Statistics of petroleum exploration in the non-Communist world outside the United States and Canada
David H. Root, Emil D. Attanasi, Robert M. Turner
1987, Circular 981
The search for petroleum has expanded to include most countries in the world. From January 1, 1950, through 1980, about 160,000 crew months were spent in geologic and geophysical exploration in a study area that includes all nonCommunist countries outside the United States and Canada. By the end of 1982,...

Effects of coal strip mining on stream water quality and biology, southwestern Washington
L. A. Fuste, D. F. Meyer
1987, Water-Resources Investigations Report 86-4056
Strip mining for coal in southwestern Washington may be affecting the water quality of streams. To investigate these possible effects, five streams were selected for study of water quality in each of the two coal bearing areas: the Centralia-Chehalis coal district, and Kelso-Castle Rock coal area. In the Centralia-Chehalis coal...
The relation of streamflow to habitat for anadromous fish in the Stillaguamish River basin, Washington
S.S. Embrey
1987, Water-Resources Investigations Report 86-4326
The techniques of Instream Flow Incremental Methodology were used to determine the habitat available over a range of simulated streamflows for anadromous fish in certain reaches of streams in the Stillaguamish River basin, Washington. The stream discharge-habitat relations were used to identify that discharge termed the optimum discharge, which provides...
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...
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...
Assessment of water resources in lead-zinc mined areas in Cherokee County, Kansas, and adjacent areas
Timothy B. Spruill
1987, Water Supply Paper 2268
A study was conducted to evaluate water-resources problems related to abandoned lead and zinc mines in Cherokee County, Kansas, and adjacent areas in Missouri and Oklahoma. Past mining activities have caused changes in the hydrogeology of the area. Lead and zinc mining has caused discontinuities and perforations in the confining...
Relations between quality of urban runoff and quality of Lake Ellyn at Glen Ellyn, Illinois
