The purpose of this report is to present rainfall and runoff data for the Waller Creek and Wilbarger Creek study areas for the 1973 water year (October 1, 1972 to September 30, 1973).

Annual recharge data obtained from historical records and mean-annual precipitation data computed from rainfall records were used to develop simple linear-regression equations for use in estimating annual recharge for seven subbasins in the San Antonio area. Adjustments were made to the precipitation parameter to account for the effects of year-end storms. The standard errors of estimate of the re

Tritium concentrations of samples from 50 wells and springs in the Edwards aquifer in the San Antonio area of Texas have been analysed. Tritium now in the aquifer is partly natural cosmic ray produced tritium, but most is tritium produced by atmospheric thermonuclear tests in the 1950's and early 1960's. The tritium levels in atmospheric precipitation and streams recharging the Edwards are present

The effects of urbanization on flood characteristics of streams in the Dallas metropolitan area were studied by use of a digital model of the hydrologic system. The model was calibrated by using observed rainfall and runoff data from 19 storms in six basins having various degrees of urbanization. The calibrated models were used with a 57- year rainfall record to simulate 57-year records of annual

Floods produced by Hurricane Beulah during September and October 1967 were outstanding because of the magnitude of the stage and discharge and because of the number of river basins affected. Previously known maximum stages were exceeded, at the downstream station, in five river basins in Texas by amounts ranging from 2.7 feet at Guadalupe River near Tivoli to 9.2 feet at Aransas River near Skidmor

Removal of water, oil, and gas from the subsurface in Harris County has caused declines in fluid pressures, which in turn have resulted in subsidence of the land surface. Subsidence in the area of Burnett, Scott, and Crystal Bays near Baytown is becoming critical because much of the area is now subject to inundation by high tides. Production of oil and gas from the Goose Creek Field on the southea

The water-resources investigations program of the Geological Survey has the objective of seeing that the Nation's water resources are appraised and that the necessary water data to develop and manage them efficiently are available when needed. In carrying out this objective, the Survey is the primary source of hydrologic data that are basic not only to the quantification of the water resource but

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.
