Hydrogeologic data for the Pelican River sands aquifer have been compiled in this report for use by the public and by State and local officials in making water development and management decisions. This report will supplement an interpretive report on the hydrogeology of the Pelican River sands aquifer that is scheduled for publication in 1981. The data which were collected in 1965, 1972...

This study documents Streamflow, temperature, and water-quality conditions of Bridge Creek at Augusta, Wisconsin, and evaluates the potential effects of a proposed small impoundment on the creek. The effects are of concern to the Wisconsin Department of Natural Resources because the stream is a Class II trout stream. Average daily Streamflow, from records collected during the 1980 water...

Methods of preparation of carbon-14 and deuterium labeled N-nitroso-2(3,7-dimethyl-2,6-octadienyl) aminoethanols are described. The primary synthetic method involved alkylation of ethanolamine or ethylglycine with suitable chlorides and subsequent mild nitrosation. Isomeric 14C-nitrosamines were also prepared by selective -cleavage of the di-substituted ethanolamine with nitrous acid.

The Buffalo aquifer is the principal source of ground-water supplies in the Moorhead, Minnesota area. The aquifer is an elongate deposit of sand and gravel, which locally contains water under confined conditions. Although the Buffalo aquifer contains about 270 billion gallons of water in storage, only 120 billion gallons could be withdrawn. Largest well yields occur along the deep trough...

Marquette County, in the glaciated area of the Upper Peninsula of Michigan, includes 1,878 square miles. Precipitation averages 32 inches per year. Bedrock and glacial deposits contain materials that are good aquifers. Sedimentary bedrock units generally yield sufficient water for domestic supply and, in places, may yield more than 100 gallons per minute to large-diameter wells. In the...

Concentrations of major constituents were determined in the surface water, ground water, and precipitation in Filson Creek watershed to evaluate the effects of acid precipitation on surface-water quality during snowmelt. Concentrations of sulfate increased in Filson Creek and Omaday Lake during snowmelt from less than 2 to 12 milligrams per liter in 1977 and from less than 2 to 4...

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 studied to determine the effects on lake stage and discharge. A digital...

This study was made to identify the best predictive equations for a stream's reaeration-rate coefficient. Reaeration-rate information is needed in dissolvedoxygen modeling work, but an actual tracer measurement is not always possible. The propane-area gas-tracer method and predictive equations were compared for determination of stream-reaeration coefficients (K.2) for reaches of two...

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 water, was contaminated 3,500 feet from the plant. The hydraulic...
