Occurrence of ground water and potential for seawater intrusion, Island County, Washington
M. A. Jones
1985, Water-Resources Investigations Report 85-4046
The data from a study of groundwater availability and quality in Island County, Washington, are presented. Increased groundwater withdrawals associated with the population increase in Island County have caused concern about groundwater availability and potential seawater intrusion. The most widely used aquifer lies near sea level. Locally, available data indicate...

1985, Water-Resources Investigations Report 85-4255
Continuing studies are being made in west-central Kansas to provide up-to-date information to aid in the management of groundwater for irrigation. This report, prepared in cooperation with the Western Kansas Groundwater Management District No. 1, presents the fifth in a series of studies that uses a statistical technique, called kriging,...
Hydrology of Lake Carroll, Hillsborough County, Florida
S.E. Henderson, R.D. Hayes, Y.E. Stoker
1985, Water-Resources Investigations Report 83-4261
Lakeshore property around Lake Carroll has undergone extensive residential development since 1960. This development increased the lake shoreline, altered surface water flow to and from the lake, and may have affected lake-stage characteristics. Some areas of the lake were dredged to provide fill material for lakefront property. Water-balance analyses for...

The hydrogeology of the 75-square mile Clifton Park suburban area near Albany, N.Y., is presented in six maps at 1:24,000 scale. The maps show: (1) location of wells and test holes; (2) bedrock topography; (3) surficial geology and geologic sections; (4) saturated thickness of the confined aquifer; (5) generalized soil...
Estimating annual suspended-sediment loads in the northern and central Appalachian Coal region
G. F. Koltun
1985, Water-Resources Investigations Report 85-4215
Multiple-regression equations were developed for estimating the annual suspended-sediment load, for a given year, from small to medium-sized basins in the northern and central parts of the Appalachian coal region. The regression analysis was performed with data for land use, basin characteristics, streamflow, rainfall, and suspended-sediment load for 15 sites...
Cost-effectiveness of the stream-gaging program in the Hawaii District
I. Matsuoka, R. Lee, W. O. Thomas
1985, Water-Resources Investigations Report 84-4126
This project documents the results of a study of the cost-effectiveness of the stream-gaging program in the Hawaii District. The stream gages in the District were divided into two groups, the State of Hawaii and the Other Pacific Areas. Data uses and funding sources were identified for the 124 continuous...
Spirit Lake dam-failure flood routing assessment
D. L. Kresch
1985, Open-File Report 82-770
Potential clear-water floodflows resulting from uncontrolled breaching by Spirit Lake of a debris dam deposited by the May 18 , 1980, eruption of Mount St. Helens, Washington, were evaluated. U.S. Geological Survey dam-break model K-634 was utilized, first to compute clear-water flood hydrographs for various hypothetical breach scenarios, and then...

Regional geochemical study of the felsic plutonic rocks in the Nuqrah Quadrangle, sheet 25E, Kingdom of Saudi Arabia
W. E. Hall, David Dellinger, G.I. Selner
1985, Open-File Report 85-25
A regional geochemical investigation of the felsic plutonic rocks of the Nuqrah quadrangle, sheet 25 E, Kingdom of Saudi Arabia, in which pan concentrates of 384 wadi samples, and 145 rock samples, were collected, defined two separate and distinct anomalous areas. One area contains Jabal Tuwalah and Jabal Awja, and...
Synopsis of saltwater intrusion in Dade County, Florida, through 1984
Howard Klein, Bradley G. Waller
1985, Water-Resources Investigations Report 85-4101
The inland position of saltwater at the base of the highly permeable limestone of the Biscayne aquifer in Dade County in 1984 is a consequence of: (1) years of adjustment to lowered water levels resulting from regional drainage for flood control and land reclamation; (2) increased freshwater withdrawals; and (3)...
Generalized potentiometric surface of the Evangeline and equivalent aquifers in Louisiana, 1980
Angel Martin Jr., Charles D. Whiteman Jr.
1985, Water-Resources Investigations Report 84-4359
A generalized potentiometric-surface map defines the altitude of water levels for 1980 in wells in the Evangeline aquifer in southwestern Louisiana and stratigraphically equivalent aquifers in southeastern Louisiana. The Evangeline and equivalent aquifers increase in thickness from zero at the northern edge of the outcrop/subcrop belt to more than 2,000...

Projected ground-water development, ground-water levels, and stream-aquifer leakage in the South Fork Solomon River Valley between Webster Reservoir and Waconda Lake, north-central Kansas, 1979-2020
Jack Kume, R. J. Lindgren, L.E. Stullken
1985, Water-Resources Investigations Report 85-4216
A two-dimensional finite difference computer model was used to project changes in the potentiometric surface, saturated thickness, and stream aquifer leakage in an alluvial aquifer resulting from four instances of projected groundwater development. The alluvial aquifer occurs in the South Fork Solomon River valley between Webster Reservoir and Waconda Lake...
Hydrology of Lake June in winter, Highlands County, South-central Florida
Roger G. Belles, Edward H. Martin
1985, Water-Resources Investigations Report 84-4303
Lake June in Winter is in central Highlands County near the town of Lake Placid in south-central Florida. Recreation and citrus-grove irrigation are the major uses of lake water. Land use around the lake is residential citrus, and undeveloped. Most of the land use in the 44-square mile lake-drainage area...
Design of a sediment data-collection program in Kansas as affected by time trends
P. R. Jordan
1985, Water-Resources Investigations Report 85-4204
Data collection programs need to be re-examined periodically in order to insure their usefulness, efficiency, and applicability. The possibility of time trends in sediment concentration, in particular, makes the examination with new statistical techniques desirable. After adjusting sediment concentrations for their relation to streamflow rates and by using a seasonal...
