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...

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...
Hydrologic and chemical evaluation of the ground-water resources of northwest Elkhart County, Indiana
Thomas E. Imbrigiotta, Angel Martin Jr.
1981, Water-Resources Investigations Report 81-53
A 3-year study in northwest Elkhart County, Indiana, was done to (1) de-fine the general flow and quality of water in the outwash aquifer system, (2) determine if a well field proposed for a site at the Elkhart Municipal Airport would draw leachate from the Himco landfill, and (3) define...
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...

1981, Open-File Report 81-212
Fourteen interconnected lakes in and around the city of Winter Haven, Polk County, Fla., form the Winter Haven Chain of Lakes. Levels of the lakes during the spring of 1976 were at a record low stage for the 31 years of record. During 1960-76, rainfall had been below average for...
Effects of effluents from a coal-fired, electric-generating powerplant on local ground water near Hayden, Colorado
S. R. Ellis, P.G. Mann
1981, Open-File Report 81-1196
Data were collected at the Hayden, Colo., powerplant for about a year during 1978-79 to monitor the effects of effluent and raw-water storage ponds on the local ground water, Sage Creek, and the Yampa River. The concentration of boron in wells downgradient from the effluent ponds indicated that the ponds...
Hydraulic characteristics of an underdrained irrigation circle, Muskegon County, wastewater disposal system, Michigan
M.G. McDonald
1981, Water Supply Paper 2081
Muskegon County, Michigan, disposes of waste water by spray irrigating farmland on its waste-disposal site. Buried drains in the highly permeable unconfined aquifer at the site control the level of the water table. Hydraulic conductivity of the aquifer and drain-leakance, the reciprocal of resistance to flow into the drains, was...
Preliminary evaluation of ground-water contamination by coal-tar derivatives, St. Louis Park area, Minnesota

Operation of a coal-tar distillation and wood preserving plant for 1918-72 in St. Louis Park, Minnesota, resulted in ground-water contamination. This report presents the results of the first year (1979) of an ongoing study. By 1932, water in the Prairie du Chien-Jordan aquifer, the region 's major source of ground...
