Water-resources activities of the U.S. Geological Survey in Montana, October 1987 through September 1989
J. N. Thamke (compiler)
1989, Open-File Report 89-591
Water resources programs and activities of the U.S. Geological Survey in Montana consist principally of hydrological data collection and local, areal, or statewide hydrologic investigations. The work is supported by direct Federal funding, by transfer of funds from other Federal agencies, and by joint funding agreements with State or local...
Assessment of the potential effects of climate change on water resources of the Delaware River basin; work plan for 1988-90
M. A. Ayers, G.H. Leavesley
1989, Open-File Report 88-478
The current consensus is that some global atmospheric warming will occur as a result of increasing ' greenhouse ' gases. Water resources scientists, planners, and managers are concerned about the uncertainty associated with climatic-change effects on water supplies and what planning might be necessary to mitigate the effects. Collaborative studies...
Aquifers in Cretaceous rocks of the central Coastal Plain of North Carolina
M. D. Winner Jr., W.L. Lyke
1989, Water-Resources Investigations Report 87-4178
Aquifers in rocks of Cretaceous age are the major source of groundwater for public supplies in the central Coastal Plain. These aquifers consist of sand, gravel, and limestone beds of the Peedee, Black Creek, and the upper and lower Cape Fear aquifers, each separated by a confining unit composed of...
Summary of data pertaining to land use, rainfall, dryfall, stream discharge, and storm runoff collected as part of a study of the effects of urban runoff on Rapid Creek, Rapid City area, South Dakota
K.E. Goddard, T.K. Lockner, L.L. Harms, M.H. Smith
1989, Open-File Report 87-45
The objectives of a 3-year study of urban runoff in the Rapid City area of South Dakota were to characterize the effects of urban runoff from rainfall on the water quality of Rapid Creek, and to evaluate the effects of the runoff on the existing cold-water fishery. In order to...
Inventory of interbasin transfers of water in the western conterminous United States
H.E. Petsch Jr.
1989, Open-File Report 85-166
Information is presented on the quantity of water transferred from one river basin to another in the western conterminous United States. The information is needed by water system managers and planners to develop water budgets for major river basins, to examine the relative extent of existing interbasin transfers, and to...
Water-quality data for selected wells and drains in the Oakes study area, south-central North Dakota, December 1986 through September 1987
James D. Wald, C.S. Helgesen, M.C. Pokladnik
1989, Open-File Report 89-63
Operation of the Garrison Diversion Unit in North Dakota will divert water from the Missouri River near Lake Audubon into the upper James River basin (fig. 1). The diverted water will augment flows in the James River sufficiently to permit expanded irrigation and to provide additional water supplies for municipal...
Osmotic potential and projected drought tolerance of four phreatophytic shrub species in Owens Valley, California
Peter D. Dileanis, David P. Groeneveld
1989, Water Supply Paper 2370-D
A substantial quantity of the water used by plant communities growing on the floor of Owens Valley, California, is derived from a shallow unconfined aquifer. Fluctuations in the water table caused by ground-water withdrawal may result in periods when this water supply is not accessible to plants. The capacity of...
Estimating soil matric potential in Owens Valley, California
Stephen K. Sorenson, Reuben F. Miller, Michael R. Welch, David P. Groeneveld, Farrel A. Branson
1989, Water Supply Paper 2370-C
Much of the floor of Owens Valley, California, is covered with alkaline scrub and alkaline meadow plant communities, whose existence is dependent partly on precipitation and partly on water infiltrated into the rooting zone from the shallow water table. The extent to which these plant communities are capable of adapting...
Annual yield and selected hydrologic data for the Arkansas River Basin Compact, Arkansas-Oklahoma, 1988 water year
Martha A. Moore, T.E. Lamb, Leland D. Hauth
1989, Open-File Report 89-54
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Compact, Arkansas-Oklahoma, are given in tables. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area are also given in tabular form. Monthly, maximum, minimum, and mean discharge are shown...
Hydrologic and geochemical monitoring in Long Valley caldera, Mono County, California, 1986
C. D. Farrar, M.L. Sorey, S.A. Rojstaczer, A.C. Steinemann, M. D. Clark
1989, Water-Resources Investigations Report 89-4033
The U.S. Geological Survey continued to monitor hydrologic and geochemical conditions in the Long Valley caldera during 1986. The monitoring is directed toward detecting changes in the hydrologic system caused by tectonic or magmatic processes. Data collected during 1986 include chemical and isotopic composition of water from selected streams sites,...
Hydrology of the Goat Lake watershed, Snohomish County, Washington, 1982-87
N. P. Dion, J.C. Ebbert, J.E. Poole, B.S. Peck
1989, Water-Resources Investigations Report 88-4235
The Goat Lake watershed in Snohomish County, Washington, functions as an ' experimental watershed ' for long-term studies to determine the effects of acidic precipitation on water resources. Data have been collected there by the U.S. Geological Survey since 1982. The watershed is in a wilderness area of the...
Chemical characteristics, including stable-isotope ratios, of surface water and ground water from selected sources in and near East Fork Armells Creek basin, southeastern Montana, 1985
R. F. Ferreira, J. H. Lambing, R. E. Davis
1989, Water-Resources Investigations Report 89-4024
Water samples were collected from 29 sites to provide synoptic chemical data, including stable-isotope ratios, for an area of active surface coal mining and to explore the effectiveness of using the data to chemically distinguish water from different aquifers. Surface-water samples were collected from one spring, four sites on East...
Low-flow characteristics of streams in West Virginia
E.A. Friel, W.N. Embree, A. R. Jack, J. T. Atkins Jr.
1989, Water-Resources Investigations Report 88-4072
Low-flow characteristics of selected streams in West Virginia were determined at continuous-record and partial-record sites. Daily discharges at 100 continuous-record gaging stations on unregulated streams were used to compute selected low-flow frequency values. Estimates of low-flow frequency values at 296 partial-record sites (ones having only discharge measurements) were made using...
