Hydrogeology of glacial drift, Mesabi Iron Range, northeastern Minnesota Hydrogeology of glacial drift, Mesabi Iron Range, northeastern Minnesota

Stratified fluvial sediments occur within the glacial drift at many places in the Mesabi Iron Range area. These sediments, which are important aquifers, occur extensively between the three main till units. The thickest and most extensive aquifer consists of glaciofluvial sediments that lie between the surficial till and the middle till unit, the bouldery till. Thickness of the...

Relation of channel slope to reaeration of Michigan streams Relation of channel slope to reaeration of Michigan streams

Reaeration coefficients (k2), which are rate constants for the process of oxygen absorption from the atmosphere, have been computed for Michigan's streams using an equation developed by Bennett and Rathbun (1972). Mean velocity and mean depth data, which are necessary for the computation, have been extracted from discharge measurements made at gaging stations throughout the State. The...

Appraisal of ground water for irrigation in the Little Falls area, Morrison County, Minnesota Appraisal of ground water for irrigation in the Little Falls area, Morrison County, Minnesota

Anticipated irrigation on sandy soils has prompted evaluation of ground-water supply potential in the Little Falls area. Geologic conditions cause ground-water availability to vary widely in the area. The largest and most readily available groundwater source is the glacial outwash sand and gravel from which the soils were derived. Test augering shows that the saturated surficial outwash...

Glacial and postglacial geologic history of Isle Royale National Park, Michigan Glacial and postglacial geologic history of Isle Royale National Park, Michigan

Isle Royale was overridden by glacial ice during each of the four major glaciations of the Pleistocene Epoch, and each successive glaciation essentially obliterated all direct evidence of preceding glaciations on the island. In the waning phase of the last major glaciation, the Wisconsin Glaciation, the frontal ice margin retreated northward from at least the greater part of the Lake...

Water resources data for Michigan, water years 1972-73; Part 2, Water quality records Water resources data for Michigan, water years 1972-73; Part 2, Water quality records

Water resources data for the 1972 and 1973 water years for Michigan include records of data for the chemical and physical characteristics of surface and ground waters. Data on the quality of surface water (chemical, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as once-daily, weekly, monthly or less frequently, and at some sites...

Improvement of trout streams in Wisconsin by augmenting low flows with ground water Improvement of trout streams in Wisconsin by augmenting low flows with ground water

Approximately 2 cubic feet per second of ground water were introduced into the Little Plover River in 1968 when natural streamflow ranged from 3 to 4 cubic feet per second. These augmentation flows were retained undiminished through the 2-mile reach of stream monitored. Maximum stream temperatures were reduced as much as 5?F (3?C) at the augmentation site during the test period, although...
