Potentiometric-surface map of the Wyodak-Anderson coal bed, Powder River structural basin, Wyoming, 1973-84
Pamela B. Daddow
1986, Water-Resources Investigations Report 85-4305
Previous water level maps of shallow aquifers in the Powder River structural basin in Wyoming were based on water levels from wells completed in different stratigraphic intervals within thick sequences of sedimentary rocks. A potentiometric surface using water levels from a single aquifer had never been mapped throughout the basin....
Hydrogeology of the eastern part of the Salt River Valley area, Maricopa and Pinal Counties, Arizona
R. L. Laney, Mary Ellen Hahn
1986, Water-Resources Investigations Report 86-4147
The Salt River Valley is a major agricultural and metropolitan area in semiarid south-central Arizona. Groundwater in the permeable sedimentary deposits underlying the area is a major water supply for agricultural, municipal, and industrial users. Groundwater levels have declined as much as 400 ft in recent years. Management of the...
Surficial geology and ground-water availability in the Allegheny River basin and part of the Lake Erie basin, New York
Michael H. Frimpter
1986, Water-Resources Investigations Report 86-4041
New York State 's need to develop a groundwater management program for protection of its aquifers led in 1985 to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation (through regional planning agencies) to publish data from previous studies. The two maps...
Ground-water availability in the Genesee River Basin, New York and Pennsylvania
John C. Kammerer, William A. Hobba Jr.
1986, Water-Resources Investigations Report 86-4048
New York State 's need to develop a groundwater management strategy for the protection of its aquifers led, in 1985, to a cooperative program between the U.S. Geological Survey and the New York State Department of Environmental Conservation, through the Genesee/Finger Lakes Regional Planning Council, to publish basinwide groundwater availability...
Artesian pressures and water quality in Paleozoic aquifers in the Ten Sleep area of the Bighorn Basin, north-central Wyoming
Maurice E. Cooley
1986, Water Supply Paper 2289
The major Paleozoic artesian aquifers, the aquifers most favorable for continued development, in the Ten Sleep area of the Bighorn Basin of Wyoming are the Tensleep Sandstone, the Madison Limestone and Bighorn Dolomite (Madison-Bighorn aquifer), and the Flathead Sandstone. The minor aquifers include the Goose Egg and Park City Formations...
Water level and saturated thickness maps of the alluvial aquifer in eastern Arkansas, 1984
Maria Plafcan, Joe Edds
1986, Water-Resources Investigations Report 86-4014
The Mississippi River Valley alluvial aquifer, is a major source of water for most of eastern Arkansas. Agriculture is largely dependent on the aquifer as approximately 3.3 billion gallon per day are withdrawn for that purpose. Much smaller withdrawals also occur for industrial, public supply, and domestic use. The purpose...
Hydrogeologic and water-quality characteristics of crystalline-rock aquifers of Archean and Proterozoic age, Minnesota
H. W. Anderson Jr.
1986, Water-Resources Investigations Report 86-4033
Five aquifers in crystalline rocks of Archean and Proterozoic age in Minnesota include in descending order the North Shore Volcanic, Sioux Quartzite, Proterozoic metasedimentary, Biwabik Iron formation and undifferentiated Precambrian aquifers. The North Shore Volcanic aquifer generally yields < 15 gal/min to wells from interflow sediments and fractures in the...
Hydrologic conditions in Connors Bog Area, Anchorage, Alaska
R. L. Glass
1986, Water-Resources Investigations Report 86-4044
Connors Bog is a wetland in Anchorage, Alaska, which provides a habitat for many wildlife species and is a popular area for driving off-road vehicles. A landfill, and residential and commercial developments are present in areas which were once wetland. The main source of water is precipitation, which averages about...
Maps showing altitude of the potentiometric surface and changes in water levels in the aquifer in the Sparta and Memphis Sands in eastern Arkansas, spring 1985
Joe Edds, D. J. Fitzpatrick
1986, Water-Resources Investigations Report 86-4084
Aquifers in the Tertiary Sparta and Memphis Sands are a major source of water supply for much of eastern and south-central Arkansas. Major withdrawals occur from the aquifer for industrial and public supply, with generally lesser but locally significant amounts withdrawn for agricultural uses. Water level data from wells tapping...
Potentiometric surface, ground-water withdrawals, and recharge area for the Nanafalia-Clayton aquifer in Alabama, fall 1982
John S. Williams, Sydney S. DeJarnette, Michael Planert
1986, Water-Resources Investigations Report 86-4119
The U.S. Geological Survey began a nationwide program in 1978, termed Regional Aquifer-System Analysis (RASA), to study a number of the major aquifer systems that provide a significant part of the country 's water supply. One of the aquifer systems chosen for study was the thick and extensive sequence of...
Data on the solute concentration within the subsurface flows of Little Lost Man Creek in response to a transport experiment, Redwood National Park, northwest California
Gary W. Zellweger, V. C. Kennedy, K.E. Bencala, R.J. Avanzino, A. P. Jackman, F.J. Triska
1986, Open-File Report 86-403-W
A solute transport experiment was conducted on a 327-m reach of Little Lost Man Creek, a small stream in Humboldt County, California. Solutes were injected for 20 days. Chloride was used as a conservative tracer; lithium, potassium, and strontium were used as reactive tracers. In addition, nitrate and phosphate were...
