The Buffalo River watershed includes two general physiographic areas – a glacial lake plain and an glacial moraine. The lake plain, which was formed by Glacial lake Agassiz more than 9,000 years ago, is extremely flat – sloping only a few feet per mile westward near the Red River of the North. The moraine is largely an area of gently rolling hills, but in the eastern “tail” of the...

This report is intended to serve a wide range of people including educators, scientists, planners, and those who wish to enjoy travel on the river. the data-summary charts, graphs, and tables are intended to be specific enough so that users who require precise information need not resynthesise the original numerical data.

The purpose of this investigation was to evaluate the quality and quantity of the ground-water resources in the area of St. James, Minnesota. St. James is located in the center of Watonwan County in south-central Minnesota. The area is covered by a thick layer of glacial drift which is underlain by Cretaceous, Cambrian, and Precambrian rocks. St. James presently obtains its water supply...

The Otter Tail River watershed includes three general physiographic areas- a moraine and ice-contact area, an outwash plain, and the plain of Glacial Lake Agassiz. The moraine and ice-contact area is a fairly rugged complex of hills characterized by local relief of several hundred feet in some areas, particularly in the extreme north and southeastern parts of the watershed. The outwash...

Liquid and sand formulations of antimycin A were tested in laboratory waters of various temperature, hardness, pH, and turbidity against 31 species of fresh-water fish of various sizes and life stages. Each formulation of toxicant was lethal under all water conditions to fish eggs, fry, fingerlings, and adult fish. Trouts are the most sensitive and catfishes the least sensitive. Of the...

A ground-water flow system in southwestern Minnesota illustrates water movement between geologic units and between the land surface and the subsurface. The flow patterns indicate numerous zones of ground-water recharge and discharge controlled by topography, varying thicknesses of geologic units, variation in permeabilities, and the configuration of the basement rock surface. Variations...

This report was prepared as a part of the study of the water resources of Clinton, Eaton and Ingham Counties being made for the Tri-County Planning Commission by the Water Resources Division of the U. S. Geological Survey. The report describes one phase of the investigation, that is, the projections of future time-withdrawal-drawdown relationships obtained from an electric analog model...
