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...

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...

Tsala Apopka Lake is a series of shallow , interconnected lakes, ponds, and marshes whose water surface...
Ground-water hydrology of the Lower Milliken-Sarco-Tulucay Creeks area, Napa County, California
Michael J. Johnson
1977, Water-Resources Investigations Report 77-82
The Sonoma Volcanics are the principal water-bearing materials in the lower Milliken-Sarco-Tulucay Creeks area, which occupies about 15 square miles (39 square kilometers) in and east of Napa, Calif. The distribution and composition of these volcanic units are highly variable and complex. Within the Sonoma Volcanics the tuffs constitute the...
Hydrologic considerations associated with dredging spring ponds in Wisconsin
William J. Rose
1977, Water-Resources Investigations Report 77-18
Spring ponds (small spring-fed bodies of water) are natural features of some glaciated areas and have a continuous flow of ground water entering through their bottoms and exiting through surface outlets. Dredging has been used to restore ponds that have been filled in part or totally by sediment. The purpose 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...
