The cold-water streams of the northern states provide unique recreational values to the American people (wilderness or semi-wilderness atmosphere, fast-water canoeing, and trout fishing), but the expanding recreational needs must be balanced against the growing demand of water for public and industrial supplies, for irrigation, and for the dilution of sewage and other wastes. In order to...

The Wild Rice watershed includes two general physiographic areas- the glacial Lake Agassiz Plain and a glacial moraine. The lake plain is extremely flat in the western part, sloping only a few feet per mile, but in the eastern part the plain is traversed in a north-south direction by long, narrow beach ridges up to 20 feet high. The moraine is an area of hills and depressions. The local...

The River Rouge basin is characterized by moderately hilly topography to the northwest graduating to a relatively level land surface to the south east. Stream gradients near the northwestern basin divide are relatively steep; but many become more steep in reaches where they cross beach lines of former glacial lakes. In the lower reaches of the River Rouge gradients lessen.

The Black River basin is characterized by flat topography in its central part and by more hilly areas located principally along its boundary. Stream gradients are flat, having slopes of less than 10 feet per mile, except in areas near the basin divide and in isolated areas within the basin.

Urbanization and changes in regional development in Racine and Kenosha Counties are increasing the need for water-resources information useful for planning and management. The area is fortunate in having abundant supplies of generally good quality water available for present and projected future needs. Lake Michigan and ground-water reservoirs have great potential for increased...

A procedure for the determination of quinaldine residue in various fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether, the extracts are concentrated by partitioning through 0.1N sulfuric acid, and the residues are measured by alkali flame ionization gas chromatography. Muscle tissues containing from 0.01 to 10.0 ppm quinaldine were successfully analyzed...

The purpose of this report is to make available the records of groundwater levels in the principal aquifers of the State through 1968 and to compile other related data, such as records of ground-water pumpage, data on municipal, public and industrial water-supply facilities, and the effects of precipitation on ground-water levels. Records of water levels in areas of heavy pumpage and in...

The purpose of this report is to make available the records of ground-water levels in the principal aquifers of the State through 1969 and to compile other related data, such as records of groundwater pumpage, data on municipal, public and industrial water-supply facilities, and the effects of precipitation on ground-water levels. Records of water levels in areas of heavy pumpage, and in...

The suggestion by Sanford (1967, p. 994) that the Bedford Shale, Berea Sandstone, and Sunbury Shale of the Michigan basin are of Late Devonian age because these strata contain Hymenozonotriletes lepidophytus Kedo is invalid for these formations in the Appalachian basin, the area of their type localities. Endosporites lacunosus Winslow, a synonym of Hymenozonotriletes lepidophytus Kedo...
