  1. Title: Groundwater Elevation Contours, California, Spring 2012

    Contributors:

    Summary: This line shapefile represents groundwater elevation in California for spring 2012. This layer is a smoothed approximation of the groundwater level 'surface' based on the measurement data. The measurement values may not exactly match the contour values because of the smoothing process. Water level measurements are selected based on measurement data and well construction information (where available) and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers. 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 Contours, California, Spring 2012. California Department of Water Resources. Available at: http://purl.stanford.edu/dw932vj1291. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.

  2. Title: Groundwater Elevation Change, California, Spring 2006 to Spring 2016

    Contributors:

    Summary: This point shapefile represents changes in groundwater levels in California. These data represent groundwater changes between spring 2006 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. 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, California, Spring 2006 to Spring 2016. California Department of Water Resources. Available at: http://purl.stanford.edu/bm205gp3500.

  3. Title: Groundwater Depth Contours, California, Spring 2016

    Contributors:

    Summary: This line shapefile represents the depth to groundwater below the ground surface in California during the spring of 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 contour values because of the contour smoothing process. Depth information is represented in feet below the ground surface. Water level measurements are selected based on measurement data and well construction information (where available) and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers. 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).
