Dissolved-oxygen and algal conditions in selected locations of the Willamette River basin, Oregon
F. A. Rinella, S. W. McKenzie, S.A. Wille
1981, Open-File Report 81-529
During July and August 1978, the U.S. Geological Survey, in cooperation with the Oregon Department of Enviromental Quality, made three intensive river-quality dissolved-oxygen studies in the upper Willamette River basin. Two studies were made on the upper Willamette River and one was made on the Santiam River, a Willamette River...
Revised techniques for estimating magnitude and frequency of floods in Montana
Charles Parrett, R. J. Omang
1981, Open-File Report 81-917
Relations for estimating the flood magnitudes for ungaged sites in Montana have been updated. The State was divided into eight regions and separate multiple-regression equations for each region were developed that relate logarithms of annual flood magnitude to logarithms of basin characteristics for exceedance probabilities of 50, 20, 10, 4,...
Plankton studies in San Francisco Bay; II, Phytoplankton abundance and species composition, July 1977-December 1979
Raymond L. J. Wong, James E. Cloern
1981, Open-File Report 81-214
Data are presented on the phytoplankton species composition and abundance in San Francisco Bay from July 1977 through December 1979. Phytoplankton identification and enumerations were made at selected stations. Sample collections were made at selected stations in the main channel of the Bay from Rio Vista on the Sacramento River...
Data from geothermal test wells near Mount Hood, Oregon
J. H. Robison, L.S. Forcella, Marshall W. Gannett
1981, Open-File Report 81-1002
This report includes well specifications, drillers ' logs, and temperature logs of geothermal test wells drilled at 7 sites near Mt. Hood, Oreg. The wells were drilled in 1979 and 1980 under contract to the U.S. Geological Survey. The project, funded by the U.S. Department of Energy, was part of...
Surficial geophysical data for two cross-valley lines in the middle Eagle River valley, Alaska
Larry L. Dearborn, Donald H. Schaefer
1981, Open-File Report 80-2000
In 1979, six electrical resistivity and four seismic refraction soundings were made in the middle reach of the Eagle River valley northeast of Anchorage, Alaska. Interpretation of the geophysical data collected indicated that depth to bedrock below the valley floor varies between about 350 and 450 feet. Two, and perhaps...
Summary of U.S. Geological Survey investigations and hydrologic conditions in southwest Florida for 1979
H.C. Rollins
1981, Open-File Report 81-78
This report summarizes the hydrologic setting and the water-resources investigations in the Southwest Florida Water management District performed by the U.S. Geological Survey, Water Resources Division, for fiscal year 1979. Hydrologic conditions in southwest Florida are described and illustrated by hydrographs of selected surface-water, ground-water, and lake-stage data-collection sites. In...
Tidal flat sediments - texture, Willapa Bay, Washington
Gary W. Hill, John L. Chin
1981, Open-File Report 81-738
The purpose of this study was to texturally characterize the sediments of the mid-estuary tidal flats between Goose Point and Pickernell Creek in Willapa Bay, Washington and to compare these flats with other flats in the estuary.The mean grain size of sediments on tidal flats in the mid-estuary are fine...
