Hydrologic investigations of urban watersheds in Texas were begun by the U.S. Geological Survey in 1954. Studies are now in progress in Austin, Dallas and Dallas County, Fort Worth, Houston, and San Antonio.
The Geological Survey, in cooperation with the Texas Department of Water Resources, began hydrologic studies in the Austin urban area in 1954. In cooperation with the city of Austin, the program was expanded in 1975 to include additional streamflow and rainfall gaging stations, and the collection of water-quality data. The objectives of the Austin urban hydrology study are as follows:1. To determine, on the basis of historical data and hydrologic analyses, the magnitude and frequency of flood peaks and flood volume.; 2. To determine the effect of urban development on flood peaks and volume.; 3. To ascertain the variation in water quality for different seasons from selected basins of varying urban development.
This report presents the basic hydrologic data collected in the Austin urban area for the 1976 water year (Oct. 1, 1976 to Sept. 30, 1976). To facilitate the pubication and distribution of this report at the earliest feasible time, certain material has been included that does not conform to the formal publication standards of the U.S. Geological Survey.
