From abstract: The Hueco Bolson provides a substantial part of the municipal and industrial water supply of the El Paso area of Texas, New Mexico and Mexico. Although the supply of fresh ground water in the bolson is large, about 10.6 million acre-feet (13,070 hm^3) in 1973 in the Texas part of the bolson alone, the supply is being depleted.

Abstract: Rainfall and runoff data from drainage basins in the Houston metropolitan area and a 60-year rainfall record for the National Weather Service station, Houston-City, were used to simulate 60 annual flood peaks at 26 sites. Selected frequency characteristics, based on these simulated annual peaks are related to drainage area and percentage of impervious area. These relations which may be used to estimate the flood characteristics at ungaged sites, indicate that in the Houston metropolitan area, complete urbanization increases the magnitude of a 2-year flood nine times and increases the magnitude of a 50-year flood five times.

This report presents rock sample and uranium data examined from the Van Horn, Texas area. Over 300 rocks samples were analyzed for 30 elements.

This report examines the annual recharge to the Edwards Aquifer in San Antonio, Texas and how to collect annual recharge data. It includes maps and tables.

From Introduction: "The Corpus Christi Quadrangle, Texas (Fig. 1), was evaluated to a depth of 1500 m (5,000 ft) to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits."

Purpose and Scope: "The purpose of this study is to provide basic water supply data needed for future evaluation and selection of promising saline water conversion opportunities. This report presents information regarding the present and future supply situation of individual communities. Also presented is information on regional water plans with respect to provisions for municipal water supply."

From introduction: Salt occurs at depths less than 500 feet in six salt domes in Texas and Louisiana. Underground mining operations are being carried out in each of these domes. The following notes have been prepared in an effort to furnish data regarding chemical composition and structure of the rock salt in the shallow deposits.

This report presents "a technique for estimating the magnitude and frequency of floods in the Houston, Texas, metropolitan area." It includes a map, graph, and tables.

The information provided in this report follows the investigations of the use of dredged material islands made by colonial nesting seabirds and wading birds in Texas initiated in October 1976.
