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.

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...

An evaluation of the streamflow data available in Michigan was made to provide guidelines for planning future water resource programs. The basic steps in the evaluation procedure were (1) definition of the long-term goals of the streamflow data program in quantitative form, (2) examination and analysis of all available data to determine which goals have already been met, and (3)...

Michigan's more than 11,000 lakes are a valuable resource. Primarily, they are used for recreation but many have potential for industrial use and for water supply. Lakes have water surfaces ·that expand and decrease in area, and levels that rise and fall. Records of lakes levels show that lake stages change, have seasonal trends, and may fluctuate several feet each year. Often; these...

Concentrations of chemical constituents of Michigan streams exhibit regional patterns that are primarily a function of geology and evapotranspiration. However, in some areas waste disposal by municipal and industrial organizations has altered the natural distribution and concentrations of dissolved material. Concentration and areal distribution of chemical constitutents were found to...

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...

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...

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...

Large quantities of water are needed in the beneficiation and pelletizing processes by which the ore mined from low-grade iron-formations is upgraded into an excellent raw material for the iron and steel industry. Extensive reserves of low-grade iron-formation available for development herald an intensification of the demands upon the area's water supplies. This study was designed to...
