Water quality investigation of Francis Slocum Lake, Luzerne County, Pennsylvania
James L. Barker
1978, Open-File Report 78-819
This report summarizes water-quality data collected in the Francis Slocum Lake drainage basin, Pennsylvania, during an assessment from October 1976 to September 1977. Data were collected for nitrogen, phosphorus, carbon, and fecal coliform and fecal streptococcal bacteria.Results of the restricted sampling indicate that nutrient recycling within the lake is sufficient...
Directory of local assistance centers of the National Water Data Exchange (NAWDEX)
Melvin D. Edwards
1978, Open-File Report 78-162
The National Water Data Exchange (NAWDEX), managed by the U.S. Geological Survey, has established a network of Local Assistance Centers throughout the United States and Puerto Rico to assist users of water data in identifying and locating the data they need. This up-dated Directory provides the information needed to contact...
Urban storm-water-quality data, Portland, Oregon, and vicinity
Timothy L. Miller
1978, Open-File Report 78-851
Urban storm-water-quality characteristics in the metropolitan area of Portland, Oreg., and Vancouver, Wash., were determined for eight drainage basins with varying drainage areas, basin slopes, impervious areas, and land uses. Automatic water-quality samplers, rain gages, and stream gages were installed in each basin. From September 1, 1975, to June 3,...

1978, Open-File Report 78-300-A
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Map showing anomalous silver distribution in stream sediment concentrates, Hillsboro and San Lorenzo quadrangles, exclusive of the Black Range Primitive Area, Sierra and Grant Counties, New Mexico
H. V. Alminas, K. C. Watts, D. F. Siems, V. E. Kraxberger
1978, Miscellaneous Field Studies Map 900-C
This map shows the distribution of anomalous silver in the nonmagnetic (NM-1) sample fraction plotted on a base which includes sample localities, topography, and generalized geology from Hedlund (1975a, b). It is part of a series of maps for several metals that accompany this folio. Distributions of silver values are shown...
Map showing thickness of young bay mud, southern San Francisco Bay, California
