Projected effects of the proposed Tennessee Colony Reservoir on ground-water conditions in the alluvium of the Trinity River and Cedar Creek, Texas: preliminary results for the Trinidad area Projected effects of the proposed Tennessee Colony Reservoir on ground-water conditions in the alluvium of the Trinity River and Cedar Creek, Texas: preliminary results for the Trinidad area
The U.S. Army Corps of Engineers proposed the construction of Tennessee Colony Dam and Reservoir as part of a multipurpose plan for the Trinity River and tributaries between the Dallas-Fort Worth area and the Texas Gulf Coast. The Corps requested the assistance of the U.S. Geological Survey (1) to define the existing ground-water conditions in the alluvium of the Trinity River and Cedar...

A digital model for simulation of ground-water hydrology in the Houston area, Texas A digital model for simulation of ground-water hydrology in the Houston area, Texas
This report documents the construction and calibration of a digital model for the simulation of hydrologic conditions in the Chicot and Evangeline aquifers in the Houston area of southeastern Texas. The model is a five-layer finite-difference model, with a grid pattern of 63 x 67 nodes representing an area of 27,000 square miles, for simulation of three- dimensional ground-water flow...

Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1977 Hydrologic data for urban studies in the Dallas, Texas, metropolitan area, 1977
In August 1961, the Geological Survey, in cooperation with the city of Dallas, began a program of investigations designed to evaluate hydrologic factors affecting floods on several small streams in Dallas. During the 1977 water year, the original program was expanded to include the greater Dallas metropolitan area.

Sediment yields for selected streams in Texas Sediment yields for selected streams in Texas
The U.S. Geological Survey began a study to determine sediment yields for selected streams in Texas during the 1966 water year to provide information for areas in which sediment-yield data were meager or lacking. These data will aid in delineating problem areas and planning for water-resources development in the State. This report presents estimates of suspended-sediment loads and yields...

Availability of fresh and slightly saline ground water in the basins of westernmost Texas Availability of fresh and slightly saline ground water in the basins of westernmost Texas
Significant quantities of fresh ground water occur in the basin fill of the northern Hueco bolson and lower Mesilla Valley and in the Wildhorse Flat, Michigan Flat, Lobo Flat, and Ryan Flat areas of the Salt Basin; and may occur in Red Light Draw, Presidio bolson, and Green River valley. More than 20 million acre-feet of freshwater is estimated to be in storage in the basin fill of...

Chemical quality of water in abandoned zinc mines in northeastern Oklahoma and southeastern Kansas Chemical quality of water in abandoned zinc mines in northeastern Oklahoma and southeastern Kansas
Onsite measurements of pH, specific conductance, and water temperature show that water temperatures in seven mine shafts in northeastern Oklahoma and southeastern Kansas is stratified. With increasing sampling depth, specific conductance and water temperature tend to increase, and pH tends to decrease. Concentrations of dissolved solids and chemical constituents in mine-shaft water, such...

Gas-driven pump for ground-water samples Gas-driven pump for ground-water samples
Observation wells installed for artificial-recharge research and other wells used in different ground-water programs are frequently cased with small-diameter steel pipe. To obtain samples from these small-diameter wells in order to monitor water quality, and to calibrate solute-transport models, a small-diameter pump with unique operating characteristics is required that causes a minimum
