Effect of bank protection measures, Stehekin River, Chelan County, Washington
L. M. Nelson
1986, Water-Resources Investigations Report 85-4316
An investigation of the lower Stehekin River was conducted to study the effects on flood elevations and velocities from four bank protection and flood prevention measures that are being contemplated as a means of reducing erosional losses of river bank property. These measures are: bank armoring, armored revetment levees, spur...
Water resources of Yankton County, South Dakota
E. F. Bugliosi
1986, Water-Resources Investigations Report 84-4241
The major surface-water sources in Yankton County, South Dakota are Lewis and Clark Lake, Marindahl and Beaver Lakes, and the Missouri and James Rivers. The James River has an average flow of 375 cu ft/sec and the Missouri River at Yankton has an average flow of 26,410 cu ft/sec. Major...
Flood-depth frequency relations for streams in Alabama
D.A. Olin
1986, Water-Resources Investigations Report 85-4296
Equations were defined for estimating the depth of water for floods having recurrence intervals of 2, 5, 10, 25, 50, 100, and 200 years on rural and urban streams in Alabama. Multiple regression analyses were made using the ' maximum RSQUARE improvement ' procedures. The dependent variable was the flood...
Discharge ratings for control gates at Mississippi River Lock and Dam 22, Saverton, Missouri
Albert J. Heinitz
1986, Water-Resources Investigations Report 86-4137
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainted and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 22, at Saverton, Missouri, were developed from current-meter discharge measurements made in the forebays of...
Discharge ratings for control gates at Mississippi River Lock and Dam 16, Muscatine, Iowa
Albert J. Heinitz
1986, Water-Resources Investigations Report 86-4136
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the lock and dams. Discharge ratings for the gates on Lock and Dam 16, at Muscatine, Iowa, were developed from current-meter discharge measurements made in the forebays of...
Discharge ratings for control gates at Mississippi River Lock and Dam 13, Fulton, Illinois
Albert J. Heinitz
1986, Water-Resources Investigations Report 86-4134
The water level of the navigation pools on the Mississippi River are maintained by the operation of tainter and roller gates at the locks and dams. Discharge ratings for the gates on Lock and Dam 13, at Fullerton, Illinois, were developed from current-meter discharge measurements made in the forebays of...
Investigation of the need for discharge adjustments for unsteady flow at selected gaging stations on streams in Tennessee
B.L. Neely, R.H. Bingham
1986, Water-Resources Investigations Report 84-4144
Measured discharges made during rising or falling stages generally require adjustments to refine constant-stage rating curves (stage-discharge relations) for gaged sites. Measurements at 42 gaging stations on Tennessee streams were selected for adjustment. Two methods, generally accepted by the U.S. Geological Survey, were tested: (1) the slope method adjusts the...
Geochemical map of the North Fork John Day River Roadless Area, Grant County, Oregon
James G. Evans
1986, Miscellaneous Field Studies Map 1581-B
The Wilderness Act (Public Law 88-577, September 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential. Results must be made available to the public and submitted to the President and the...
Effects of organic wastes on water quality from processing of oil shale from the Green River Formation, Colorado, Utah, and Wyoming
J.A. Leenheer, T.I. Noyes
1986, Professional Paper 1338
A series of investigations were conducted during a 6-year research project to determine the nature and effects of organic wastes from processing of Green River Formation oil shale on water quality. Fifty percent of the organic compounds in two retort wastewaters were identified as various aromatic amines, mono- and dicarboxylic...
Effects of surface coal mining on suspended-sediment discharge in a small mountain watershed, Fayette County, Pennsylvania
T.M. Mastrilli, D.E. Stump
1986, Water-Resources Investigations Report 85-4093
Data collected in the upper Stony Fork basin from July 1980 to November 1981 indicate that logging operations associated with block-cut surface mining temporarily increased suspended-sediment discharge of Stony Fork. However, the strip-mining operation did not increase the suspended sediment discharges of Stony Fork because of effective sediment-control measures. These...
Effect of urban stormwater runoff on ground water beneath recharge basins on Long Island, New York
H. F. Ku, D. L. Simmons
1986, Water-Resources Investigations Report 85-4088
Urban stormwater runoff was monitored during 1980-82 to investigate the source, type, quantity, and fate of contaminants routed to the more than 3,000 recharge basins on Long Island and to determine whether this runoff might be a significant source of contamination to the groundwater reservoir. Forty-six storms were monitored at...
Reconnaissance surficial geologic map of northern Death Valley, California and Nevada
Barry Moring
1986, Miscellaneous Field Studies Map 1770
Sedimentary deposits of northern Death Valley include units of alluvial, eolian, lacustrine, and spring origin.  The alluvial deposits, which include both fan and pediment deposits, predominate.  Fan deposits are divided into four major units; locally one of these is further divided into three subunits.  Pediment deposits may be divided into...
Activities of the Water Resources Division, California District, in the 1985 fiscal year
P. W. Anttila (compiler)
1986, Open-File Report 86-244
This report summarizes the progress of water-resources studies in California by the U.S. Geological Survey during the fiscal year 1985. Much of the work was done in cooperation with the State and local agencies. Additional supporting funds were transferred from other Federal agencies or appropriated directly to the Geological Survey....
