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...
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,...
Approximate potentiometric surface for the aquifer unit A2, Southeastern Coastal Plain aquifer system of the United States, prior to development
V.A. Stricker
1985, Water-Resources Investigations Report 85-4019
A generalized potentiometric surface map prepared as part of the southeastern United States, Regional Sand Aquifer-System Analysis defines the altitude of water levels under conditions prior to development for aquifer unit A2, the upper group of aquifers in the sand aquifer system. Aquifer unit A2, consisting of lower Tertiary sands,...
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...
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...
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...
Inertial instrument system for aerial surveying
R. H. Brown, W.H. Chapman, W. F. Hanna, C.E. Mongan, J.W. Hursh
1985, Open-File Report 85-184
An inertial guidance system for aerial surveying has been developed under contract to the U.S. Geological Survey. This prototype system, known as the aerial profiling of terrain (APT) system, is designed to determine continuously the positions of points along an aircraft flight path, or the underlying terrain profile, to an...
Short-term velocity measurements at Columbia Glacier, Alaska: August-September 1984
B. H. Vaughn, C. F. Raymond, Lowell A. Rasmussen, D. S. Miller, C. A. Michaelson, M. F. Meier, R. M. Krimmel, A. G. Fountain, W. W. Dunlap, C. S. Brown
1985, Open-File Report 85-487
Ice velocity data are presented for the lower reach of Columbia Glacier, Alaska. The data span a 29 day period and contain 1,072 angle sightings from two survey stations to 22 markers placed on the ice surface, and 1,621 laser measurements of the distance to one of those markers (number...
