2012 Water Levels - Mojave River and the Morongo Groundwater Basins

During 2012, the U.S. Geological Survey and other agencies made approximately 2,500 water-level measurements in the Mojave River and Morongo groundwater basins. These data document recent conditions and, when compared with previous data, changes in groundwater levels. A water-level contour map was drawn using data from about 575 wells, providing coverage for most of the basins. Twenty-eight hydrographs show long-term (1930-2012) water-level conditions throughout the basins, and 9 short-term (1992 to 2012) hydrographs show the effects of recharge and discharge along the Mojave River. In addition, a water-level-change map was compiled to compare 2010 and 2012 water levels throughout the basins (516 wells).
