Hydrogeologic factors that affect the flowpath of water in selected zones of the Edwards Aquifer, San Antonio region, Texas
The Edwards aquifer in the San Antonio region supplies drinking water for more than 1 million people. Proper development and protection of the aquifer is a high priority for local and State authorities. To better understand the flow of water in two major flowpaths in the Edwards aquifer, stratigraphic, structural, hydrologic, and geochemical data were analyzed. The western Medina flowpath is in pa

Trends in nutrient inflows to the Gulf of Mexico from streams draining the conterminous United States, 1972-93
Trends are computed for nutrient inflows from 37 streams discharging into the Gulf of Mexico. The drainage areas of these streams represent about 86 percent of the drainage area to the Gulf from the conterminous United States. The period analyzed varies for each stream, but generally includes water years 1972-93. Stations included in this analysis primarily are part of the National Stream Quality

Index of stations: Surface-water data-collection network of Texas, September 1995
As of September 30, 1995, the surface-water data-collection network of Texas (table 1) included 305 continuous-recording streamflow stations (D), 28 gageheight record only stations (G), 23 crest-stage partialrecord stations (C), 42 flood-hydrograph partial-record stations (H), 33 low-flow partial-record stations (L), 19 continuous-recording temperature and conductivity stations (M2), 5 continuous-
Hydrogeologic framework of the Edwards-Trinity aquifer system, west-central Texas
The Edwards-Trinity aquifer system underlies about 42,000 square miles of west-central Texas, where mostly gently dipping Lower Cretaceous strata comprise three regional aquifers and two regional confining units. The aquifers are the Edwards Aquifer of the Balcones fault zone, the Trinity Aquifer of the Balcones fault zone and Hill County, and the Edwards-Trinity Aquifer of the Edwards Plateau and

Water-level altitudes 1996, water-level changes 1977-96 and 1995-96, and compaction 1973-95 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1977 and compation since 1973 in the Chicot and Evangeline aquifers i the Houston-Galveston region, Texas.

Ground Water Atlas of the United States: Segment 4, Oklahoma, Texas
The two States, Oklahoma and Texas, that compose Segment 4 of this Atlas are located in the south-central part of the Nation. These States are drained by numerous rivers and streams, the largest being the Arkansas, the Canadian, the Red, the Sabine, the Trinity, the Brazos, the Colorado, and the Pecos Rivers and the Rio Grande. Many of these rivers and their tributaries supply large amounts of wat

Peak-flow frequency and extreme flood potential for streams in the vicinity of the Highland Lakes, central Texas
The Highland Lakes on the Colorado River are in an area periodically threatened by large storms and floods. Many storms exceeding 10 inches (in.) in depth have been documented in the area, including some with depths approaching 40 in. These storms typically produce large peak discharges that often threaten lives and property. The storms sometimes occur with little warning. Steep stream slopes and

Water-quality assessment of the Trinity River Basin, Texas - Nutrients in streams draining an agricultural and an urban area, 1993-95
Water samples collected from streams draining an agricultural area in the west-central part of the Trinity River Basin upstream from the Richland-Chambers Reservoir and from streams draining an urban area in the Dallas-Fort Worth metropolitan area during March 1993 - September 1995 were analyzed for nutrients (nitrogen and phosphorus compounds). A comparison of the data for agricultural and urban
