Washington, D.C.'s vanishing springs and waterways
Garnett P. Williams
1977, Circular 752
This paper traces the disappearance or reduction of the many prominent springs and waterways that existed in Washington, D.C. , 200 years ago. The best known springs were the Smith Springs (now under the McMillan Reservoir), the Franklin Park Springs (13th and I Streets, NW.), Gibson 's Spring (15th and...
Seismicity map of the State of Maine
Carl W. Stover, B. Glen Reagor, Barbara B. Poppe
1977, Miscellaneous Field Studies Map 845
The earthquake data for the state of Maine shown on this map and listed in table 1 was taken from the U.S. Geological Survey catalog of earthquakes (Hays, and others, 1975).  This list of earthquakes was originally compiled for use in preparing the Seismic Risk Studies in the United States...
Annual summary of ground-water conditions in Arizona, spring 1975 to spring 1976
H. M. Babcock
1977, Water-Resources Investigations Report 77-10
Two small-scale maps of Arizona show (1) pumpage of ground water by areas and (2) the status of the ground-water inventory in the State. A larger map of the State at a scale of 1:500,000 shows potential well production, depth to water in selected wells in spring 1976, and change...
Annual summary of ground-water conditions in Arizona, spring 1976 to spring 1977
H. M. Babcock
1977, Water-Resources Investigations Report 77-106
Two small-scale maps of Arizona show (1) pumpage of ground water by areas and (2) the status of the ground-water inventory in the State. The main map, which is at a scale of 1:500,000, shows potential well production, depth of water in selected wells in spring 1977, and change in...
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...
User's guide for U.S. Geological Survey rainfall-runoff models; revised 1977
Philip Hadley Carrigan Jr., David E. Bower, G.R. Dempster
1977, Open-File Report 77-884
Modified versions of the rainfall-runoff model described by Dawdy, Lichty, and Bergmann (1972) (see W72-11754) are used in the U.S. Geological Survey as a means of synthesizing flood discharges for small drainage areas. Synthesized flood discharges derived through use of long-term (60-70 year) rainfall and evaporation data, provide a more...
Interpretation of an aeromagnetic anomaly in McMullen and Live Oak counties, Texas
Joseph S. Duval, R.A. Martin
1977, Open-File Report 77-768
An anomaly about 300 gammas in amplitude has been observed in data from an aerial magnetic survey flown over parts of Duval, Live Oak, McMullen, and Webb Counties, Tex. A two-and-one-half-dimensional model was used to iterpret the data, and the anomaly is apparently caused by a large mafic body centered...
Density and porosity estimates from borehole gravity data in the Castle Pines #3, #2, and #1 water wells, Douglas County, Colorado
Keith A. Byerley, J. W. Schmoker
1977, Open-File Report 77-875
Borehole gravity surveys were carried out in the Castle Pines #3, #2, and #1 water wells using the U.S. Geological Survey-LaCoste and Romberg borehole gravity meter (McCulloh and others, 1967a; McCulloh and others, 1967b). The objectives were to estimate the density and porosity of the formations penetrated, and to determine...
Technique for estimating magnitude and frequency of floods in Illinois
George W. Curtis
1977, Water-Resources Investigations Report 77-117
A technique is presented for estimating flood magnitudes at recurrence intervals ranging from 2 to 500 years, for unregulated rural streams in Illinois, with drainage areas ranging from 0.02 to 10,000 square miles. Multiple regression analyses, using streamflow data from 241 sampling sites, were used to define the flood-frequency relationships....
Water resources data for Missouri, water year 1976
Water Resources Division, U.S. Geological Survey
1977, Water Data Report MO-76-1
Water resources data for the 1976 water year for Missouri consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water quality of ground water. This report contains discharge records for 127 gaging stations; stage records for 3 of...
