2014 Water-Table Contours of the Mojave River and the Morongo Groundwater Basins, San Bernardino County, California

During 2014, the U.S. Geological Survey and other agencies made approximately 1,026 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 610 wells, providing coverage for most of the basins. Twenty-four hydrographs show long-term (1930-2014) water-level conditions throughout the basins, and 9 short-term (1992 to 2014) hydrographs show the effects of recharge and discharge along the Mojave River. In addition, a water-level-change map was compiled to compare was compiled to compare the 2014 water levels to the 2012 water levels throughout the basins (479 wells).
