Water-level changes 1964-71, northern High Plains of Colorado
Warren E. Hofstra, John M. Klein, Thomas J. Major
1971, Open-File Report 72-166
Ground-water withdrawals for irrigation increased from about 84,000 acre-feet to 430,000 acre-feet per year between 1960 and 1970 in the northern High Plains of Colorado, causing significant water-level declines in areas where high-capacity wells are concentrated. The number of wells increased from about 500 in 1960 to 2,560 in 1970....
Geology, hydrology, and water quality of the Tracy-Dos Palos area, San Joaquin Valley, California
W. R. Hotchkiss, G. O. Balding
1971, Open-File Report 72-169
The Tracy-Dos Palos area includes about 1,800 square miles on the northwest side of the San Joaquin Valley. The Tulare Formation of Pliocene and Pleistocene age, terrace deposits of Pleistocene age, and alluvium and flood-basin deposits of Pleistocene and Holocene age constitute the fresh ground-water reservoir Pre-Tertiary and Tertiary sedimentary...
Limnology of Oneida Lake with emphasis on factors contributing to algal blooms
Phillip E. Greeson
1971, Open-File Report 72-139
Oneida Lake is a naturally eutrophic lake that has existed for about 10,500 years. It has been in a eutrophic state for at least 350 years, and the geochemically derived dissolved materials entering the lake from the drainage basin are of sufficient quantity (449,700 tones per year) to support annual...
Hydrologic analysis of Mojave River Basin, California, using electric analog model
W. F. Hardt
1971, Open-File Report 72-157
The water needs of the Mojave River basin will increase because of population and industrial growth. The Mojave Water Agency is responsible for providing sufficient water of good quality for the full economic development of the area. The U.S. Geological Survey suggested an electric analog model of the basin as...
Influence of surface glacial deposits on streamflow characteristics
P.C. Bent
1971, Open-File Report 72-34
Streamflow characteristics at gaging stations were related by multiple regression techniques to basin and climatic characteristics and equations were developed for estimating streamflow characteristics at ungaged sites. A permeability index, based on surface geology, was used in the analysis and substantially improved the standard error of estimate as compared to...
