Erosion, sediment discharge, and channel morphology in the upper Chattahoochee River basin, Georgia, with a discussion of the contribution of suspended sediment to stream quality
Robert E. Faye, W. P. Carey, J. K. Stamer, R.L. Kleckner
1980, Professional Paper 1107
The 3,550 square miles of the Upper Chattahoochee River basin is an area of diverse physiographic and land-use characteristics. The headwater areas are mountainous with steep, relatively narrow channels. Land in the headwater areas is heavily forested, but small towns and farms are common in the valleys of large streams....
Composition and properties of the Pierre Shale and equivalent rocks, northern Great Plains region
Leonard Gene Schultz, H. A. Tourtelot, J. R. Gill, J.G. Boerngen
1980, Professional Paper 1064-B
The Pierre Shale and equivalent rocks of Late Cretaceous age consist in the east-central Dakotas of several hundred feet of offshore-marine shale and minor marl; in west-central Montana near the sediment source the equivalents of the Pierre Shale consist of several thousand feet of volcanic-rich and mostly nonmarine sediments; and...

Ground-water appraisal in northwestern Big Stone County, west-central Minnesota
W.G. Soukup
1980, Open-File Report 80-568
The development of ground water for irrigation in northwestern Big Stone County has not kept up with development in other irrigable areas of the State. This is due, in part, to the absence of extensive surficial aquifers and the difficulty in locating buried aquifers. Test augering south of Beardsley outlined a...

Ground-water appraisal of the Fishkill-Beacon area, Dutchess County, New York
Deborah S. Snavely
1980, Open-File Report 80-437
The most productive aquifers in the Fishkill-Beacon area, Dutchess County, N.Y., are the sand and gravel beds in the northeast corner of the area and along the valleys of Fishkill and Clove Creeks. The average yield of these aquifers to wells is 190 gal/min (gallons per minute). The most productive...

Hydrology of the Chicod Creek basin, North Carolina, prior to channel improvements
Clyde E. Simmons, Mary C. Aldridge
1980, Open-File Report 80-680
Extensive modification and excavation of stream channels in the 6-square mile Chicod Creek basin began in mid-1979 to reduce flooding and improve stream runoff conditions. The effects of channel improvements on this Coastal Pain basin 's hydrology will be determined from data collected prior to, during, and for several years...
Hydrology and water quality of the copper-nickel study region, northeastern Minnesota
Donald I. Siegel, Donald W. Ericson
1980, Open-File Report 80-739
Data were collected on the hydrology of the Copper-Nickel study region to identify the location and nature of groundwater resources, determine the flow characteristics and general quality of the major streams, and determine the potential effects of mining copper and nickel on the hydrologic stream. Groundwater generally occurs in local...
Hydrologic setting of Williams Lake, Hubbard County, Minnesota
Donald I. Siegel, Thomas C. Winter
1980, Open-File Report 80-403
The hydrology and geology of Williams Lake watershed was studied to evaluate the accuracy of various methods used to determine precipitation and evaporation in lake water-balance studies and to define a lake and ground-water system according to approaches suggested by theoretical modeling studies. Regression analysis between estimated and measured precipitation...
