Map showing paleontological control of Paleozoic stratigraphy in New England
Marland P. Billings, Peter T. Lyttle
1981, Miscellaneous Field Studies Map 1302
Assignment of Phanerozoic stratigraphic units to their proper place in the geologica time scale is based primarily on paleontology.  Radiometric methods are becoming increasingly important (Naylor, 1976), particularly where paleontological data are lacking.  This map and text are concerned only with the paleontological data bearing on the Paleozoic stratigraphy of...
Mineral resource potential of the Baker-Cypress BLM Instant Study Area and Timbered Crater Forest Service Further Planning (RARE II) Areas, Modoc, Shasta, and Siskiyou Counties, California
Jocelyn A. Peterson, L.M. Martin, L. E. Esparza, Gary J. Cwick
1981, Miscellaneous Field Studies Map 1214-B
In accordance with the provisions of the Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976), the Geological Survey and the Bureau of Mines have conducted mineral surveys on certain areas, which formally had been identified as "natural" and "primitive" areas prior to November 1, 1975.The Wilderness...
Water quality of Alimagnet, Farquar, and Long Lakes in Apple Valley, Minnesota
M.R. Have, G. A. Payne, M. A. Ayers
1981, Water-Resources Investigations Report 81-40
Alimagnet, Farquar, and Long Lakes, in Apple Valley, Minnesota, were sampled from 1973-79 to determine their physical and chemical characteristics. A storm-sewer inlet to Alimagnet Lake was also sampled during two storms in 1978. The 1976-77 drought caused a more noticeable effect on the quality of the lakes than any...
Hydrologic effects of proposed changes in management practices, Winnebago Pool, Wisconsin
William R. Krug
1981, Water-Resources Investigations Report 80-107
Various changes in the management practices for the Winnebago pool have been proposed. The objectives of the proposed changes are protecting wetlands adjacent to the lakes in the pool and assuring adequate flow in the Fox River downstream from Lake Winnebago. Three proposed operation plans for the Winnebago pool were...
Characterization of floodflows along the Arkansas River without regulation by Pueblo Reservoir, Portland to John Martin Reservoir, Southeastern Colorado
John R. Little, Daniel P. Bauer
1981, Water-Resources Investigations Report 80-97
The need for a method for estimating flow characteristics of flood hydrographs between Portland, Colo., and John Martin Reservoir has been promoted with the construction of the Pueble Reservoir. To meet this need a procedure was developed for predicting floodflow peaks, traveltimes, and volumes at any point along the Arkansas...
Assessment of the Santa Margarita Sandstone as a source of drinking water for the Scotts Valley area, Santa Cruz County, California
K. S. Muir
1981, Water-Resources Investigations Report 81-6
Scotts Valley, Calif., is a rural residential area with a rapidly expanding population. Its mediterranean-type climate yields an average annual rainfall of 40 inches. The Santa Margarita Sandstone is the principal aquifer in the area, supplying about 90 percent of all water for domestic purposes. Sources of recharge for the...
Hydrologic characteristics and possible effects of surface mining in the northwestern part of West Branch Antelope Creek basin, Mercer County, North Dakota
Mark E. Crawley, Douglas G. Emerson
1981, Water-Resources Investigations Report 81-79
Lignite beds and abundant discontinuous sandstone beds of the Paleocene Sentinel Butte Member of the Fort Union Formation and sand and gravel beds in the Quarternary glaciofluvial deposits (Antelope Creek aquifer) are the most important aquifers for domestic and livestock water supplies in the West Branch Antelope Creek basin. In...
Digital models of ground-water flow in the Cape Cod aquifer system, Massachusetts
John H. Guswa, Denis R. LeBlanc
1981, Open-File Report 80-67
The Cape Cod aquifer system was simulated with three-dimensional finite-difference ground-water-flow models. Five areas were modeled to provide tools that can be used to evaluate the hydrologic impacts of regional water development and waste disposal.The model boundaries were selected to represent the natural hydrologic boundaries of the aquifer. The boundary...
