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)...

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...
Percentage change in saturated thickness of the High Plains aquifer, west-central Kansas, 1950 to average 1983-85
Barbara J. Dague
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,...
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...
Generalized potentiometric surface of aquifers of Pleistocene age, Southern Louisiana, 1980
Angel Martin Jr., Charles D. Whiteman Jr.
1985, Water-Resources Investigations Report 84-4331
A map of potentiometric surface defines generalized water levels for 1980 in the Pleistocene aquifers of southern Louisiana. The map was prepared as part of the Western Gulf Coast Regional Aquifer-System Analysis study. The Pleistocene deposits in southern Louisiana consist of alternating beds of sand, gravel, silt, and clay deposited...
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...

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...
Altitude and configuration of the water table and depth to water near Cheyenne, Wyoming, May 1984
Marvin A. Crist
1985, Water-Resources Investigations Report 85-4154
Altitude and configuration of the water table and depth to water were determined for an area near the southwestern corner of Francis E. Warren Air Force Base which is adjacent to the city limits of Cheyenne, Wyoming. Water levels in the Ogallala Formation, of late Miocene age, generally are less...
Occurrence of saltwater in the alluvial aquifer in the Boeuf-Tensas Basin, Arkansas
D. J. Fitzpatrick
1985, Water-Resources Investigations Report 85-4029
The occurrence of saline water in the alluvial aquifer in the Boeuf-Tensas basin in southeastern Arkansas has been of increasing concern. A band of saline water containing chloride concentrations of greater than 50 milligrams per liter extends through the entire length of the basin. The most severely affected area is...

Seismicity map of the State of Montana
B.G. Reagor, C. W. Stover, S. T. Algermissen
1985, Miscellaneous Field Studies Map 1819
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Montana, even though earthquakes...
Potentiometric surfaces of the coastal plain aquifers of South Carolina prior to development
Walter R. Aucott, Gary K. Speiran
1985, Water-Resources Investigations Report 84-4208
Characteristics of the Coastal Plains aquifers of South Carolina are being studied as a part of the Regional Aquifer Systems Analysis program of the U.S. Geological Survey. A framework has been developed to best represent the hydrology of the Coastal Plain aquifers by dividing them into a system of five...

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...

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...
Hydrology of Lake Placid and adjacent area, Highlands County, Florida
D. Briane Adams, Yvonne E. Stoker
1985, Water-Resources Investigations Report 84-4149
The study conducted during 1982-83, documents hydrologic conditions in Lake Placid and surrounding areas of Florida. Lake-stage data indicate that the 2- to 50-year flood stage ranges from 93.9 to 96.2 ft. Lake stage is reflected by annual departure of precipitation of the previous year from long-term average. A bathymetric...
