Water resources near Dillingham in the Bristol Bay Area, Alaska
R. L. Glass
1987, Water-Resources Investigations Report 87-4141
Dillingham, the largest community in the Bristol Bay area of Alaska, lies near the confluence of the Wood and Nushagak Rivers. Mean annual discharges for the Wood and Nushagak Rivers are 4,824 and 22,650 cu ft/sec. Flows generally are greatest in May through July and lowest in January through April....
Seismicity map of the state of Louisiana
Carl W. Stover, B. Glen Reagor, S. T. Algermissen
1987, Miscellaneous Field Studies Map 1081
This map is one of a series of seismicity maps produced by the U.S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000.  This map shows only those earthquakes with epicenters located within the boundaries of Louisiana, even though earthquakes in...
Hydrologic unit maps
Paul R. Seaber, F. Paul Kapinos, George L. Knapp
1987, Water Supply Paper 2294
A set of maps depicting approved boundaries of, and numerical codes for, river-basin units of the United States has been developed by the U.S . Geological Survey. These 'Hydrologic Unit Maps' are four-color maps that present information on drainage, culture, hydrography, and hydrologic boundaries and codes of (1) the 21...
Streamflow characteristics of the Colorado River Basin in Utah through September 1981
R.C. Christensen, E.B. Johnson, G.G. Plantz
1987, Open-File Report 85-421
 This report summarizes discharge data and other streamflow characteristics developed from gag ing-station records collected through September 1981 at 337 stations in the Colorado River Basin in Utah. Data also are included for 14 stations in adjacent areas of the bordering states of Arizona, Colorado, and Wyoming (fig. 1). The...
Simulation of flood hydrographs for Georgia streams
Ernest J. Inman
1987, Water Supply Paper 2317
Flood hydrographs are needed for the design of many highway drainage structures and embankments. A method for simulating these flood hydrographs at ungaged sites in Georgia is presented in this report. The O'Donnell method was used to compute unit hydrographs and lagtimes for 355 floods at 80 gaging stations. An...
A review of surface-water sediment fractions and their interactions with persistent manmade organic compounds
P.J. Witkowski, J. A. Smith, T. V. Fusillo, C. T. Chiou
1987, Circular 993
This paper reviews the suspended and surficial sediment fractions and their interactions with manmade organic compounds. The objective of this review is to isolate and describe those contaminant and sediment properties that contribute to the persistence of organic compounds in surface-water systems. Most persistent, nonionic organic contaminants, such as the...
Water resources data for Mississippi, water year 1985
E.J. Tharpe, M.L. Plunkett, F. Morris, W. T. Oakley
1987, Water Data Report MS-85-1
Water resources data for the 1985 water year for Mississippi 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-water wells. This report contains records of water discharge at 71 gaging stations;...
Analysis of surface-water data network in Kansas for effectiveness in providing regional streamflow information; with a section on theory and application of generalized least squares
K.D. Medina, Gary D. Tasker
1987, Water Supply Paper 2303
This report documents the results of an analysis of the surface-water data network in Kansas for its effectiveness in providing regional streamflow information. The network was analyzed using generalized least squares regression. The correlation and time-sampling error of the streamflow characteristic are considered in the generalized least squares method. Unregulated...
Relations between quality of urban runoff and quality of Lake Ellyn at Glen Ellyn, Illinois
Robert G. Striegl, Ellen A. Cowan
1987, Water Supply Paper 2301
Comparison of flow and chemical data collected at the principal inlet and at the outlets of Lake Ellynman urban lake in the Chicago metropolitan are--shows that detention storage alters the discharge and the quality of urban runoff. Peak water discharge and variation in the concentration of constituents transported by the...
Prediction of the effects of mine dewatering on four lakes near Crandon, Wisconsin, by use of a water-budget model
William R. Krug, Nile A. Ostenso, J. T. Krohelski
1987, Open-File Report 87-471
The effects of dewatering a proposed zinc and copper mine on water levels of four lakes near Crandon, Wisconsin, were predicted by use of a digital water-budget model of the lakes. The average lake-stage reduction predicted by the model for expected ground-water levels after mine dewatering ranged from 0.21 feet for...
Index to limnological data for southcentral Alaska Lakes
M.A. Maurer, P. F. Woods
1987, Open-File Report 87-529
South-central Alaska lakes are a valuable natural resource and provide a variety of recreational opportunities to the public. Lakeside development has increased significantly in the past 10 years and several south-central Alaskan lakes have documented pollution problems. Cultural eutrophication, the process by which man-induced nutrient loading to a lake results...
