The major water-bearing units in the Houston district are the Chicot and the Evangeline aquifers. The Chicot aquifer overlies the Evangeline aquifer, which is underlain by the Burkeville confining layer. Both aquifers consist of unconsolidated and discontinuous layers of sand and clay that dip toward the Gulf of Mexico. Heavy pumping of fresh water has caused large declines in the...

The need for additional water supplies in the Houston area prompted construction of Lake Livingston on the Trinity River in Polk and San Jacinto Counties, about 60 miles (96 km) northeast of Houston, as a source of surface water for municipal supply, industrial use, and irrigation. Water from the Lake Livingston will become available to users in the Houston area early in 1976.

The proposed water-quality network for the Sabine River Basin of Texas and Louisiana consists of nine monitoring stations, a central control station, a slave-central station, and a leased-line telecommunications system. This monitoring network would provide continuous transmission of water-quality data to the office of the water manager. Level I operations at a proposed site would...

Water resources data for the 1972 water year for Texas include records of data for the chemical and physical characteristics of surface water. The records were collected by the Water Resources Division of the U.S. Geological Survey under the direction of I.D. Yost, district chief. These data represent that portion of the National Water Data System collected by the U.S. Geological Survey...

The U.S. Geological Survey, in cooperation with the Texas Water Development Board, began hydrologic studies in the Austin urban area in 1954. The objectives of this project are as follows: 1. To determine the effects of progressive urbanization on infiltration, rates of peak discharge, and rainfall-runoff relations in the Waller Creek watershed. 2. To provide rainfall-and-runoff data...

Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage outflow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-waterwithdrawals will continue to cause land-surface...

Because of increasing concern about the continuing decline of water levels in the Houston area, an electric analog model was used to determine the effects on the potentiometric surfaces resulting from recharging water through wells along the Houston Ship Channel into the two major aquifers, the Chicot and Evangeline. The model conditions simulated for this study are too complex to be...

The total inflow of water to the lower Mesilla Valley in 1970 was 390,510 acre-feet. Of this amount, 43,300 acre-feet was consumptively used by crops and phreatophytes and 4,700 acre-feet was lost by evaporation. Ground-water storage increased by 320 acre-feet, and 360,860 acrefeet left the valley as surface- and ground-water outflow. Ground-water recharge was approximately 26,170 acre...
