Summary

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. The California Groundwater Units dataset classifies and delineates the State into one of three groundwater based polygon units: (1) those areas defined as alluvial groundwater basins or sub-basins (DWR, 2002), (2) highland areas that are adjacent to and topographically upgradient of groundwater basins, and (3) highland areas not associated with any groundwater basin. In total, 938 Groundwater Units are represented. The Groundwater Unit dataset relates [...]

Purpose

This dataset was developed to classify and delineate all areas of California into three categories which will be used in subsequent hydrologic studies. Many studies and reports including the Groundwater Ambient and Assessment Program (GAMA) use the DWR groundwater basin (or sub-basin) as the basic unit. With this dataset, it is now possible to relate a groundwater basin with its highland area. Highland areas not associated with a groundwater basin were also identified.
