Water Resources Division in the 1980's : a summary of activities and programs of the U.S. Geological Survey's Water Resources Division
Edith B. Chase, John E. Moore, David A. Rickert
1985, Circular 893
The Water Resources Division of the U.S. Geological Survey has the principal responsibility within the Federal government for providing hydrologic information and appraising the Nation's water resounds. The Geological Survey is unique among government organizations because it has neither regulatory nor developmental authority--its sole product is information that is made...
Magnitude and frequency of floods in Alabama
D.A. Olin
1985, Water-Resources Investigations Report 84-4191
Methods are presented to estimate flood magnitude for selected recurrence intervals for urban and rural streams with drainage areas from 1 to 22,000 square miles. Seven hydrologic areas were delineated and regression equations were developed for six areas. Hydrologic data could not be regionalized for the seventh area. Drainage area...
Classification of stream basins in southeastern Ohio according to extent of surface coal mining
C.J. Childress
1985, Water-Resources Investigations Report 84-4212
Water-quality data were collected from streams grenadine 35 basins in the southeaster-Ohio coal region to evaluate and categorize the effect of surface coal mining on stream quality. The study area is underlain by rocks of Pennsylvanian age, the most important coal-producing formations of which are the Allegheny and Monogahela Formations. The...
The surficial aquifer in Pinellas County, Florida
K.W. Causseaux
1985, Water-Resources Investigations Report 84-4289
The surficial aquifer in Pinellas County, Florida, contains potable water throughout most of the county and is a potential source of water to augment the public supply that is presently imported from adjacent counties. The county accounts for 38 percent of the public supply consumption of ground water in the...
Cost-effectiveness of the Federal stream-gaging program in Virginia
D.H. Carpenter
1985, Water-Resources Investigations Report 85-4345
Data uses and funding sources were identified for the 77 continuous stream gages currently being operated in Virginia by the U.S. Geological Survey with a budget of $446,000. Two stream gages were identified as not being used sufficiently to warrant continuing their operation. Operation of these stations should be considered...
Quality of ground water used for public supply in Florida, 1983-84
G. A. Irwin, R.T. Kirkland, J. B. Pruitt
1985, Open-File Report 84-804
From October 1983 through March 1984, a chemical sampling reconnaissance was made of ground water used for public supply for 91 communities throughout Florida. Public supply wells present an excellent network for collecting baseline water-quality information on the quality of ground water prior to any treatment because they are located...
The effects of ground water, slope stability, and seismic hazard on the stability of the South Fork Castle Creek blockage in the Mount St. Helens area, Washington
William Meyer, M. A. Sabol, H. X. Glicken, Barry Voight
1985, Professional Paper 1345
A slope stability analysis on the South Fork Castle Creek debris avalanche blockage, near Mount St. Helens, Washington, was conducted to determine the likelihood of mass failure of the blockage and resultant breakout of South Fork Castle Creek Lake. On the basis of material properties, groundwater levels, and seismic history...
Phase I summary and phase II plan for comparing regulated with unregulated streamflow in the Yakima River at Union Gap, Washington
C.H. Swift
1985, Water-Resources Investigations Report 83-4015
A preliminary investigation of the effects of reservoir storage and canal diversion on the flow of the Yakima River at Union Gap , Washington indicates that those effects are measurable and substantial--on the average causing a reduction of roughly one-quarter from the unregulated flow. Preliminary computations of the unregulated flow...
Chemical and biological quality of selected lakes in Ohio, 1978 and 1979
C.G. Angelo, John D. Youger
1985, Open-File Report 84-249
Twenty-eight Ohio lakes were sampled by the U.S. Geological Survey and the Ohio Environmental Protection Agency for water-quality characteristics during the spring and summer of 1978 and 1979. This report is the third in a series covering a lake-sampling program that began in 1975. Data include water-column profiles of temperature,...
Hydrogeologic data from a test well in east-central Duval County, Florida
D.P. Brown, R.A. Johnson, R.A. Broxton
1985, Open-File Report 84-802
A 2,112-foot test well was drilled in east-central Duval County, Florida, to obtain geologic, hydrologic, and water chemistry data. Drill cuttings and water samples were collected, and water-level measurements and lithologic and geophysical logs were made. Deposits to a depth of 575 feet consist of sand, clayey sand, phosphatic sandy...
