Reservoir-development impacts on surface-water quantity and quality in the Yampa River basin, Colorado and Wyoming
D. Briane Adams, Daniel P. Bauer, Robert H. Dale, Timothy Doak Steele
1983, Water-Resources Investigations Report 81-30
Development of coal resources and associated economy is accelerating in the Yampa River basin in northwestern Colorado and south-central Wyoming. Increased use of the water resources of the area will have a direct impact on their quantity and quality. As part of 18 surface-water projects, 35 reservoirs have been proposed...
Hydrologic-data stations and lake levels, Kenai-Nikiski area, Alaska, 1983
Bonnie J. Bailey
1983, Open-File Report 83-938
The locations of 2 National Weather Service stations, 29 observation wells, 4 stream gages, and 12 lake-stage stations are depicted on a 1:63, 360-scale map. The periods of record and station descriptions are listed. Hydrographs depict water-level fluctuations of 12 lakes during the period 1970-1983. ...
Hydrogeologic and water-quality characteristics of the Upper Carbonate aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 84-4150
The Upper Carbonate aquifer is part of a sequence of sedimentary bedrock units deposited in Paleozoic seas that occupied a depression known as the Hollandale embayment. The aquifer is comprised of four formations, which, in ascending order, are the Galena Dolomite, Dubuque Formation, Maquoketa Shale, and Cedar Valley Limestone. Total...
Hydrogeologic and water-quality characteristics of the St. Peter aquifer, Southeast Minnesota
J. F. Ruhl, R. J. Wolf
1983, Water-Resources Investigations Report 83-4200
Quality of water in the St. Peter aquifer is generally acceptable for most uses. Sulfate concentrations increase toward the southwestern part of the aquifer because of highly mineralized leakage from overlying Cretaceous deposits. Concentrations of sodium, magnesium, and sulfate generally increase to the west, and those of calcium, bicarbonate, and...
Identification and classification of perennial streams of Arkansas
R. A. Hunrichs
1983, Water-Resources Investigations Report 83-4063
Perennial streams are identified in a map and classified according to the relative magnitude of their 7-day, 10-year low flows. Perennial streams are identified for the entire State of Arkansas with the exception of the Mississippi Alluvial Plain. Also presented are the 7-day, 10-year low flow values at continuous-record and...
Hydraulic conductivity, specific yield, and pumpage — High Plains aquifer system, Nebraska
Robert A. Pettijohn, Hsiu-Hsiung Chen
1983, Water-Resources Investigations Report 82-4014
Hydrologic data used to evalute the ground-water potential of the High Plains aquifer system in Nebraska are presented on maps showing the hydraulic conductivity and specific yield of the aquifer system and the volume and distribution of water pumped for irrigation from the aquifer system during 1980. The High Plains...
