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 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...

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...

Sediment in Wisconsin streams causes economic and engineering problems in water management and reduces the value of water for nearly all uses. Sediment produces problems such as reduced reservoir capacity, navigation hazards, increased cost of water treatment, property damage, temporary loss of farmland, destruction of feeding and nesting grounds of fish, and destruction of wildlife...

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...

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

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)...
