Rapid urban development in the Austin metropolitan area, Texas, is causing concern about increasing peak discharges from storm runoff and the degradation of the quality of water in receiving streams, lakes, and aquifers. In an attempt to decrease peak discharges and improve water quality, runoff controls are being required in some watersheds. This report summarizes the precipitation...

Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, and Houston. Studies have been completed in the Dallas, Fort Worth, and San Antonio areas. The Geological Survey, in cooperation with the Texas Department of Water Reources, began hydrologic studies in the Austin urban area in 1954. In...

As of January 1, 1987, the surface-water data-collection network in Texas included 376 continuous streamflow, 76 continuous or daily reservoir-content, 34 gage height, 16 crest-stage partial-record, 8 periodic discharge through range, 33 floodhydrograph partial-record, 9 flood-profile partial-record, 36 low-flow partial-record, 46 daily chemical-quality, 19 continuous-recording water...

During 1980-84, ground-water withdrawals from the Chicot and Evangeline aquifers in the Houston district decreased from 511 million gallons per day to 444 million gallons per day. This 13-percent decrease was due to the increased availability of surface water and a decreased demand for water. The largest decreases in ground-water withdrawals occurred in the Houston area. Ground-water...

The National Water Commission recommended that the U.S. Geological Survey conduct intensive studies of the important regional aquifer systems in the United States, particularly those with declining water levels and deteriorating water quality. The result has been a series of Regional Aquifer-System Analysis (RASA) studies, one of which is the West Gulf Coast RASA study (Grubb, 1984). The...

Water in Cedar Creek Reservoir in northeast Texas had volume-weighted average concentrations of less than 140 milligrams per liter of dissolved solids, less than 30 milligrams per liter of dissolved sulfate, and less than 25 milligrams per liter of chloride between vh nuary 1977 and August 1984. The water was soft to moderately hard; the total hardness concentrations ranged from 55 to 75

Catastrophic floods caused by record rainfall occurred in central Texas during August 1-4, 1978. Torrential rain initiated by the remnants of tropical storm Amelia fell over south-central Texas during August 1-3, and very intense rain due to the interaction between the cold front and maritime air mass fell over north-central Texas on August 3-4. Rainfall of more than 48 inches near...

The Water Resources Division of the U.S. Geological Survey, in cooperation with Federal, State, and City agencies, obtains a large amount of data pertaining to the water resources of Texas each water year. Such data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of the State. To make these data readily...

Water-resources activities in Texas include collecting of hydrologic data, performing interpretive studies, and conducting research. This report describes the activities of the Water Resources Division of the U.S. Geological Survey in Texas for fiscal years (October to September) 1985 to 1986.

Since 1973, personnel of the Texas District, Water Resources Division of the U.S. Geological Survey have written and published approximately 300 reports concerning the water resources of Texas. These reports vary considerably in subject matter, complexity, format, desired audience, and publication outlet. Some of the reports have been published in different outlets of U.S. Geological...
