Regional water table (2010) in the Mojave River and Morongo groundwater basins, Southwestern Mojave Desert, California

U.S. Geological Survey (USGS) | February 23rd, 2012

Data for static water-levels measured in about 610 wells during January through June 2010 by the U.S. Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water districts were compiled to construct a regional water-table map, which shows the altitude of the water table and general direction of groundwater movement in and around the Mojave River and Morongo groundwater basins. Water-level contours from the 2008 water-level map (Stamos and others, 2009) were used as a guide to interpret the 2010 water-level contours in areas where 2010 water-level data were not available. In addition to being available on the interactive map,the 2010 water-level data and contours are shown for the entire area of the Mojave River and Morongo groundwater basins on Plate 1 greater detail of the Warren subbasin in the Morongo groundwater basin is shown on Plate 2. Historical water-level data from the National Water Information System (NWIS) database were used in conjunction with data collected for this study to construct 37 water-level hydrographs to show both long-term (1930 - 2010) and short-term (1990 - 2010) water-level changes in the Mojave River and Morongo groundwater basins. Water-level changes between spring 2008 and spring 2010 were determined by comparing water levels measured in the same well during both periods. Water-level changes between the studies on this website can be displayed on the interactive map by entering the years of interest.

Regional Water Table (2012) in the Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California

U.S. Geological Survey (USGS) | December 31st, 2012

Data for static water-levels measured in about 580 wells during March-May 2012 by the U.S. Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water

Data for static water-levels measured in about 580 wells during March-May 2012 by the U.S. Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water districts were compiled to construct a regional water-table map. This map shows the elevation of the water table and general direction of groundwater movement in and around the Mojave River and Morongo groundwater basins. Water-level measurements recorded by the USGS and MWA staff were compiled according to the procedures described in the Groundwater Technical Procedures of the U.S. Geological Survey (Cunningham and Schalk, 2011). Water-level data submitted by cooperating local water districts were collected by using procedures established by the corresponding agency. All data were compared to historical data for quality-assurance purposes. Water-level contours from the 2010 water-level map (Smith and others, 2011) were used as a guide to interpret the 2012 water-level contours in areas where 2012 water-level data were not available. In addition to being available on the interactive map, 2012 water-level data and contours are shown for the entire area of the Mojave River and Morongo groundwater basins on plate 1; greater detail of the Warren subbasin in the Morongo groundwater basin is shown on plate 2. Water-level data for 2012 are accessible through the website by clicking on the 2012 button above the title on the Water Levels page. Historical water-level data from the National Water Information System (NWIS) database were used in conjunction with data collected for this study to construct 36 water-level hydrographs to show long-term (1930-2012) and short-term (1990-2012) water-level changes in the Mojave River and Morongo groundwater basins. Water-level changes between the spring of 2010 and spring of 2012 were determined by comparing water levels measured in the same well during both periods. Water-level changes between the studies on this website can also be displayed on the interactive map by selecting the years of interest from the Groundwater Data menu.

Regional water table (2014) in the Mojave River and Morongo Groundwater Basins, southwestern Mojave Desert, California

U.S. Geological Survey (USGS) | June 28th, 2016

Data for static water-levels measured in about 610 wells during March-April 2014 by the U.S. Geological Survey (USGS), the Mojave Water Agency (MWA), and other local wate

Data for static water-levels measured in about 610 wells during March-April 2014 by the U.S. Geological Survey (USGS), the Mojave Water Agency (MWA), and other local water districts were compiled to construct a regional water-table map. This map shows the elevation of the water table and general direction of groundwater movement in and around the Mojave River and Morongo groundwater basins. Water-level measurements recorded by the USGS and MWA staff were measured and compiled according to the procedures described in the Groundwater Technical Procedures of the U.S. Geological Survey (Cunningham and Schalk, 2011). Water-level data submitted by cooperating local water districts were collected by using procedures established by the corresponding agency, and compiled according to the procedures described in the Groundwater Technical Procedures of the U.S. Geological Survey (Cunningham and Schalk, 2011). All data were compared to historical data for quality-assurance purposes. Water-level contours from the 2012 water-level map (Teague and others, 2014) were used as a guide to interpret and shape the 2014 water-level contours in areas where 2014 water-level data were not available; these contours are shown as dashed (approximate) on the water-table map. In addition to being available on the interactive map, 2014 water-level data and contours are shown for the entire area of the Mojave River and Morongo groundwater basins on Plate 1. Water-level data for 2014 are accesible through the website by clicking the 2014 Sites button on the Data Downloads page.

Regional Water Table (2016) in the Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California

U.S. Geological Survey (USGS) | December 27th, 2017

Data for static groundwater-levels measured in about 645 wells during the period of January-April 2016 by the United States Geological Survey (USGS), the Mojave Water Age

Data for static groundwater-levels measured in about 645 wells during the period of January-April 2016 by the United States Geological Survey (USGS), the Mojave Water Agency, and other local water districts were compiled to construct a regional water-table map. The downloadable shapefile shows the elevation of the water table in the Mojave River and Morongo groundwater basins. This dataset is a digital representation of the contours presented on Plate 1 of Regional Water Table (2016) in the Mojave River and Morongo Groundwater Basins, Southwestern Mojave Desert, California: U.S. Geological Survey Scientific Investigation Map, doi:10.5066/sim3391, published by Meghan C. Dick and Adam R. Kjos. It is a continuation of a study first published in 2007. The initial version of the Scientific Investigations Report (SIR) includes data for 1992 to 2008 (SIR 2007-5097). This data release also serves as a repository for a selection of tabular data used in the 2016 Mojave River and Morongo groundwater basin regional water table map. The data represent water level measurements provided by cooperating water agencies whose data collection standards may not meet the criteria set forth by the U.S. Geological Survey for inclusion in the USGS National Water Information System (NWIS).
