Limnological and Geochemical Survey of Williams Lake Hubbard County, Minnesota (open access)

Limnological and Geochemical Survey of Williams Lake Hubbard County, Minnesota

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.

Buried Aquifers in the Brooten-Belgrade and Lake Emily Areas, West-Central Minnesota -- Factors Related to Developing Water for Irrigation (open access)

Buried Aquifers in the Brooten-Belgrade and Lake Emily Areas, West-Central Minnesota -- Factors Related to Developing Water for Irrigation

Purpose and scope: The purpose of this report is to determine, as far as possible, the occurrence of buried aquifers and to describe their hydrologic characteristics and water-yielding capability. The evaluation is based mainly on 44 test holes drilled specifically for this investigation. These test holes are too widely spaced to correlate individual aquifers. Such correlation must await more detailed closely spaced test drilling. Forty-two test holes were drilled in the Brooten-Belgrade area; hence the mapping is restricted to this part. Two test holes were drilled in the Lake Emily area, allowing only one geologic section to be presented. PIan-view mapping would require considerable additional test drilling.

Fortran Computer Programs to Plot and Process Aquifer Pressure and Temperature Data

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.

Hydrogeologic Setting of the Glacial Lake Agassiz Peatlands, Northern Minnesota (open access)

Hydrogeologic Setting of the Glacial Lake Agassiz Peatlands, Northern Minnesota

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.

Plan of Study for the Northern Midwest Regional Aquifer-System Analysis

From abstract: Sedimentary rocks of Cambrian and Ordovician age form a major aquifer system in most of Wisconsin and Iowa, northern Illinois, northwestern Indiana, southeastern Minnesota, and northern Missouri. Many metropolitan areas depend on the aquifer for all or part of their water supplies. Declines in potentiometric head have been large in the most heavily pumped areas, most notably Chicago, Milwaukee-Waukesha, Minneapolis-St. Paul, and Des Moines.

Water Resources of the Red River of the North Drainage Basin in Minnesota (open access)

Water Resources of the Red River of the North Drainage Basin in Minnesota

The report consists of three principal sections; environmental setting, water resource management, and the hydrologic system. The environmental setting describes the land and people as related to water resources. The section on water resource management is intended to provide practical information needed for the planning and management of water resources. The section on the hydrologic system is a more technical discussion of water in the Red River basin. The section on water management can be used to locate the water, determine the amount available and its quality; whereas, the section on the hydrologic system describes the operation of the system how water moves through the system and why the quality is as it is.
