Description:
Abstract:
This data set consists of digital water-table contours for the Mojave River and the Morongo Ground-Water Basins. The U.S. Geological Survey constructed a water-table map of the Mojave River and the Morongo Ground-Water Basins for ground-water levels measured during the spring of 2000. Water-level data were collected from 498 wells to construct the contours. The water-table contours were digitized from the paper map which was published at a scale of 1:175,512. The contour interval ranges from 3,400 to 1,500 feet above sea level.
Purpose:
This data set is a digital representation of the contours presented on the map published in 2003, "Regional Water Table (2000) and Ground-Water-Level Changes in the Mojave River and the Morongo Ground-Water Basins, Southwestern Mojave Desert, California", by Gregory A. Smith, U.S. Geological Survey WRIR 02-4277, and make the data available for use with geographic information systems.
Supplemental_Information:
The Mojave River and the Morongo Ground-Water Basins are in the Mojave Desert region. The rapid growth in population in these basins, which is due, in part, to their proximity to Los Angeles, has increased the demand for water. Increased pumping to meet the needs of an increasing resident population has resulted in ground-water overdraft in parts of the ground-water basin (Smith 2002).

Lineage:
Process_Step:
Process_Description:
A tiff file was obtained from the original Adobe Illustrator file use to create the original map. The tiff file was then georeferenced using known township corners. The contours were then digitized from the georeferenced tiff.
Process_Date: 2003
Process_Step:
Process_Description:
The contours were edited to add the Line_type field and the WL field.
