Six lakes in the headwaters of Ely Creek form the Lake Sally system. This system is the source of water for Ishpeming and several small communities in the central part of Michigan's Upper Peninsula. During years of average precipitation, more water is used from the system than is supplied to it, and the quantity of water in lake storage is depleted. Below-normal precipitation in 1976 and early 197

Low-flow characteristics of Wisconsin streams in basins considered for work under Public Law 566 are presented in this report. The low-flow characteristics presented are the annual minimum 1-day mean flow below which the flow will fall on the average of once in 2 years (Q7,2) and the annual minimum 7-day mean flow below which the flow will fall on the average of once in 10 years (Q7,10). The low-f

Land use in the upper St. Joseph River basin of south-central Michigan is primarily agricultural. In the 144-square-mile area, the chemical and physical characteristics of water are determined by the climate and soils, as well as by land conservation practices. Municipal waste discharges affect water quality at some locations, as do the larger lakes and ponds. Data indicate that mean discharge fro

Water resources data for the 1977 water year for Michigan consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water temperature of ground water. This report contains discharge records for 195 gaging stations; stage only records for 1 gaging station; stage and contents for 5 lakes and reservoirs; wate

A map of the water table in Walworth County in southeastern Wisconsin was prepared using water levels from nearly 600 wells. The work was done as a cooperative project between the U.S. Geological Survey, the University of Wisconsin-Extension, Geological and Natural History Survey, and the Southeastern Wisconsin Regional Planning Commission. The map (scale 1:100 ,000) shows the altitude of the wate

A map (scale 1:100,000) of the water table in Racine County in southeastern Wisconsin was prepared using water levels from more than 250 wells. The work was done as a cooperative project between the U.S. Geological Survey and the Southeastern Wisconsin Regional Planning Commission. The map shows the altitude of the water table in increments of 20 feet, with supplemental 10-foot contours. The altit

A map (scale 1:100,000) of the water table in Milwaukee County in southeastern Wisconsin was prepared using water levels from more than 135 wells. The work was done as a cooperative project between the U.S. Geological Survey and the Southeastern Wisconsin Regional Planning Commission. The map shows the altitude of the water table in increments of 20 feet. The altitude ranges from less than 540 fee

The radioactive and modified tracer techniques were used to measure the reaeration coefficients of two reaches each of Black Earth Creek and the Madison Effluent Channel near Madison, Wis. Comparison of the results showed that coefficients measured with the modified technique ranged from -8.96 to +3.61 and from +15.7 to +32.2 percent different from the coefficient measured with the radioactive tra

The Copper-Nickel study region lies in the Superior Upland physiographic province and is located approximately 60 miles north of Duluth and 100 miles southeast of International Falls, Minnesota. It straddles the Laurentian Divide, which separates Hudson Bay and Lake Superior drainage. The topography exhibits a southwesterly trending lineation that parallels the strike of southeastward-dipping bedr

The 120-acre Nevin wetland at the south edge of Madison, Wis., is a discharge area of the local ground-water system. A hydrologic unit composed of drift and the upper part of an underlying sandstone sequence provides ground-water inflow. Ground water enters as springflow and as leakage upward through the organic wetland soils. The average annual water budget for the wetland was based on the 3 year
