This report contains rainfall, runoff, and storage data collected during the 1976 water year for a 75.5 sq mi area above the stream-gaging station Little Elm Creek near Aubrey, Texas. Floodflows from 35.7 sq mi of the area are regulated by 16 floodwater-retarding structures constructed by the Soil Conservation Service. During the 1976 water year, five storm periods were selected for...

On June 27, 1975, the city of Ames and vicinity sustained severe flooding from Squaw creek and the south Skunk River. The storm which preceded the flood was net particularly outstanding in its intensity or duration. However, antecedent conditions plus the timing and direction of the storm were "ideally tuned" to cause the flood. In terms of magnitude of discharge as well as of damages...

Removal of water, oil, and gas from the subsurface in Harris and Galveston Counties has caused declines in fluid pressures, which in turn have resulted in subsidence of the land surface. Subsidence of the land surface at Moses Lake in due principally to the removal of ground water in adjacent areas. Significant subsidence of the land surface at Moses Lake began after 1900, and as much as...

Water resources data for the 1975 water year for Georgia consists of records of stage, discharge, · and water quality of streams; stage and contents of lakes and reservoirs. This report contains discharge records for 91 gaging stations; stage only records for one gaging station; stage and contents for 16 lakes and reservoirs; water quality for 16 continuous stations and 78 periodic...

A stream-reservoir model was developed to simulate the operation of the Lakes Marion-Moultrie, South Carolina, reservoir system. The reservoir system is operated under the assumption of a 3-day prior knowledge of inflows. This information is attainable from the ooperational reservoir-inflow forecasting model developed in the Part I report. The model, developed for this part of the study

The concentrations of dissolved solids, chloride, and sulfate in Livingstone Reservoir on the Trinity River in southeastern Texas usually average less than 250 mg/1 (milligrams per litre), 40 mg/1, and 50 mg/1, respectively. The water is usually hard or moderately hard (61 to 180 mg/1 as calcium carbonate). The concentrations of principal dissolved constituents in the reservoir are...

The Hueco Bolson provides a substantial part of the municipal and industrial water supply of the El Paso area of Texas, New Mexico, and Mexico. Although the supply 6f fresh ground water in the bolson is large, about 10.6 million acre-feet (13,070 hm3) in 1973 in the Texas part of the bolson alone, the supply is being depleted. A two-layer digital model of the Hueco Bolson was developed...

Interpretations based on analyses of inorganic constituents, dissolved organic carbon, and tritium in ground water and surface waters indicate that the Houston Ship Channel is the source of salt water that has been detected in shallow wells between Baytown and Houston, Texas. Analyses of the ratios of the stable isotopes of carbon, sulfur, hydrogen, and oxygen were inconclusive as to the...

The purpose of this report is to present rainfall and runoff data for the Waller Creek and Wilbarger Creek study areas for the 1974 water year (October 1, 1973 to September 30, 1974).
