Update to the groundwater withdrawals database for the Death Valley regional groundwater flow system, Nevada and California, 1913-2010

Groundwater withdrawal estimates from 1913-2010 for the Death Valley regional groundwater flow system (DVRFS) are compiled in a Microsoft Access database. This database updates two previously published databases (Moreo and others, 2003; Moreo and Justet, 2008). A total of about 38,000 acre-feet of groundwater was withdrawn from the DVRFS in 2010, of which 47 percent was used for irrigation, 22 percent for domestic, and 31 percent for public supply, commercial, and mining activities. The updated database was compiled to support ongoing efforts to model groundwater flow in the DVRFS.
