Hydrologic and morphologic changes in channels of the Platte River basin: A historical perspective
T.R. Eschner, R. F. Hadley, K.D. Crowley
1981, Open-File Report 81-1125
The channels of the Platte River and its major tributaries, the South Platte and North Platte Rivers in Colorado, Wyoming, and Nebraska, have undergone major changes in hydrologic regime and morphology since 1860. These changes are attributed here to agricultural, municipal, and industrial water use.Although water-resource development varied temporally throughout...
Hydrologic reconnaissance of the Noatak River basin, Alaska, 1978
Joseph M. Childers, Donald R. Kernodle
1981, Open-File Report 81-1005
Hydrologic data were collected in 1978 described water resources of the Noatak River basin, Alaska. Streamflow varies seasonally. No flow was observed from the upper part of the basin in late winter (April). In the lower part of the basin springs support perennial flow in the Kugururok River and downstream...
A summary of phosphate-rock resources of the United States-an analysis of past estimates
James Bachelder Cathcart, Richard Porter Sheldon, Robert A. Gulbrandsen
1981, Open-File Report 81-789
The United States produced in 1980 about 54 million tons of phosphate rock, which was 40 percent of the world production. About 62 percent of this production was exported, 28 percent as phosphate rock and 34 percent is manufactured fertilizers and chemicals. The remainder was used domestically, largely (88 percent)...
Selected hydrologic and climatologic data from the Prairie Dog Creek Basin, southeastern Montana, water year 1979
Lawrence E. Cary, Joel D. Johnson
1981, Open-File Report 81-412
Hydrologic and climatologic data are being collected in a 19-square-mile (49-square-kilometer) basin in southeastern Montana to provide a base for development, calibration, and verification of a precipitation-runoff model. The study area and data-collection stations within the area are shown on a map. A summary of data collected at each station...
Wildlife survey: Cache Creek and Little Granite Creek, Bridger-Teton National Forest
Franz J. Camenzind
1981, Open-File Report 81-851
The results of the wildlife survey are drawn from 410 hours of field observations by the senior wildlife biologist and two biologist technicians, Terry Peterson and John Hoak. Additional observations were made by other project personnel, coincidental with other assigned duties, and by the senior biologist earlier in the season....
An archeological sample survey in the Cache Creek-Little Granite Creek area of the Bridger-Teton National Forest, western Wyoming
Carlos F. Caraveo, Stephen Lau
1981, Open-File Report 81-852
Archeological Services of Laramie, Wyoming, undertook a Class II archeological reconnaissance of a large tract of land in a proposed wilderness area in the Bridger-Teton National Forest. The findings were to be submitted for inclusion in an Environmental Impact Statement being assembled by Land Management Services of Jackson, Wyoming. The...
Description and preliminary interpretation of core CL-80-1, Clear Lake, Lake County, California
John D. Sims, Michael J. Rymer, James A. Perkins
1981, Open-File Report 81-751
Coring operations were conducted in the west basin of Clear Lake during July and August 1980 to produce a regional Quaternary reference section. A 177-m-long core (CL-80-1) was taken, which also augments and extends a previous study of eight shorter cores collected from Clear Lake in 1973. Core CL-80-1 was...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: November 1981
J.B. Townshend, J.E. Papp, E.A. Sauter
1981, Open-File Report 81-300-K
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;...
Sample mine-site permit application (hydrologic assessment)
William J. Herb, D.M. Brown, L.D. Carswell, P. L. Lietman
1981, Open-File Report 81-60
Hydrologic data are presented that may be useful in the permitapplication procedure required under current Office of Surface Mining regulations. The material is presented in a format which may serve as a guide for subsequent permit applications. Data on the quality and quantity of surface water and ground water for...
Changes in quality of ground water in the Lincoln area, Montana, 1974-79
Robert B. Leonard, Wayne A. Wood, Arnold J. Boettcher
1981, Open-File Report 80-1108
Water samples from representative shallow wells in the vicinity of Lincoln, Montana, were collected during March and June 1979 for analysis to evaluate changes in quality since 1974-75 and possible contamination by domestic or agricultural waste. All samples were suitable for drinking water with respect to the constituents tested. Tests...
Geochemistry of spring water, southeastern Uinta Basin, Utah and Colorado
Briant A. Kimball
1981, Water Supply Paper 2074
The chemical quality of water in the southeastern Uinta Basin, Utah and Colorado, is important to the future development of the abundant oil-shale resources of the area. This report examines the observed changes in chemistry as water circulates in both shallow and deep ground-water systems. Mass-balance and mass- transfer calculations...
Map showing bathymetry and aquatic plants of Lake Waramaug, Connecticut
Kenneth P. Kulp
1981, Open-File Report 81-477
The Bathymetry of Lake Waramaug is shown at 5-foot intervals, and the location and identification of significant concentrations of aquatic plants is indicated. The bathymetry shows the lake to be relatively steep-sided and flat-bottomed, with a maximum depth of between 40 and 45 feet. Aquatic plants were confined to the...
