Aquatic Biology in Nederlo Creek, Southwestern Wisconsin

Description: From abstract: This report presents the results of biologic investigations by the U.S. Geological Survey and the Wisconsin Department of Natural Resources during a study of hydrology and water quality in a small drainage basin in the "Driftless Area" of southwest Wisconsin. The investigation included aquatic macrophytes, periphytic and planktonic algae, benthic invertebrates, and trout population dynamics during 1967-78.

Effects of a Floodwater-Retarding Structure on the Hydrology and Ecology of Trout Creek in Southwestern Wisconsin

Description: Abstract: The primary effect of a floodwater-retarding structure (FRS) on the flow of Trout Creek, Wisconsin, is attenuation of flood peaks. Reduction of flood peaks ranged from 58 to 91 percent during the study period, 1975 to 1979. An inverse relationship exists between sediment concentration and outflow from the FRS during floods. Most sediment stored in the flood pool during floods is released from the reservoir during subsequent reduced discharge. Sediment-trapping efficiency of the FRS wa… more

National Uranium Resource Evaluation, Ashland Quadrangle, Wisconsin, Michigan and Minnesota

Description: A report regarding evaluations done of the Ashland Quadrangle to find favorability for uranium occurrences in the quadrangles geologic environments. "No favorable areas could be identified or delineated on the basis of available data, and it is concluded that geologic environments in the Ashland Quadrangle are unfavorable for uranium."

[National Uranium Resource Evaluation, Ashland Quadrangle, Wisconsin, Michigan and Minnesota: Appendices]

Description: Report discussing lake-bottom sediment sampling; radon soil gas surveying, and chemical analyses for rock, stream-sediment, ground, spring-water, lake-water, and stream-water samples collected for a report discussing the favorability for uranium occurrences in geologic environments of the Ashland quadrangle of Wisconsin, Michigan, and Minnesota.

National Uranium Resource Evaluation: Eau Claire Quadrangle, Wisconsin and Minnesota

Description: Purpose and scope: The Eau Claire Quadrangle, Wisconsin and Minnesota, was evaluated to identify geologic units and delineate areas that exhibit characteristics favorable for the occurrence of uranium deposits. All geologic environments to a depth of 1500 m (5,000 ft) were evaluated by means of surface investigations and available subsurface data. Each environment was categorized as favorable, unfavorable, or unevaluated for uranium deposits based on recognition criteria contained in the study … more
