Water-level maps of the Mississippi River Valley alluvial aquifer in eastern Arkansas, 1986
Maria Plafcan, Larry M. Remsing
1989, Water-Resources Investigations Report 88-4067
The Mississippi River Valley alluvial aquifer is a major source of water for irrigation in much of eastern Arkansas. Maps of the potentiometric surface, water level change, and depth to water illustrate the effects of large withdrawals for irrigation on water levels in the aquifer. The Mississippi River Valley alluvial...
Ground-water use by public-supply systems in Tennessee in 1985
Susan S. Hutson
1989, Water-Resources Investigations Report 89-4092
Public-supply groundwater withdrawal in Tennessee in 1985 totaled about 243 million gal/day, or about 54% of the total groundwater used. Most of the withdrawals were from the Tertiary Memphis Sand in Shelby County (Memphis), West Tennessee (141 million gal/day). Of the 182 public-supply systems, 32 withdrew 1 million gal/day or...
Altitude of the potentiometric surface and changes in water levels in the Sparta-Memphis aquifer in eastern and southern Arkansas, spring 1986
Joe Edds, Daniel J. Fitzpatrick
1989, Water-Resources Investigations Report 88-4042
The Sparta-Memphis aquifer is a major source of industrial and public water supplies as well as a source of water for agricultural purposes in eastern and south-central Arkansas. The potentiometric-surface map for this aquifer, compiled from wastewater level measurements made during spring 1986, indicates a generally eastward and southward hydraulic...
Potentiometric surfaces of the Mississippi River Valley alluvial aquifer in eastern Arkansas, spring 1972 and 1980
D. J. Ackerman
1989, Water-Resources Investigations Report 88-4075
Maps that show contours of the altitude of water levels for wells completed in the Mississippi River Valley alluvial aquifer in eastern Arkansas were prepared using water-level measurements made in the spring of 1972-1980. Hydrographs for selected wells are included to show trends and lack of trends in water-level changes....
Hydrogeology of the western part of the Salt River Valley area, Maricopa County, Arizona
James G. Brown, D. R. Pool
1989, Water-Resources Investigations Report 88-4202
The Salt River Valley is a major population and agricultural center of more than 3,000 mi2 in central Arizona (fig. 1). The western part of the Salt River Valley area (area of this report) covers about 1,500 mi2. The Phoenix metropolitan area with a population of more than 1.6 million...
Precipitation, streamflow, and base flow in west-central Texas, December 1974 through March 1977
Eve L. Kuniansky
1989, Water-Resources Investigations Report 88-4218
Precipitation, streamflow, and base-flow data were analyzed for December 1974 through March 1977 as a part of the Edwards-Trinity Regional Aquifer-System Analysis in west-central Texas. The period of record analyzed corresponds to the calibrating period of a digital groundwater-flow model of the aquifer system currently (1988) being developed. Precipitation at...
Hydrogeologic characteristics of the Valley-Fill aquifer in the Arkansas River valley, Crowley and Otero Counties, Colorado
Gregory A. Nelson, R. T. Hurr, John E. Moore
1989, Open-File Report 89-255
The hydrogeology of the valley-fill aquifer of the Arkansas River valley in Crowley and Otero Counties, Colorado is presented in a series of three maps. The map shows: (1) the altitude and configuration of the bedrock surface beneath the valley-fill material; (2) the altitude and configuration of the water table...
