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...

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...

This hydrologic atlas represents a part of a comprehensive study of the water resources of southeastern Michigan. The purpose of the atlas is to present data on (1) the physical features of the Belle River and its tributaries, (2) the characteristics of streamflow, (3) the quality of ground and surface waters, and (4) an evaluation of the ground-water potential of the area. The atlas is...

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...

Three thousand eyed coho salmon (Oncorhynchus kisutch) eggs from Lake Michigan stock were sent by the Department of Natural Resources to the Fish Control Laboratory, La Crosse, Wis., on January 15, 1969, for use in evaluating candidate fish-cnotrol chemicals.

Glacial drift and Cretaceous sedimentary rocks are the major aquifers in the Yellow Medicine River watershed unit. The Yellow Medicine and Minnesota Rivers are the major sources of surface water. For physiographic regions – Upland Plain, Slope, Lowland Plain, and Minnesota River Flood Plain – influence surface drainage, and the flow of ground water through the aquifers. The watershed...

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.

PURPOSE AND SCOPE The purpose of this report is to describe the physical environment, availability, distribution, characteristics, movement, quality, water problems, and use of water within the Rock-Fox River basin in order to aid in planning future water management within the basin. This report presents general information on the basin that was derived from data obtained from Federal...
