Hydrologic considerations in dewatering and refilling Lake Carlton, Orange and Lake Counties, Florida
Warren Anderson, G.H. Hughes
1977, Water-Resources Investigations Report 76-131
Lake Carlton straddles the line between Lake and Orange Counties in central Florida. The 382-acre (155-hectare) lake is highly eutrophic and subject to virtually perpetual algal blooms. The Florida Game and Fresh Water Fish Commission has proposed to restore the lake to a less eutrophic state by dewatering the lake...

H. B. Counts, R.E. Krause
1977, Water-Resources Investigations Report 76-133
A digital model of the principal artesian aquifer has been developed for the Savannah, Georgia, area. The model simulates the response of the aquifer system to various hydrologic stresses. Model results of the water levels and water-level changes are shown on maps. Computations may be extended in time, indicating changes...

Combined Ice and Water Balances of Maclure Glacier, California, South Cascade Glacier, Washington, and Wolverine and Gulkana Glaciers, Alaska, 1967 Hydrologic Year
Wendell V. Tangborn, Lawrence R. Mayo, David R. Scully, Robert M. Krimmel
1977, Professional Paper 715-B
Combined ice and water balances were measured in the 1967 hydrologic year (October 1-September 30) on four glaciers in western North America ranging in latitude from 37 deg to 63 deg N. This hydrologic year was characterized by heavier than normal winter precipitation in California and Washington and abnormally dry...
Ground-water appraisal of the Pineland Sands area, central Minnesota
J. O. Helgesen
1977, Water-Resources Investigations Report 77-102
The Pineland Sands area consists of 770 square miles of surficial glacial outwash, which is undergoing increasing ground-water development for irrigation. The aquifer material is commonly very fine sand to fine gravel, and grain size generally increases from south to north. Thickness, transmissivity, and theoretical well yields are highest in...
Water resources in western Cortland County, New York: hydrologic data for 1972-75 and progress report
Harold L. Shindel, William Buller, William H. Johnston
1977, Open-File Report 77-525
Basic data on the surface water, ground water, and water quality of Cortland County, New York, are presented with a short explanatory text. Seepage investigations showed that during periods of base flow, the surface-water regime cannot be predicted on the basis of flow-duration figures alone. The investigations also indicate that...
Evaluation of ground-water quality in the Santa Maria Valley, California
Jerry L. Hughes
1977, Water-Resources Investigations Report 76-128
The quality and quantity of recharge to the Santa Maria Valley groundwater basin from natural sources, point sources, and agriculture were evaluated. The results are expressed in terms of a hydrologic budget, a solute balance, and maps showing the distribution of selected chemical constituents in ground water. Point sources of...
Assessment of increased thermal activity at Mount Baker, Washington, March 1975-March 1976
David Frank, Mark Frederick Meier, Donald A. Swanson, James W. with contributions by Babcock, Marvin O. Fretwell, Stephen D. Malone, Charles L. Rosenfeld, Ronald L. Shreve, Ray E. Wilcox
1977, Professional Paper 1022-A
In March 1975 Mount Baker showed a large increase in thermal emission, which has persisted for more than 1 year. Fumarole ejecta accompanied the thermal activity from March to September, but the ejecta had no constituents that suggest a magmatic source. Estimates of that part of the total heat flux...

Maps showing ground-water conditions in the southern part of the Black Mesa area, Navajo, Apache, and Coconino Counties, Arizona, 1976
Gary W. Levings, C. D. Farrar
1977, Water-Resources Investigations Report 77-41
The southern part of the Black Mesa area includes about 2,500 mi2 in northeastern Arizona and is entirely in the Navajo and Hopi Indian Reservations. The main source of water is the ground water in the several aquifers that are made up of one or more formations. The aquifers are...

Technique for estimating depth of 100-year floods in Tennessee
Charles R. Gamble, James G. Lewis
1977, Open-File Report 77-668
Preface: A method is presented for estimating the depth of the loo-year flood in four hydrologic areas in Tennessee. Depths at 151 gaging stations on streams that were not significantly affected by man made changes were related to basin characteristics by multiple regression techniques. Equations derived from the analysis can...

The part of the Arctic coast of Alaska between the Colville River and the Canadian boundary was visited in April, August, and November 1975. The study area is characterized by its cold climate and is largely uninhabited, but oil and gas discoveries have spurred development of parts of the area....
Analog-model analysis of regional three-dimensional flow in the ground-water reservoir of Long Island, New York
Rufus T. Getzen
1977, Professional Paper 982
A three-dimensional analog model of the ground-water system beneath Long Island, N.Y., provides a practical means for studying anisotropic flow on a regional scale. Constructional and operational techniques influence the simulation almost as much as model design does. Usefulness and accuracy of the model depend on (1) inherent and practical...
