Ground-water data for the Salt Basin, Eagle Flat, Red Light Draw, Green River Valley, and Presidio Bolson in westernmost Texas

Abstract

From October 1971 through October 1974, the U.S. Geological Survey collected ground-water data in the basins in Texas west of the Pecos River drainage area and northwest of the Big Bend country. The basins included are, from east to west: The Presidio Bolson; the Salt Basin; Green River Valley, Eagle Flat, and Red Light Draw. These data, which were collected in cooperation with the Texas Department of Water Resources (formerly Texas Water Development Board), will provide information for a continuing assessment of water availability within the State. The data-collection program consisted of an inventory of all major irrigation, municipal-supply, and industrial wells; selected stock and domestic wells; and selected springs. Water samples were collected from representative wells and springs for chemical analyses. These data, together with data from geophysical surveys and test drilling, will be used to prepare a report on the availability of ground water in the basins of westernmost Texas. Data collected prior to this study are contained in the reports listed in the selected references. The well-numbering system is shown on figure 1, and the locations of the wells, test holes, and springs are shown on figures 2-8. The records of wells and springs are given in table 1, and the water levels in selected observation wells in the Salt Basin are given in table2. The chemical analyses of water samples from selected wells, test holes, and springs are given in table 3.
