Estimated availability of water from stratified-drift aquifers in the Concord River Basin, Massachusetts
Lisa Bratton, Gene W. Parker
1995, Water-Resources Investigations Report 94-4256
The U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Management, Office of Water Resources, studied the Concord River Basin to estimate the volume of water that is available from stratified-drift aquifers. A combined hydrograph-separation and streamflow- duration-curve analysis indicates that 20.8 million cubic feet of water can...
Water withdrawals in the Black Warrior-Tombigbee basin in Alabama, 1985-87
W. S. Mooty
1995, Water-Resources Investigations Report 90-4112
Public-supply, industrial, and power generation water withdrawals were inventoried for the Black Warrior-Tombigbee basin in Alabama for 1987. A water source capacity analysis was done for each facility to assess the risk of the future water demand exceeding the capacity of the current source. Approximately 96 percent of all water...

K. H. Haag, S. D. Porter
1995, Water-Resources Investigations Report 94-4227
The U.S. Geological Survey investigated the water quality of the Kentucky River Basin in Kentucky as part of the National Water Quality Assessment program. Data collected during 1987-90 were used to describe the spatial and temporal variability of nutrients, suspended sediment, and pesticides in streams. Concentrations of phosphorus were signifi-...
Ground-water levels in and pumpage from the alluvial aquifer at Louisville, Kentucky, May 1989-May 1991
Michael D. Unthank
1995, Water-Resources Investigations Report 94-4099
Water-level data have been collected in the alluvial aquifer at Louisville, Ky., by the U.S. Geological Survey since 1943. Interpretations of these data are published periodically to update the record and help local officials manage this ground-water supply. Maps and hydrographs are presented on two sheets to aid in the...
Geographic information system data sets of hydrogeologic conditions in Pequea and Mill Creek watersheds, Pennsylvania; Part II, Hydrogeologic interpretations
Dennis J. Low, Douglas C. Chichester, Stephen J. Char
1995, Open-File Report 95-193
This report describes Geographic Information System data sets of ground-water levels, unsaturated-zone thickness, and regolith thickness in the Pequea and Mill Creek watersheds, a 210-square-mile area in Lancaster and Chester Counties, Pa. The data sets, which represent hydrogeologic interpretations, were developed by the use of ARC/INFO software during 1990-93 by...
Water quality of storm runoff and comparison of procedures for estimating storm-runoff loads, volume, event-mean concentrations, and the mean load for a storm for selected properties and constituents for Colorado Springs, southeastern Colorado, 1992
Paul Von Guerard, W. B. Weiss
1995, Water-Resources Investigations Report 94-4194
The U.S. Environmental Protection Agency requires that municipalities that have a population of 100,000 or greater obtain National Pollutant Discharge Elimination System permits to characterize the quality of their storm runoff. In 1992, the U.S. Geological Survey, in cooperation with the Colorado Springs City Engineering Division, began a study to...
Physical and chemical limnology of Ides Cove near Rochester, New York, 1970-1982
R.C. Bubeck, W. W. Staubitz, A.D. Weidemann, L.P. Spittal
1995, Water-Resources Investigations Report 92-4052
Ides Cove is a small embayment on the western shore of Irondequoit Bay near Rochester, N.Y. In 1982, alum was applied to the cove to seal the bottom sediments and thereby decrease nutrient fluxes in an effort to assess the applicability of this technique to Irondequoit Bay. Published data were...
Land use and water use in the Antelope Valley, California
William E. Templin, Steven P. Phillips, Daniel E. Cherry, Myrna L. DeBortoli, T.C. Haltom, Kelly R. McPherson, C.A. Mrozek
1995, Water-Resources Investigations Report 94-4208
Urban land use and water use in the Antelope Valley, California, have increased significantly since development of the valley began in the late 1800's.. Ground water has been a major source of water in this area because of limited local surface-water resources. Ground-water pumpage is reported to have increased from...
Subsurface recharge to the Tesuque aquifer system from selected drainage basins along the western side of the Sangre de Cristo Mountains near Santa Fe, New Mexico
Maryann Wasiolek
1995, Water-Resources Investigations Report 94-4072
Water budgets developed for basins of five streams draining the western side of the Sangre de Cristo Mountains in northern New Mexico indicate that subsurface inflow along the mountain front is recharging the Tesuque aquifer system of the Espanola Basin. Approximately 14,700 acre-feet of water per year, or 12.7 percent...
Methods for assessing channel conditions related to scour-critical conditions at bridges in Tennessee
B.A. Bryan, Andrew Simon, G.S. Outlaw, Randy Thomas
1995, Water-Resources Investigations Report 94-4229
The ability to assess quickly the potential for scour at a bridge site, to evaluate those bridges with the greatest potential for significant amounts of scour, and to then identify scour-critical structures is important for public protection and bridge maintenance planning. A bridge-scour assessment information form was developed for collecting...
Carbon sequestration in an aggrading forest ecosystem in the Southeastern USA
Thomas G. Huntington
1995, Soil Science Society of America Journal (59) 1459-1467
An analysis of C pools at the Panola Mountain Research Watershed (PMRW) near Atlanta, GA, indicates that aggrading forests in the U.S. Southeast are an important regional C sink. The forests in this area were cut in the early 1800s and the land was cultivated until the early 1900s, when...
Soil-solution chemistry in a low-elevation spruce-fir ecosystem, Howland, Maine
Ivan J. Fernandez, Gregory B. Lawrence, Yowhan Son
1995, Water, Air, & Soil Pollution (84) 129-145
Soil solutions were collected monthly by tension and zero-tension lysimeters in a low-elevation red spruce stand in east-central Maine from May 1987 through December 1992. Soil solutions collected by Oa tension lysimeters had higher concentrations of most constituents than the Oa zero-tension lysimeters. In Oa horizon soil solutions growing season...
Combined use of groundwater dating, chemical, and isotopic analyses to resolve the history and fate of nitrate contamination in two agricultural watersheds, Atlantic coastal plain, Maryland
J.K. Böhlke, J. M. Denver
1995, Water Resources Research (31) 2319-2339
The history and fate of groundwater nitrate (NO3−) contamination were compared in 2 small adjacent agricultural watersheds in the Atlantic coastal plain by combined use of chronologic (CCl2F2, 3H), chemical (dissolved solids, gases), and isotopic (δ15N,δ13C, δ34S) analyses of recharging groundwaters, discharging groundwaters, and surface waters. The results demonstrate the interactive...

