Reconnaissance geologic map and mineral resource potential of the Gearhart Mountain Wilderness and Roadless Area (6225), Lake and Klamath counties, Oregon
George W. Walker, James Ridenour
1982, Miscellaneous Field Studies Map 1367
The Gearhart Mountain Wilderness, Lake and Klamath Counties, Oreg., is devoid of mines and mineral prospects and there are no known mining claims within the area. Furthermore, the results of this mineral appraisal indicate that there is little likelihood that commercial deposits of metallic minerals will be found in the...
Automation of an ion chromatograph for precipitation analysis with computerized data reduction
Arthur G. Hedley, Marvin J. Fishman
1982, Water-Resources Investigations Report 81-78
Interconnection of an ion chromatograph, an autosampler, and a computing integrator to form an analytical system for simultaneous determination of fluoride, chloride, orthophosphate, bromide, nitrate, and sulfate in precipitation samples is described. Computer programs provided with the integrator are modified to implement ionchromatographic data reduction and data storage. The liquid-flow...

Water resources data for Massachusetts and Rhode Island, water year 1981
Water Resources Division, U.S. Geological Survey
1982, Water Data Report MA-RI-81-1
Water-resources data for the 1981 water year for Massachusetts and Rhode Island consist of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 100 gaging stations, month end contents for 30 lakes and reservoirs, water quality...
Determination of ultimate carbonaceous BOD and the specific rate constant (K1)
J. K. Stamer, J. P. Bennett, Stuart W. McKenzie
1982, Open-File Report 82-645
Ultimate carbonaceous biochemical oxygen demand (BODu) and the specific rate constant (K1) at which the demand is exerted are important parameters in designing biological wastewater treatment plants and in assessing the impact of wastewater on receiving streams. An analytical method is presented which uses time-series concentrations of BOD, defined as...

Annual water-resources review, White Sands Missile Range, New Mexico
R. R. Cruz
1982, Open-File Report 82-757
Ground-water data were collected in 1981 at White Sands Missile Range in south-central New Mexico. The total amount of water pumped at White Sands Missile Range was approximately 59 million gallons less than in 1980; however the five supply wells in the Range areas adjacent to the Post Headquarters area...
An evaluation of suspended sediments and turbidity in Cow Creek, Oregon
D. A. Curtiss
1982, Open-File Report 82-364
During a 6-month period from December 1980 through May 1981, samples were collected from Cow Creek near Azalea, Oreg., and analyzed for suspended sediment, particle-size distribution, and turbidity. Of the estimated suspended-sediment discharge of 4,270 tons for the 1981 water year, 95 percent (4,050 tons) was transported during a major...

Evapotranspiration of applied water, Central Valley, California, 1957-78
Alex K. Williamson
1982, Water-Resources Investigations Report 81-45
In the Central Valley, Calif., where 57% of the 20,000 square miles of land is irrigated, ground-water recharge from agricultural lands is an important input to digital simulation models of ground-water flow. Several methods of calculating recharge were explored for the Central Valley Aquifer Project and a simplified water budget...
Aeromagnetic measurements in the Cascade Range and Modoc Plateau of northern California; report on work done from December 1, 1980, to May 31, 1981
Richard W. Couch, Michael Gemperle
1982, Open-File Report 82-933
Spectral analysis of aeromagnetic data collected over 6orth-central California during the summer of 1980 aided in determining magnetic-source bottom depths beneath the survey area. Five regions of shallow magnetic source bottom depths were detected: 1) Secret Spring Mountain and National Lava Beds Monument area, 2) the Mount Shasta area, 3)...

1982, Open-File Report 82-159
The Hyde Park landfill is a 15-acre chemical waste disposal site located north of Niagara Falls, New York. Underlying the site in descending order are: (1) low permeability glacial till, (2) a moderately permeable fractured rock aquifer--the Lockport Dolomite, and (3) a low permeability unit--the Rochester Shale. The site is...

Annual snowmelt and rainfall peak-flow data on selected foothills region streams, South Platte River, Arkansas River, and Colorado River basins, Colorado
J. G. Elliott, R.D. Jarrett, J.L. Ebling
1982, Open-File Report 82-426
Peak flows in the foothills region of Colorado are attributable to two meteorological sources--snowmelt and rainfall. As part of a study of the hydrology of foothills streams in Colorado, charts from streamflow gages on unregulated streams were examined to determined the source of peak-flow events. Snowmelt-runoff peaks were distinguished from...
