Climatic and lake temperature data for Wetland P1, Cottonwood Lake Area, Stutsman County, North Dakota, 1982-87
Renee S. Parkhurst, A.M. Sturrock, D.O. Rosenberry, T. C. Winter
1995, Open-File Report 94-546
Research on the hydrology of Wetland P1 and the Cottonwood Lake Area includes the study of evaporation. Presented here in a graphical format are those data collected during the open-water seasons of 1982-87 that were needed for energy- budget and mass-transfer evaporation studies. The data include air temperatures, water surface...
Nonpoint sources of pesticides in the San Joaquin River, California; input from winter storms, 1992-93
Joseph L. Domagalski
1995, Open-File Report 95-165
Organophosphate insecticides, including chlor- pyrifos, diazinon, and methidathion, are applied to dormant orchards in the San Joaquin Valley, California, during late December through January. This time frame coincides with the period of heaviest rainfall in the valley, and rainfall mobilizes a portion of these pesticides from the orchards. The pesticides...
Field screening of water quality, bottom sediment, and biota associated with irrigation drainage, Wind River Indian Reservation, Wyoming, 1992-93

1995, Open-File Report 95-121
Physical, chemical, and biological data were collected in 1992-93 from irrigation drainage areas and wetlands of the Wind River Federal Irrigation Project, Wind River Indian Reservation, Wyoming. Most samples collected had concentrations of chemical constituents less than the established levels of concern for water, bottom sediment, and biota. In the...
Water-related scientific activities of the U.S. Geological Survey in Nevada, fiscal years 1993-94
M. Teresa Foglesong (compiler)
1995, Open-File Report 95-126
The U.S. Geological Survey has been collecting water-resources data in Nevada since 1890. Most of the projects that constitute the current Nevada District program can be classified as either basic- data acquisition (about 25 percent) or hydrologic interpretation (about 75 percent). About 39 percent of the activities are supported by...
Hydrogeologic data for the northern Rocky Mountains intermontane basins, Montana
DeAnn M. Dutton, Sean M. Lawlor, D.W. Briar, R.E. Tresch
1995, Open-File Report 95-143
The U.S. Geological Survey began a Regional Aquifer- System Analysis of the Northern Rocky Mountains Intermontane Basins of western Montana and central and central and northern Idaho in 1990 to establish a regional framework of information for aquifers in 54 intermontane basins in an area of about 77,500 square miles....
Effect of the Cedar River on the quality of the ground-water supply for Cedar Rapids, Iowa
P.M. Schulmeyer
1995, Water-Resources Investigations Report 94-4211
The Surface Water Treatment Rule under the 1986 Amendment to the Safe Drinking Water Act requires that public-water supplies be evaluated for susceptibility to surface-water effects. The alluvial aquifer adjacent to the Cedar River is evaluated for biogenic material and monitored for selected water-quality properties and constituents to determine the...
Geohydrology and water quality of stratified-drift aquifers in the Contoocook River basin, south-central New Hampshire
P. T. Harte, William Johnson
1995, Water-Resources Investigations Report 92-4154
Stratified-drift aquifers discontinuously underlie 121 mi2 (square miles) of the Contoocook River Basin, which has a total drainage area of 776 mi2. Maps of these aquifers, showing water-table configurations, saturated thicknesses, and transmissivities were prepared from well and test-hole data and seismic-refraction profiles. The distribution of stratified-drift aquifers is largely...
Summary of sediment resuspension monitoring activities, Old Tampa Bay and Hillsborough Bay, Florida, 1988-91
V.A. Levesque, D. H. Schoellhamer
1995, Water-Resources Investigations Report 94-4081
Sediment resuspension was studied in Old Tampa BaY, the northwestern subembayment of Tampa Bay, and in Hillsborough Bay, the northeastern subembayment of Tampa Bay located along the coast of west-central Florida. Electromagnetic current meters, optical backscatterance sensors, and water samples were used to collect sediment resuspension data at several study...
Water-quality assessment of the Kentucky River Basin, Kentucky: Distribution of metals and other trace elements in sediment and water, 1987-90
Stephen D. Porter, Kevin D. White, J. R. Clark
1995, Water-Resources Investigations Report 94-4134
The U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program is designed to provide a nationally consistent description of the current status of water quality, to define water-quality trends, and to relate past and present water-quality conditions to natural features, uses of land and water, and other water-quality effects from...
A hydrogeologic approach to identify land uses that overlie ground-water flow paths, Broward County, Florida
R.S. Sonenshein
1995, Water-Resources Investigations Report 94-4167
A hydrogeologic approach that integrates the use of hydrogeologic and spatial tools aids in the identification of land uses that overlie ground- water flow paths and permits a better understanding of ground-water flow systems. A mathematical model was used to simulate the ground-water flow system in Broward County, particle-tracking software...
Database of well and areal data, South San Francisco Bay and Peninsula area, California
D.A. Leighton, J.L. Fio, L.F. Metzger
1995, Water-Resources Investigations Report 94-4151
A database was developed to organize and manage data compiled for a regional assessment of geohydrologic and water-quality conditions in the south San Francisco Bay and Peninsula area in California. Available data provided by local, State, and Federal agencies and private consultants was utilized in the assessment. The database consists...
A feasibility study to estimate minimum surface-casing depths of oil and gas wells to prevent ground-water contamination in four areas of western Pennsylvania
T. F. Buckwalter, P. J. Squillace
1995, Water-Resources Investigations Report 87-4136
Hydrologic data were evaluated from four areas of western Pennsylvania to estimate the minimum depth of well surface casing needed to prevent contamination of most of the fresh gr6unct-water resources by oil and gas wells. The areas are representative of the different types of oil and gas activities and of...
Estimated use of water in the New England States, 1990
B.A. Korzendorfer, M.A. Horn
1995, Water-Resources Investigations Report 94-4252
Data on freshwater withdrawals in 1990 were compiled for the New England States. An estimated 4,160 Mgal/d (million gallons per day) of freshwater was withdrawn in 1990 in the six States. Of this total, 1,430 Mgal/d was withdrawn by public suppliers and delivered to users, and 2,720 Mgal/d was withdrawn...

A. C. Gellis
1995, Water-Resources Investigations Report 94-4205
Areas of the Petroglyph National Monument, specifically those located along the West Mesa escarpment, are being affected by erosion and gullying. A reconnaissance along the 17-mile-long escarpment identified 50 gullies. The gullies were given a qualitative ranking of Class I, least erosion, to Class IV, highest erosion. Of the 50...
