CNRWA collects water level measurements from 51 wells in 12 groundwater basins to: determine temporal trends, identify the occurrence and movement of groundwater and help quantify subsurface flow between basins. The wells were selected in concert with the U.S. Geological Survey and the Nevada Division of Water Resources (DWR) to fill gaps. DWR does not collect groundwater pumping data from wells in these 12 groundwater basins. Click for: Groundwater Basins of Nevada Map
