Water quality of the Neuse River, North Carolina: Variability, pollution loads, and long-term trends
Douglas A. Harned
1980, Water-Resources Investigations Report 80-36
A water-quality study of the Neuse River, N.C., based on data collected during 1956-77 at the U.S. Geological Survey stations at Clayton and Kinston, employs statistical trend analysis techniques that provide a framework for river quality assessment. Overall, water-quality of the Neuse River is satisfactory for most uses. At Clayton,...
A comparison of analog and digital modeling techniques for simulating three-dimensional ground-water flow on Long Island, New York
Thomas E. Reilly, Arlen W. Harbaugh
1980, Water-Resources Investigations Report 80-14
A three-dimensional electric-analog model of the Long Island, NY , groundwater system constructed by the U.S. Geological Survey in the early 1970 's was used as the basis for developing a digital, three-dimensional finite-difference model. The digital model was needed to provide faster modifications and more rapid solutions to water-management...

Evaluation of water resources in the Reedsport area, Oregon
Joseph F. Rinella, F. J. Frank, A.R. Leonard
1980, Open-File Report 80-444
The water supply for the Reedsport area is obtained from Clear Lake, a 310-acre coastal lake that contains 16, 600 acre-feet of water at full-pool. The lake receives about 6,000 acre-feet of water annually from runoff and direct precipitation, and it loses about 600 acre-feet by evaporation. The 2,100 acre-feet...
Summary of regional geology, petroleum potential, resource assessment and environmental considerations for oil and gas lease sale area #56
William P. Dillon, Kim D. Klitgord, Charles K. Paull, John A. Grow, Mahlon M. Ball, Gordon Dolton, Richard B. Powers, Abdul S. Khan, Peter Popenoe, James M. Robb
1980, Open-File Report 82-398
This report summarizes our general knowledge of the petroleum potential, as well as problems and hazards associated with development of petroleum resources in the area proposed for nominations for lease sale number 56. This area includes the U.S. eastern continental margin from the North Carolina-Virginia border south to approximately Cape...

David K. Beach, James V. Trumbull
1980, Open-File Report 80-366
This marine geologic map covers the western half of the Isla Caja de Muertos shelf off the south coast of Puerto Rico. Coverage extends from Playa de Ponce on the west to Punta Petrona, near the town of Santa Isabel, on the east, a distance of 26 km. Within the...
Approximate water-level changes in wells in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas, 1977-80 and 1979-80
R.K. Gabrysch, C.E. Ranzau Jr.
1980, Open-File Report 80-337
This report, which was prepared in cooperation with the cities of Houston and Galveston, the Harris Galveston Coastal Subsidence Distract, and the Texas Department of Water Resources, presents data on water-level changes during 1977-80 and 1979-80 in the Chicot and Evangelina aquifers (figs. 1-4).  During these periods, ground water pumping...
Water resources and geology of the Los Coyotes Indian Reservation and vicinity, San Diego County, California
A.P. Ballog Jr., W. R. Moyle Jr.
1980, Open-File Report 80-960
The water resources of the Los Coyotes Indian Reservation, San Diego County, Calif., are sufficient to supply the limited domestic and stock-water needs of the present residents of the reservation. Surface-water runoff is derived from direct precipitation on the area and from intermittent spring flow. Groundwater occurs in the alluvial...
