may be associated with Water District name changes that have not been updated and possibly new Water Districts not being included due to lack of information. This database represents the most current and accurate understanding of the boundary location and current name of the Water Districts.

  2. Title: Groundwater Elevation Change Color Ramp, California, Spring 2015 to Spring 2016

    • Raster data
    • 2016
    Contributors:

    Summary: This raster dataset (GeoTIFF) represents groundwater elevation in California using a color ramp. These data represent groundwater changes between spring 2015 and spring 2016. This layer is a smoothed approximation of the groundwater level 'surface' based on the measurement data. The measurement values may not exactly match the color ramp values because of the smoothing process. This layer is intended to be used as a compliment to data, reports, and other information provided by the California Groundwater Information Center. California Department of Water Resources. (2016). Groundwater Elevation Change Color Ramp, California, Spring 2015 to Spring 2016. California Department of Water Resources. Available at: http://purl.stanford.edu/gt506qf5033. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  3. Title: Groundwater Elevation Change, California, Spring 2013 to Spring 2016

    • Point data
    • 2016
    Contributors:

    Summary: This point shapefile represents changes in groundwater levels in California. These data represent groundwater changes between spring 2013 and spring 2016. Each point shows the calculated difference between the measured groundwater levels from the time period. The change in groundwater level is plotted on the map only if a measurement exists in both time periods as well. The colored points in the measurements layer show the location of all wells where the groundwater level change is determined.
