Geology and hydrology of the Onondaga aquifer in eastern Erie County, New York, with emphasis on ground-water-level declines since 1982
W. W. Staubitz, Todd S. Miller
1987, Water-Resources Investigations Report 86-4317
The Onondaga aquifer is a nearly flat-lying, 25- to 110-foot-thick, cherty limestone with moderately developed karst features such as sinkholes, disappearing streams, and solution-widened joints. Most groundwater moves through solution-widened bedding planes, although some moves through vertical joints. The yield of water from 42 wells ranges from 3 to 100...
Reconnaissance of water quality in the High Plains Aquifer beneath agricultural lands, south-central Kansas
L.E. Stullken, J. K. Stamer, J. E. Carr
1987, Water-Resources Investigations Report 87-4003
The High Plains of western Kansas was one of 14 areas selected for preliminary groundwater quality reconnaissance by the U.S. Geological Survey 's Toxic Waste--Groundwater Contamination Program. The specific objective was to evaluate the effects of land used for agriculture (irrigated cropland and non-irrigated rangeland) on the water in the...
Water-resources activities of the U.S. Geological Survey in North Dakota, fiscal year 1986
1987, Open-File Report 87-530
This report was prepared to inform interested Federal, State, and local agencies and private individuals of the activities of the Water Resources Division in the State. All ongoing water-resources projects in North Dakota in fiscal year 1986 are listed. Information on each project includes objectives, approach, progress in 1985, plans...
Vertical profiles of velocity and suspended sediment in streams near Mount St. Helens, Washington
R.L. Dinehart
1987, Open-File Report 87-377
Vertical profiles of high suspended-sediment concentrations and high velocities in stream near Mount St. Helens were measured between January 1981 and May 1986 at seven gaging stations. Data-collection methods are described and the numerical data are tabulated and plotted. Values for the exponent of the sediment-distribution equation were computed for...
Ground-water hydrology of the Toppenish Creek basin, Yakima Indian Reservation, Washington
J.A. Skrivan
1987, Water-Resources Investigations Report 82-4010
A groundwater flow model was constructed for the Toppenish Creek basin aquifer system in eastern Washington. Flow was simulated in three aquifer units: (1) the confined old valley fill and shallow basalt (unit 2); (2) the underlying primary basalt (unit 3); and (3) the deep basalt (unit 4). Water levels...
Chemical quality of precipitation at Greenville, Maine
J.A. Smath, T.L. Potter
1987, Water-Resources Investigations Report 86-4037
Weekly composite precipitation samples were collected at a rural site located in Greenville, Maine for analysis of trace metals and organic compounds. Samples collected during February 1982, through May 1984, were analyzed for cadmium, chromium, copper, lead, mercury, nickel, and zinc and during February 1982, through March 1983, for chlorinated...
Preliminary surficial geology map of the Cheyenne urban area, Laramie County, Wyoming
M. E. Cooley
1987, Open-File Report 87-559
The geologic map of the Cheyenne Urban Area shows the following elements: (1) artificial fill at miscellaneous sites; (2) artificial fill in areas of large residential developments constructed since 1945; (3) artificial fill in areas of extensive construction activity; (4) undifferentiated alluvium (holocene); (5) terrace alluvium (holocene); (6) alluvial fan...

R. E. Helm
R. E. Helm, editor(s)
1987, Open-File Report 87-475
The U.S. Geological Survey 's water-resources activities in Pennsylvania are described. Some activities are topics of general interest to the water resources community while others are related to current water issues. The report also describes the mission of the Water Resources Division of the U. S. Geological Survey, and program...
Hydrology of the U.S. Army Pinon Canyon maneuver site, Las Animas County, Colorado
Paul Von Guerard, P.O. Abbott, Raymond C. Nickless
1987, Water-Resources Investigations Report 87-4227
The U.S. Department of the Army (Fort Carson Military Reservation) has acquired 381 sq mi of semiarid rangeland in southeastern Colorado for mechanized military maneuvers. The study area, known as the Pinon Canyon Maneuver Site, drains into the Purgatoire River, a major tributary of the upper Arkansas River. A multidisciplined...
