Lithium in the brines of Fish Lake Valley and Columbus Salt Marsh, Nevada
C. L. Smith, Allen L. Meier, H.D. Downey
1977, Open-File Report 77-54
Analyses of waters-from springs in Nevada have led to the identification of an area containing anomalous amounts of lithium northwest of the Clayton Valley-area. Fish Lake Valley and Columbus Salt Marsh contain waters having, relatively high lithium and potassium concentrations. At least a part of these waters is probably derived...
Application of remotely sensed land-use information to improve estimates of streamflow characteristics
Edward J. Pluhowski
1977, Open-File Report 77-632
Land-use data derived from high-altitude photography and satellite imagery are presented for 49 basins in Delaware, and eastern Maryland and Virginia. Based on 1:100,000 scale maps from high-altitude photography, basin land cover was extracted at the generalized Level I and the more detailed Level II classification categories. Level I land-use...
Preliminary geomagnetic data, College Observatory, Fairbanks, Alaska: January 1977
J.B. Townshend, J.E. Papp, M.J. Moorman, C.E. Deadmon, S.P. Tilton
1977, Open-File Report 77-300-A
The preliminary geomagnetic data included here is made available to scientific personnel and organizations, as part of a cooperative effort and on a data exchange basis because of the early need by some users. To avoid delay, all of the data is copied from original forms processed at the observatory;...
Analysis of bottom material from the Willamette River, Portland Harbor, Oregon
Stuart W. McKenzie
1977, Open-File Report 77-740
The bottom material of the Willamette River, Portland Harbor, was sampled in duplicate on February 1, 1977. Results are reported on the following analyses of the material: immediate and long-term oxygen demand; particle size; percent moisture; residue, loss on ignition; and chemical....
Albuquerque Basin seismic network
Lawrence H. Jaksha, Jerry Locke, J.B. Thompson, Alvin Garcia
1977, Open-File Report 77-865
The U.S. Geological Survey has recently completed the installation of a seismic network around the Albuquerque Basin in New Mexico. The network consists of two seismometer arrays, a thirteen-station array monitoring an area of approximately 28,000 km 2 and an eight-element array monitoring the area immediately adjacent to the Albuquerque...
Preliminary flood-frequency relations for urban streams, Metropolitan Atlanta, Georgia
Harold G. Golden
1977, Water-Resources Investigations Report 77-57
A method is presented for estimating the magnitude and frequency of floods for urban streams in metropolitan Atlanta. The method is based on adjustments to the natural stream flood-frequency and rainfall-frequency characteristics of the local area as defined by urban flood studies in other areas.The effects of urbanization on flood-peak...
Ground-water appraisal of the Pineland Sands area, central Minnesota
J. O. Helgesen
1977, Water-Resources Investigations Report 77-102
The Pineland Sands area consists of 770 square miles of surficial glacial outwash, which is undergoing increasing ground-water development for irrigation. The aquifer material is commonly very fine sand to fine gravel, and grain size generally increases from south to north. Thickness, transmissivity, and theoretical well yields are highest in...
Water resources data for Florida, water year 1976; Volume 4. Northwest Florida--surface water, ground water, and quality of water
Water Resources Division, U.S. Geological Survey
1977, Water Data Report FL-76-4
Water resources data for the 1976 water year for northwest Florida consist of records of stage, discharge, and water quality of streams; elevation and water quality of lakes and reservoirs; water-levels and water quality of wells; and discharge and water quality of springs. Additional water data were collected at various...
