Mojave Region Water-Level Study, 2012

Regional water-table maps of the Mojave River and Morongo ground-water basins have been published in reports by the U.S. Geological Survey (USGS) every two years since 1992. The water-level reports for the years 1992-2004 were published as USGS Water-Resources Investigations Reports or Scientific Investigations Reports and are available online as separate Portable Document Fomat (pdf) formatted reports, which can be accessed on the "References" page on this website; the water-level contours from most of the water-level maps are available also on this website: data page. Beginning in 2006, the biannually scheduled water-level reports and maps will be published on this interactive mapping website; any future water-level studies also will be available on this website..\r\n\r\nThe water-level studies include water-level contour maps drawn from data measured from wells during each study. Most of the studies demonstrate water-level changes by hydrographs that show long-term and short-term water-level changes, and by maps that compare water levels at individual wells between two consecutively published reports.
