Fluctuations of ground-water levels in Lee County, Florida, in 1975 water year
T.H. O’Donnell
1977, Open-File Report 76-854
During the 1975 water year, rainfall was about average at Page Field, Florida, and from 20-25 percent below average at Lehigh Acres and Sanibel Island. Water levels were monitored in 57 observation wells in Lee County, Florida. Of the 23 wells that tap the water-table aquifer, one record high and...
Municipal water supplies in Lee County, Florida, 1974
T.H. O’Donnell
1977, Open-File Report 77-277
In 1974 the total pumpage for Lee County, Fla., municipal supplies reached 5,700 Mgal (million gallons annually), an increase of 54 percent over 1970 levels. Pumpage from individual sources included: Caloosahatchee River, 1,312 Mgal; water-table aquifer, 2,171 Mgal; the water-bearing zone in the Tamiami Formation, 340 Mgal; the water-bearing zone...
Hydrologic changes after logging in two small Oregon coastal watersheds
David Dell Harris
1977, Water Supply Paper 2037
Effects of clearcut, cable logging on the hydrologic characteristics of a small coastal stream in Oregon indicate an average 181-percent increase in sediment yield over a 7-year postlogging period. Annual runoff and high-flow volumes increased 19 and 1.1 inches (480 and 28 mm), respectively, after logging in the watershed. Clearcutting...
Ground-water resources of Cambodia
William Charles Rasmussen, Gary M. Bradford
1977, Water Supply Paper 1608-P
Cambodia (now the Khmer Republic), in tropical, humid southeast Asia, has an area of 175,630 km and a population of about 5 million. The Mekong River, one of the world's largest rivers, flows through Cambodia. Also, the Tonle Sap (Grand Lac), a highly productive fresh-water lake, functions as a huge...
Maximum floodflows in the conterminous United States
John R. Crippen, Conrad D. Bue
1977, Water Supply Paper 1887
Peak floodflows from thousands of observation sites within the conterminous United States were studied to provide a guide for estimating potential maximum floodflows. Data were selected from 883 sites with drainage areas of less than 10,000 square miles (25,900 square kilometers) and were grouped into regional sets. Outstanding floods for...
Relation of bulk precipitation and evapotranspiration to water quality and water resources, St. Thomas, Virgin Islands
Donald George Jordan, Donald W. Fisher
1977, Water Supply Paper 1663-I
St. Thomas, Virgin Islands, lies in what can be considered a true maritime regime, being 600 miles (1000 kilometers) from the nearest continental landmass. The island is composed almost entirely of volcanic rocks mantled by a thin soil seldom more than 2 feet (60 centimeters) thick. Rainfall, averaging about 40...
Ground-water levels in the United States, 1972-74, north-central states
Water Resources Division, U.S. Geological Survey
1977, Water Supply Paper 2163
Publication of ground-water level data for the United States in water-supply papers was begun by the Geological Survey in 1935. From 1935 through 1939, a single water-supply paper for each year covering the entire nation was issued (Water-Supply Papers 777, 817, 840, 845, and 886). Since then water-supply papers have...
Current oil and gas production from North American Upper Cretaceous chalks
Peter A. Scholle
1977, Circular 767
Production of oil and natural gas from North American chalks has increased significantly during the past five years, spurred by the prolific production from North Sea chalks, as well as by higher prices and improved production technology. Chalk reservoirs have been discovered in the Gulf Coast in the Austin Group,...
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...

1977, Circular 753
This circular contains expanded abstracts for the technical papers presented at the 1977 Uranium and Thorium Research and Resources Conference, sponsored by the Branch of Uranium and Thorium Resources, U.S. Geological Survey. This Conference was held April 27 and 28, 1977, at the Colorado School of Mines, Golden. This was...
The Alaskan Mineral Resource Assessment Program; background information to accompany folio of geologic and mineral resource maps of the McCarthy Quadrangle, Alaska
E. M. MacKevett, N. R. D. Albert, D.F. Barnes, J. E. Case, Keith Robinson, D.A. Singer
1977, Circular 739
The McCarthy 1? by 3? quadrangle, in eastern south-central Alaska, contains potentially significant resources of copper and possibly of a few other commodities. This circular and a companion folio of maps represent results of integrated field and laboratory studies in the disciplines of geology, geophysics, geochemistry, and satellite imagery that...
Algal conditions and the potential for future algal problems in the Willamette River, Oregon
David A. Rickert, R.R. Petersen, S. W. McKenzie, W. G. Hines, S.A. Wille
1977, Circular 715-G
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
