Digital models of a glacial outwash aquifer in the Pearl-Sallie Lakes area, west-central Minnesota Digital models of a glacial outwash aquifer in the Pearl-Sallie Lakes area, west-central Minnesota
-p^e need for study of lake-ground-water interchange has been accentuated by eutrophication of lakes in the Pearl-Sallie Lakes area of west-central Minnesota. The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at the land surface in the eastern part. Ground water discharges from the...

Configuration of water table and distribution of downward leakage to the Prairie du Chien-Jordan Aquifer in the Minneapolis-Saint Paul metropolitan area, Minnesota Configuration of water table and distribution of downward leakage to the Prairie du Chien-Jordan Aquifer in the Minneapolis-Saint Paul metropolitan area, Minnesota
The configuration of the water table as plotted at a contour interval of 20 feet (6 metres) on quadrangle maps (scale 1:2,500) of the Minneapolis-Saint Paul metropolitan area. Control points used for mapping were water levels in wells, lakes and sloughs, and places where topographic contours cross perennial streams. A computer program, using a variation of Darcy's law, was developed to...

Analysis of operational plan for Lake Chippewa near Winter, Wisconsin Analysis of operational plan for Lake Chippewa near Winter, Wisconsin
Historical inflows into Lake Chippewa for 39 years of record were analyzed to determine the possibility of operating the flowage within a 2-foot (0.6-metre) range of stage while maintaining a minimum discharge of 57 cubic feet per second (1.6 cubic metres per second) and limiting the maximum discharge to 7,000 cubic feet per second (200 cubic metres per second). This proposed operating...

Some limnological aspects of 20 selected lakes in Eagan and Apple Valley, Minnesota Some limnological aspects of 20 selected lakes in Eagan and Apple Valley, Minnesota
Selected physical, chemical, and biological parameters were determined to assess the quality of 20 lakes in the cities of Eagan and Apple Valley, Minn. All the lakes are eutrophic except Holland and Fish Lakes, which are mesotrophic. Some lakes (including Fish Lake) have storm sewer inlets but are not discernibly different in quality than lakes with no such inlets.

Effects of pH on toxicity of antimycin to fish Effects of pH on toxicity of antimycin to fish
Detoxification of antimycin at pH 9.5 was caused by two factors. The piscicide was biologically unavailable at the high pH, and this unavailability was reversed by decreasing the pH of water solutions. Simultaneously antimycin detoxified with time, and the resulting loss in toxicity was irreversible. The toxicity of antimycin was related to the amount of un-ionized molecules; however...

Residue dynamics of quinaldine and TFM in rainbow trout Residue dynamics of quinaldine and TFM in rainbow trout
Study of the residue dynamics of 2-methylquinoline (quinaldine) and 3-trifluoromethyl-4-nitrophenol (TFM) in rainbow trout yielded the following findings: 1. Uptake and distribution of TFM by trout was influenced by the biotransformation of the lipidsoluble free phenol. No such effect was observed with quinaldine. 2. Disappearance of quinaldine and TFM from gallbladder bile was slower...
