Geology of the Monterey Bay region
H. Gary Greene
1977, Open-File Report 77-718
Geophysical data and sea floor samples collected from the continental shelf and slope between Ano Nuevo Point and Point Sur, California indicate that the Monterey Bay region has had a complex late Cenozoic tectonic history. Uplift and depression have produced a succession of regressive and transgressive sedimentary units, while contemporaneous...
Ground-water data for the Drewsey Resource Area, Harney and Malheur counties, Oregon
Joseph B. Gonthier, C. A. Collins, David B. Anderson
1977, Open-File Report 77-741
Appraisals of the resources of selected management areas in eastern Oregon are being made by the U.S. Bureau of Land Management. To provide needed hydrologic information the Bureau of Land Management requested the U.S. Geological Survey Water Resources Division to inventory ground-water data for the Drewsey Resource Area. Included in...
Artificial-recharge tests in Upper Black Squirrel Creek basin, Jimmy Camp Valley, and Fountain Valley, El Paso County, Colorado
P.J. Emmons
1977, Water-Resources Investigations Report 77-11
Artificial-recharge tests were conducted in the alluvium in upper Black Squirrel Creek basin, the alluvium in Jimmy Camp Valley, and in the alluvium overlying the Widefield aquifer which is located in an ancestral channel in Fountain Valley, Colo. Nine artificial-recharge pits with areas of approximately 9,200 square feet each were...
Data from geologic investigations in the Yemen Arab Republic during 1976
Maurice J. Grolier, J. A. Domenico, Mary Donato, G. Chase Tibbitts Jr., W.C. Overstreet, Mohammad Mukred Ibrahim
1977, Open-File Report 77-733
The results of semiquantitative spectrographic analyses for 31 elements in 126 specimens of rocks from the Yemen Arab Republic, collected mainly during February 1976 from the Precambrian area in the southeastern part of the country, provide background data for use in geochemical evaluation of areas potentially favorable for mineral deposits....
A synoptic survey of trace metals in bottom sediments of the Willamette River, Oregon
David A. Rickert, V. C. Kennedy, S. W. McKenzie, W. G. Hines
1977, Circular 715-F
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...
Large landslides, composed of megabreccia, interbedded in Miocene basin deposits, southeastern Arizona
Medora Louise Hooper Krieger
1977, Professional Paper 1008
The landslides in the Kearny and El Capitan Mountain quadrangles, Pinal and Gila Counties, Ariz., are tabular or lens like masses of megabreccia enclosed in Miocene basin deposits. The megabreccias within individual slide blocks are composed of pervasively brecciated Precambrian and younger formations that remain in normal stratigraphic sequence, indicating...
Sedimentation in Santa Margarita Lake, San Luis Obispo County, California
G. Douglas Glysson
1977, Water-Resources Investigations Report 77-56
The 1975 storage capacity of Santa Margarita Lake in San Luis Obispo County, Calif., was 41,400 acre-feet, a decrease of 3,400 acre-feet since 1941. Usable capacity decreased from 25,800 to 23,000 acre-feet. Long-term sediment yield for the Salinas River basin upstream from the lake was estimated at 1,150 tons per...
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...
Water-resources investigations of the U.S. Geological Survey in Colorado, fiscal year 1977
John B. Weeks, Donald E. Hillier
1977, Open-File Report 77-532
Water-resources investigations of the U.S. Geological Survey in Colorado consist of collecting water-resources data and conducting interpretive hydro-logic investigations. The water-resources data and the results of the investigations are published or released by either the U.S. Geological Survey or by cooperating agencies. This report describes the water-resources investigations in Colorado...
