This point shapefile represents changes in groundwater levels in California. These data represent groundwater changes between fall 2010 and fall 2015. 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, Fall 2010 to Fall 2015. California Department of Water Resources. Available at: http://purl.stanford.edu/zj068kg9781. This layer is presented in the WGS84 coordinate system for web display purposes. Downloadable data are provided in native coordinate system or projection.
