This polygon shapefile contains the boundaries of 517 groundwater basins and subbasins as defined by the California Department of Water Resources as last modified by the Basin Boundary Emergency Regulation adopted on October 21, 2015. Groundwater basins are represented as polygon features and designated on the basis of geological and hydrological conditions - usually the occurrence of alluvial or unconsolidated deposits. When practical, large basins are also subdivided by political boundaries, as in the Central Valley. Basins are named and numbered per the convention of the Department of Water Resources. The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR GIS Spatial Data Standards.
Bulletin 118 defines the recognized groundwater basins and subbasins throughout the State of California. The Bulletin 118 document provides information on these basins/subbasins and the nature and extent of groundwater occurrence and management within the State. The Bulletin 118 dataset makes the geographic locations and extent of the 517 basins/subbasins publically available, for use in external mapping/GIS applications.

This point shapefile represents the depth to groundwater below the ground surface in California during fall of 2013. These data show depth to groundwater values collected from wells. Depth information is represented in feet below the ground surface. Increasing values indicate increasing depth to groundwater (or deeper/lower water levels). Negative values indicate that the groundwater level is above 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.

This point shapefile represents the depth to groundwater below the ground surface in California during fall of 2014. These data show depth to groundwater values collected from wells. Depth information is represented in feet below the ground surface. Increasing values indicate increasing depth to groundwater (or deeper/lower water levels). Negative values indicate that the groundwater level is above 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 raster dataset (GeoTIFF) represents the depth to groundwater below the ground surface using a color ramp. These data represent groundwater levels in California during fall 2013. 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. 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.
