Hydrologic Data for Urban Studies in the Austin, Texas Metropolitan Area, 1972
The purpose of this report is to present rainfall and runoff data for the Waller Creek and Wilbarger Creek study areas for the 1972 water year (October 1, 1971 to September 30, 1972).

The effect of heated water on the temperature and evaporation of Hyco Lake, North Carolina, 1966-72
Three levels of thermal loading of Hyco Lake by heat from two steam-electric generators have resulted in higher temperatures and increased evaporation in the 3,750-acre (1,518 square hectometer) lake. During the winter, local temperature increases of 34°F (19°C) were sometimes observed at the surface as heated water spread out on top of the cooler, more-dense, lake water, affecting areas as large

The quality of surface waters in Texas
The discharge-weighted average concentrations of dissolved solids, chloride, and ,sulfate for many of the principal streams in Texas are less than 500 mg/l (millijgraljls per liter), 250 mg/l, and 250 mg/l, respectively. At 65 of 131 sites on streams that were sampled at least 10 times, the biochemical oxygen demand of at least half the samples exceeded 3.0 mg/l. At 20 of the sites, the dissolved-

Movement and dispersion of soluble materials in Salem Creek, Muddy Creek, and Yadkin River between Winston-Salem and Salisbury, North Carolina
Wastes entering the Yadkin River from the Winston-Salem area, particularly during heavy rains, resulted in several major fish kills in the late 1960's and early 1970's. The actions undertaken to solve this problem, included the collection of data on the time of travel and dispersion characteristics of the tributaries draining the Winston-Salem area and of the main stem of the Yadkin below their co

Hydrology of the Dismal Swamp, Virginia-North Carolina
The Dismal Swamp, on the border between eastern Virginia and North Carolina is one of the few remaining large (approximately 210,000 acres) areas of wet wilderness in the eastern United States. There has been much speculation concerning the hydrologic conditions that led to the formation of the swamp.Oaks and Coch (1973) recently completed a detailed investigation of the geology and morphology of

Analog-model studies of ground-water hydrology in the Houston District, Texas
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 altitudes of the

Land-surface subsidence in the Houston-Galveston region, Texas
The pumping of large amounts of ground water in the Houston-Galveston region, Texas, has resulted in water-level declines of as much as 200 feet (61 metres) in wells completed in the Chicot aquifer and as much as 325 feet (99 metres) in wells completed in the Evangeline aquifer during 1943-73. The maximum annual rates of decline for 1943-73 were 6.7 feet (2.0 metres) in the Chicot aquifer and 10.8

Summary appraisals of the Nation's ground-water resources; Texas Gulf region
Ground water in the Texas-Gulf Region is a large and important resource that can provide a more significant percentage of the total water supply of the region. Total water requirements within the region are projected to rise sharply from 14 million acre-feet (17 cubic kilometres) in 1970 to nearly 26 million acre-feet (32.cubic kilometres) in 2020. About half of the water used in 1970 was ground w
