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.

Rainbow trout (Salmo gairdnerii) were anesthetized with MS-222, catheterized, and introduced into urine collecting chambers. Twenty-four hours after introduction, a 4-hour accumulation of urine was collected to serve as the control. Water flow to the chambers was then discontinued for 30 minutes during which the oxygen content of the water exiting in the chamber dropped from 4.9 to 2.8 mg/l. Follo

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, State, and

The land surface of the Pine River basin, an area of 194 square miles, is a relatively flat or gently undulating northwest to southeast trending glacial lake plain.The plain is interrupted by small streams and by a series of former glacial lake beaches. Other irregularities are the morainal hills in the headwaters and the morainal areas that form a large part of the basin divide. Altitudes range f

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 one in a s

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 watershed the re

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 comprises 107

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 from two a

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 plain is fa
