An appraisal of surface-water quality in the Alameda Creek Basin, California, October 1974-June 1979
L.E. Lopp
1981, Water-Resources Investigations Report 81-46
Areal and seasonal variations in the quality of surface water in the Alameda Creek basin, California., from 1974 to 1979 were analyzed to determine the effects of wastewater discharges and imported water releases. Statistically significant differences were found among mean values of constituents in streamflow below the treated wastewater discharge...
Water-resources investigations of the U.S. Geological Survey in Arkansas, fiscal year 1981
1981, Open-File Report 81-1003
During fiscal year 1981 there were 20 water-resources investigations in progress by the Arkansas District of the U. S. Geological Survey 's Water Resources Division. Investigations that mainly involved data collection included surface-water gaging, water-level measuring, water-quality sampling, sediment sampling, and water-use inventorying. Interpretive studies included three that were principally...
Ground-water hydrology of strip-mine areas in eastern Ohio (conditions during mining of two watersheds in Coshocton and Muskingum counties)
John O. Helgesen, Allan C. Razem
1981, Open-File Report 81-913
Ground-water conditions during coal strip mining in two small watersheds are described as part of an ongoing study of effects of mining on hydrologic systems. Both watersheds were underlain by stratified sedimentary rocks containing two perched aquifers above clay beds which underlaid the major coal seams. Mining involved removing the...
Approximate ground-water-level contours, April 1981, for the Soquel-Aptos area, Santa Cruz County, California
Richard M. Bloyd
1981, Open-File Report 81-680
Ground-water levels in selected wells were measured in the Soquel-Aptos, Calif., area in April 1981. On the basis of these measurements approximate ground-water-level contours were constructed. The general direction of ground-water movement in the Soquell-Aptos area is from the ridges in the northern part of the area, toward the adjacent...
Activities in Idaho; status of projects, fiscal year 1981
L. K. Channel
1981, Open-File Report 82-169
Twenty-three projects were conducted by the Water Resources Division of the U.S. Geological Survey in Idaho during fiscal year 1981. These projects were made in cooperation with 6 State and local and 11 Federal agencies. State and local cooperative funding amounted to $720,670; Federal funding amounted to $2,437,628.Eighty-three persons were...
Use of flow-duration curves to evaluate effects of urbanization on streamflow patterns on Long Island, New York
Keith R. Prince
1981, Water-Resources Investigations Report 80-114
Streamflow patterns on Long Island, N.Y., have been changing over the last three decades in response to eastward population growth and urbanization. Flow-duration curves for nine streams in Nassau and Suffolk Counties indicate that, during this time, streams in urbanized areas have had increased peak flows and decreased base flows,...
Data file: the 1976 Atlantic Margin Coring (AMCOR) Project of the U.S. Geological Survey
Lawrence J. Poppe
Lawrence J. Poppe, editor(s)
1981, Open-File Report 81-239
In 1976, the U.S. Geological Survey conducted the Atlantic Margin Coring Project (AMCOR) to obtain information on stratigraphy, hydrology and water chemistry, mineral resources other than petroleum hydrocarbons, and geotechnical engineering properties at sites widely distributed along the Continental Shelf and Slope of the Eastern United States (Hathaway and others,...
Water-resources investigations of the U.S. Geological Survey in Colorado: fiscal year 1981
W.E. Price
1981, Open-File Report 81-150
The report provides an overview of water-resources data collection and hydrologic investigations in Colorado from October 1, 1980, to September 30, 1981. Most of the work is carried out in cooperation with 51 Federal, State, and local agencies. Data are being collected at 503 surface-water gaging stations, 161 surface-water quality...
Altitude of the water table in the alluvial and other shallow aquifers along the Colorado River near La Grange, Texas, December 1980
Paul Rettman
1981, Open-File Report 81-1063
The water-table contours on this map were constructed from water-level control derived from an inventory of springs and wells in the area, U.S. Geological Survey topographic maps, and from data presented by Rogers (1967). Because of the available water-level control and the rough terrain throughout the area, the delineation of...
Water resources data for Washington, water year 1980: Vol. 1 - Western Washington
Water Resources Division, U.S. Geological Survey
1981, Water Data Report WA-80-1
Water-resources data for the 1980 water year for Washington consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground-wells. This report, in two volumes, contains records for water discharge at 233 gaging...
Limnological and geochemical survey of Williams Lake, Hubbard County, Minnesota
J. W. LaBaugh, G.E. Groschen, Thomas C. Winter
1981, Water-Resources Investigations Report 81-41
A limnological and geochemical survey of Williams Lake, Minnesota, was made in 1979 to provide an initial interpretive description of the lake and the contiguous ground-water system. This survey was made as part of a continuing research program related to the investigation of the interaction of lakes and their contiguous...
Water-resources investigations of the U.S. Geological Survey in Kansas; fiscal years 1979 and 1980
Harold E. McGovern, L. J. Combs
1981, Open-File Report 81-348
Activities of the U.S. Geological Survey in Kansas include the systematic collection and analysis of data to describe the framework of hydrologic systems, assess the water resources, define existing or potential problems in the quantity or quality of water, and provide information for optimum development and management of resources. Streamflow...
Description and preliminary interpretation of core CL-80-2, Clear Lake, Lake County, California
John D. Sims, M. J. Rymer, James A. Perkins, L.A. Flora
1981, Open-File Report 81-1323
Coring operations in the west basin of Clear Lake produced a regional Quaternary reference section to augment and extend a previous study of cores from Clear Lake. This report concerns 165.8—m—long core CL-80-2, which was continuously cored in 8.0 m of water and has a 65.0 percent recovery. The sedinents...
