Geology and ground-water resources of the Douglas basin, Arizona, with a section on chemical quality of the ground water
Donald Robert Coates, R.L. Cushman, James Lawrence Hatchett
1955, Water Supply Paper 1354
The Douglas basin is part of a large northwest-trending intermontane valley, known as the Sulphur Spring Valley, which lies in southeastern Arizona, and extends into northeastern Sonora, Mexico. Maturely dissected mountains rise abruptly from long alluvial slopes and culminate in peaks 3,000 to 4,000 feet above the valley floor, Bedrock...
Computations of total sediment discharge, Niobrara River near Cody, Nebraska
Bruce R. Colby, C. H. Hembree
1955, Water Supply Paper 1357
A natural chute in the Niobrara River near Cody, Nebr., constricts the flow of the river except at high stages to a narrow channel in which the turbulence is sufficient to suspend nearly the total sediment discharge. Because much of the flow originates in the sandhills area of Nebraska, the...
Water-power resources in upper Carson River basin, California - Nevada
Harold L. Pumphrey
1955, Water Supply Paper 1329-A
West Fork Carson River offers the best opportunity for power development in the Carson River basin. The Hope Valley reservoir site could be developed to provide adequate storage regulation and concentration of fall would permit utilization of 1,400 feet of head in 51h miles below the clam site, or 1,900...
Reconnaissance of geology and ground water in the lower Grand River valley, South Dakota, with a section on Chemical quality of the ground water
Paul C. Tychsen, R.C. Vorhis, Eugene R. Jochens
1955, Water Supply Paper 1298
The area described in this report is the flood plain of the Grand River and the bordering benchlands in Perkins and Corson Counties, S. Dak., from a point about 6 miles west of the town of Shadehill to the confluence of the Grand and Missouri Rivers near Mobridge. The exposed bedrock...
Preliminary geologic evaluation of the Chena area, Alaska
John R. Williams
1955, Open-File Report 55-198
It seems fitting at this session of the Alaska Science Conference, the first to be held in the Fairbanks area, to give a preliminary summary of the practical results of a geologic investigation of the Chena area east of Fairbanks. The work was done by the Geological Survey in 1950....