Carmen A. Garcia, N.D. Hoy
1995, Open-File Report 95-185
The U.S. Geological Survey has released a listing of its reports on water resources in Florida for the period 1886-1995.

Sierra Nevada runoff into San Francisco Bay - Why has it come earlier recently?
M. D. Dettinger, D.R. Cayan, D. H. Peterson
1995, Newsletter of the Interagency Ecological Program for the Sacramento-San Joaquin Estuary (8) 1-3
By the time most of the Sierra Nevada snowpack has melted each summer, freshwater outflows from the Sacramento-San Joaquin Delta to San Francisco Bay are typically small, even after the wettest winters. These small delta outflows during the warm months (in comparison with the large flows of winter and spring)...

Ingrid M. Verstraeten, S. S. Sibray, J. C. Cannia, D. Q. Tanner
1995, Water-Resources Investigations Report 94-4057
One-hundred twenty wells completed in unconfined Quaternary alluvial, Ogallala, Arikaree, Brule fractured, sand and confined Chadron and undifferentiated Cretaceous water-bearing units were sampled in June and July 1991 to characterize the quality of ground water in the study area. More than 75 percent of the water samples had nitrate and...

1995, Water-Resources Investigations Report 94-4056
The effects of surface coal mining on the water quality, sediment discharge, and aquatic biology of streams in the Stony Fork Basin in southwestern Pennsylvania were studied from 1978 through 1985. Data were collected at five stream sites and one mine discharge site. Field data included streamflow, temperature, specific conductance,...
