Evaluation of the use of remote-sensing data to identify crop types and estimate irrigated acreage, Uvalde and Medina counties, Texas, 1989 Evaluation of the use of remote-sensing data to identify crop types and estimate irrigated acreage, Uvalde and Medina counties, Texas, 1989
Remote-sensing data were used to estimate that 190,000 acre-feet of water was pumped from the Edwards aquifer in 1989 to irrigate crops in Uvalde and Medina Counties. Landsat digital satellite images for March and July 1989 were combined and classified to identify the areas of crops irrigated with water from the Edwards aquifer in the two counties. Normalized difference, the difference...

Selenium and other elements in freshwater fishes from the irrigated San Joaquin Valley, California Selenium and other elements in freshwater fishes from the irrigated San Joaquin Valley, California
Arsenic (As), chromium (Cr), mercury (Hg), and selenium (Se) were measured in composite whole-body samples of five fishes — bluegill (Lepomis macrochirus), common carp (Cyprinus carpio), mosquitofish (Gambusia affinis), largemouth bass (Micropterus salmoides), and Sacramento blackfish (Orthodon microlepidotus) — from the San Joaquin River system to determine if concentrations were...

Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1991-92 in Fort Bend County and adjacent areas, Texas Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1991-92 in Fort Bend County and adjacent areas, Texas
This report was prepared in cooperation with the Fort Bend Subsidence District, and presents data on water-level changes during 1991-92 in the Chicot and Evangeline aquifer (fig. 1-2) in Fort Bend County. Water-level change maps were prepared previously by Locke (1990),and Locke and Barbie (1991), for both aquifers, and by Wesselman (1972) for the Chicot aquifer.

Availability and quality of water from the alluvial, glacial-drift, and Dakota aquifers and water use in southwest Iowa Availability and quality of water from the alluvial, glacial-drift, and Dakota aquifers and water use in southwest Iowa
A ground-water resources investigation was conducted in southwest Iowa to describe the availability, quality, and use of water from the alluvial, glacial-drift, and Dakota aquifers in a nine-county area. Historical water quality was examined for each aquifer, and water samples were collected for major ions, trace metals, radionuclides, and selected pesticides. Selected aspects of surface...

Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990 Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area. Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin. Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a freshwater supply for some municipalities in the area. Water in the San...

The ground-water-level monitoring network in Iowa The ground-water-level monitoring network in Iowa
The ground-water-level monitoring network in Iowa consists of 202 wells completed in the principal bedrock and surficial aquifers that supply ground water to numerous users throughout the State. The bedrock aquifers include the Cambrian-Ordovician aquifer system, the Silurian-Devonian aquifer, the Mississippian aquifer, localized Pennsylvanian aquifers, and the Dakota aquifer. The...
