From Introduction: "The St. Cloud NTMS Quadrangle, Minnesota, was evaluated to identify and delineate areas and geologic units that have characteristics favorable for the occurrence of uranium deposits."

From Introduction: "The New Ulm 1º x 2º Quadrangle, Minnesota, was evaluated to identify and delineate areas and geologic units that have characteristics favorable for the occurrence of uranium deposits."

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 of significant uranium districts worldwide (Mickle and Mathews, eds., 1978). Evaluation of the Eau Claire Quadrangle was conducted by Golder Associates, Inc., under subcontract to Bendix Field Engineering Corporation (BFEC), for the National Uranium Resource Evaluation (NURE) program, managed by the Grand Junction Office of the U.S. Department of Energy (DOE). The evaluation program began February 1, 1978, and ended February 1, 1980. Time spent by Golder personnel on literature search, field work, evaluation of data, and preparation of the final report totaled approximately 3.5 man-years.

This report determines the possible effects of constructing an interstate highway on the nearby Rogers Lake in Dakota County, Minnesota by testing multiple water and bed material samples. This report also includes several tables and other figures.

Purpose and scope: The purpose of this report is to describe and make preliminary interpretations of: (1) Limnological characteristics of Williams Lake, based on physical, chemical, and biological data collected in 6 days in 6 different months in 1979; (2) chemical quality of ground water near the lake, based on samples collected during the summer of 1979; and (3) mineralogy of the lake sediment cores obtained in February 1978. The period of study extended from March, when the lake was covered by ice, through the period of open water, to December, when it was again covered by ice.

From introduction: The purpose of this report is to describe the general quality and quantity of water in the principal water-supply aquifers in Minnesota.

This report uses data collected from seventeen lakes and ponds in Eagan, Minnesota from 1972 through 1978 to determine the effects of urbanization on water quality. It contains a map, graphs, and tables.

From introduction: In this report, two programs have been developed for use in managing data derived from an aquifer thermal-energy storage (ATES) project being done by the University of Minnesota. Data are generated from temperature and pressure measuring devices that are read automatically by a datalogger. Up to 100 channels can be scanned every 10 seconds and recorded on magnetic tape or printed as paper output. Time period of up to several years of data may be represented on a single tape.

Abstract: Seven test holes drilled in the Glacial Lake Agassiz Peatlands indicate that the thickness of surficial materials along a north-south traverse parallel to Minnesota Highway 71 ranges from 163 feet near Blackduck, Minnesota to 57 feet about 3 miles south of Upper Red Lake. Lenses of sand and gravel occur immediately above bedrock on the Itasca moraine and are interbedded with lake clay and till under the peatlands. Vertical head gradients measured in a piezometer nest near Blackduck on the moraine are downward, indicative of recharge to the regional ground-water-flow system. Vertical head gradients are upward in a piezometer nest on a sand beach ridge in the peatlands 12 miles north of Upper Red Lake. Numerical sectional models indicate that this discharge probably comes from local flow systems recharge from ground-water mounds located under large raised bogs.

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."
