Water resources and effects of development in Hernando County, Florida
J. D. Fretwell
1985, Water-Resources Investigations Report 84-4320
In spite of the hill and valley terrain in the Brooksville Ridge area of Hernando County, Florida, little surface drainage occurs within the county. Recharge to the Floridan aquifer system occurs as infiltration of precipitation within the county or as ground-water flow from Sumter County to the east and Pasco...

J. J. Hochreiter, Jane Kozinski
1985, Water-Resources Investigations Report 85-4300
The surface water and surficial-bed material at seven stations on three streams in Logan Township, Gloucester County, New Jersey, were sampled in the fall of 1984. Samples of water were analyzed for volatile organic compounds, trace metals, and organochlorine and organophosphorous compounds. Surficial-bed material was analyzed for extractable trace metals...

K.E. Kolm
1985, Water-Resources Investigations Report 85-4021
The objective of this study was to evaluate remote sensing techniques for mapping irrigated crop types and acreages in part of the James River basin of South Dakota, using Landsat imagery. The results demonstrated that a subtraction (band 7 minus band 4) method was best for identifying the location of...
Feasibility of artificial recharge to the 800-foot sand of the Kirkwood Formation in the coastal plain near Atlantic City, New Jersey
J.E. May
1985, Water-Resources Investigations Report 85-4063
Renewed development of the Atlantic City area since the mid-1970 's has increased the demand for water. Increased pumpage from the 800-foot sand of the Kirkwood Formation has reversed an antecedent water-level recovery in this aquifer, thus reducing water in storage and increasing the potential for saltwater intrusion. Practicable approaches...

D. J. Holtschlag
1985, Water-Resources Investigations Report 85-4293
This report documents the results of a study of the cost effectiveness of the stream-gaging program in Michigan. Data uses and funding sources were identified for the 129 continuous gaging stations being operated in Michigan as of 1984. One gaging station was identified as having insufficient reason to continue its...
Sources of water and nitrogen to the Widefield Aquifer, southwestern El Paso County, Colorado
Patrick Edelmann, Doug Cain
1985, Water-Resources Investigations Report 85-4162
The Widefield aquifer near Colorado Springs, Colorado, is recharged primarily by Fountain Creek and, to a lesser extent, by infiltration and percolation of water from the land surface and from groundwater inflow. During the past 20 to 30 years, concentrations of nitrate (as nitrogen) in the Widefield aquifer have increased...
The quality of water in the principal aquifers of southwestern Washington
J.C. Ebbert, K. L. Payne
1985, Water-Resources Investigations Report 84-4093
The quality of water in major aquifers in southwestern Washington was addressed in terms of inorganic-constituent, trace-metal, and fecal-coliform concentrations. Results of this assessment indicate that the groundwater in southwestern Washington can be characterized as soft to moderately hard with a low concentration of dissolved solids. Nitrate was the only...

Marvin W. Flugrath, Freeman L. Andrews, Emma McPherson
1985, Water-Resources Investigations Report 85-4301
Thermal stratification in Lake Conroe, Texas usually begins to develop in March and persists until October. Thermal stratification has resulted in significant seasonal and areal variations in the concentrations of dissolved oxygen, dissolved iron, dissolved manganese, total inorganic nitrogen, and total phosphorus. Volume-weighted-average concentration of dissolved solids generally was < 120...
Effects of surface coal mining and reclamation on ground water in small watersheds in the Allegheny Plateau, Ohio
Michael Eberle, A. C. Razem
1985, Water-Resources Investigations Report 85-4205
The hydrologic effects of surface coal mining in unlimited areas is difficult to predict, partly because of a lack of adequate data collected before and after mining and reclamation. In order to help provide data to assess the effects of surface mining on the hydrology of small basins in the...
Transit losses and traveltimes for water-supply releases from Marion Lake during drought conditions, Cottonwood River, east-central Kansas
P. R. Jordan, R. J. Hart
1985, Water-Resources Investigations Report 85-4263
A streamflow routing model was used to calculate the transit losses and traveltimes. Channel and aquifer characteristics, and the model control parameters, were estimated from available data and then verified to the extent possible by comparing model simulated streamflow to observed streamflow at streamflow gaging stations. Transit losses and traveltimes...

D. K. Maurer
1985, Water-Resources Investigations Report 84-4202
Gravity data were obtained from 460 stations in Carson Valley, Nevada and California. The data have been interpreted to obtain a map of approximate depth to bedrock for use in a ground-water model of the valley. This map delineates the shape of the alluvium-filled basin and shows that the maximum...

1985, Water-Resources Investigations Report 85-4032
A study was made to determine the suitability of three small hydrologic subareas in San Diego County, California, for reuse of treated municipal wastewater (reclaimed water). Groundwater quality has been impacted by agricultural water use, changes in natural recharge patterns, seawater intrusion, and groundwater movement from surrounding marine sediments. Groundwater...

H.E. Johnston, D.C. Dickerman
1985, Water-Resources Investigations Report 84-4254
A glacial sand and gravel aquifer in the Chipuxet River basin of Rhode Island forms a ground-water reservoir that could yield as much as 8.6 million gallons per day to wells; however, some streams would go dry for extended periods of time. The State Water Resources Board has tested five...
Hydrogeology of the Cross Bar Ranch well-field area and projected impact of pumping, Pasco County, Florida
C. B. Hutchinson
1985, Water-Resources Investigations Report 85-4001
The hydrogeology and development of a groundwater flow model are described for a 121-square-mile area in Pasco County, Florida. The hydrogeologic framework consists of the surficial aquifer--a thin blanket of sand--and the underlying carbonates of the upper Floridian aquifer. The aquifers are separated by a leaky sand and clay confining...
Appraisal of ground-water conditions and potential for seawater intrusion at Taholah, Quinault Indian Reservation, Washington
B. W. Drost

Estimated water and nutrient inflows and outflows Lake Cochituate, eastern Massachusetts, 1977-79
F. B. Gay
1985, Water-Resources Investigations Report 84-4315
Streamflow was the major source of water and nutrients (nitrogen and phosphorus) to Lake Cochituate, followed by ground water, and then precipitation during April 1978 through March 1979. Compared to all sources during that period, streams contributed 7,217 million gallons (a little over 82 percent) of water, 63 ,000 pounds...

During the period October 1977-March 1979, four wells were added to a network of wells in central Washington State to provide information on potential sources of ground-water supplies from aquifers in the Columbia River Basalt Group and supplemental ground-water data for water-management purposes where they cannot be obtained by other...
Water resources of the Cottonwood Wash Watershed, Ute Mountain Ute Indian Reservation, southwestern Colorado
A. L. Geldon
1985, Water-Resources Investigations Report 85-4027
Cottonwood Wash, near Towaoc, Colorado, is a 16-square-mile watershed with an estimated average annual precipitation influx of 14,600 acre-feet. Most of this water is consumed by evapotranspiration. Except for snowmelt in the spring months and infrequent rain storms, all flow in the wash is from springs issuing from talus, block...
