Information on major new water wells in Chambers, Liberty, and Montgomery Counties was compiled by the U.S. Geological Survey from 1980 through 1984. This report presents the results of the hydrologic data collection on new largecapacity and other selected wells, including well location and completion data, drillers' logs of the strata penetrated, water levels, and chemical quality of...

This report consists of: (1) Four maps that present data on water level changes during 1977-86 and 1985-86 in the Chicot and Evangeline aquifers, Houston, Texas, and (2) one set of graphs and one map that present data on land subsidence and compaction of subsurface materials for 1973-86. (USGS)

As of January 1, 1986, the surface-water data-collection network in Texas operated by the U.S. Geological Survey included 386 streamflow, 87 reservoir-contents, 33 stage, 10 crest-stage partial-record, 8 periodic discharge through range, 38 flood-hydrograph partial-record, 11 flood-profile partial-record , 36 low-flow partial-record 2 tide-level, 45 daily chemical-quality, 23 continuous...

The effects of urbanization on flood peaks in streams in the Austin metropolitan area were studied in two separate analyses. In the first analysis, annual peak discharge records at 13 streamflow-gaging sites were used to compute a recorded flood frequency relation for each site. Rainfall and streamflow data for 10 to 20 storms for each of these sites were used to calibrate a rainfall...

Urban development over the Edwards aquifer in the Austin, Texas, area has caused concerns about the availability and quality of water in the aquifer. The study area, the Edwards aquifer that discharges to Barton Springs, includes parts of Travis and Hays Counties and extends from the city of Kyle to the Colorado River. A large part of the aquifer lies within the Austin metropolitan area...

The surface-water resources of the United States, the focal point for this National Water Summary, are extensively developed and managed to provide water supplies, hydroelectric power, navigation, recreational opportunities, and sufficient instream flows to maintain fish and wildlife habitats and adequate water quality. Surface water represents 77 percent of the Nation's total freshwater

Castro and and Parmer Counties, with an estimated 700,000 acres under irrigation, are two of the leading agricultural counties in Texas. This report summarizes irrigation data collected by the U.S. Geological Survey at 64 randomly-selected sites as part of a study to better define the relationship between pumpage for irrigation and return flow to the High Plains aquifer from applied...
