The Nederlo Creek basin, in the "Driftless Area" of southwest Wisconsin, is geographically and hydrologically similar to other small basins in the area. Topography is rugged, with approximately 400 feet of relief between the boundary ridge tops and the valley floor. The water-retention structures (a dry floodwater- retention structure and a 43-acre reservoir) are to provide recreation...

The Illinois Urban Drainage Area Simulator was used to analyze the effects that (1) physical changes to storm-sewer conduits, and (2) increased runoff detention and infiltration would have on storm runoff in four urban basins in Madison, Wisconsin. The model was calibrated using monitoring data for the four basins collected over a 1-year period. A brief evaluation was made of a modified...

Lov-flov characteristics of streams in the Trempealeau-Black River "basin are presented. Included are estimates of low-flow frequency and flow duration at 9 gaging stations, and low-flow frequency characteristics at 20 low-flow partial-record stations and 119 miscellaneous sites. Ten equations are provided to estimate low-flow characteristics at ungaged sites and at sites where one "base...

The intense thunderstorm of July 5-6, 1978, caused record flooding on the South Fork Zumbro River at Rochester, Minnesota. The peak discharge on July 6 was 30,500 cubic feet per second compared with 19,600 cubic feet per second for the flood of March 1965, which was the largest previously known. The 1965 flood had a recurrence interval of about 30 years, whereas the 1978 flood had a...

The manual contains methods used by the U.S. Geological Survey to collect, preserve, and analyze waters to determine their biological and microbiological properties. It supplements ' Methods for Collection and Analysis of Aquatic Biological and Microbiological Samples ' (TWRI, Book 5, Chapter A4, 1977, edited by P. E. Greeson, T. A. Ehlke, G. A. Irwin, B. W. Lium, and K. V. Slack)...

The Silurian dolomite aquifer is used for water supply in much of a 14-county area bordering Lake Michigan in eastern Wisconsin. Because of the rapidity of ground-water movement, the aquifer is susceptible to contamination by waters percolating downward from surface sources. Maps showing the distribution of permeability, the thickness of unconsolidated materials, and the depth to the...

Dependable water supplies are vital to the mining industry in the Marquette Iron Range in Michigan. Development of processes that concentrate and pelletize low-grade iron ore has permitted mining to expand during the past two decades. Water demand has increased both for iron ore concentration processes and for the area 's general development. Five main streams drain the area. Their total...

Peat is being considered for fuel in Minnesota. This study will investigate the potential effects of large-scale surface mining of peat on the hydrology and water quality of Upper Red Lake and the Tamarac River. The major aspects of the study are the characterization of the surface-water and groundwater hydrology and water quality, including the trace-metal content of the peat. Data will...

The history of deposition in the White River Reservoir was reconstructed from a study of sediment in the reservoir. Suspended-sediment concentrations, particle size, and streamflow characteristics were measured at gaging stations upstream and downstream from the reservoir from November 1975 through September 1977- Characteristics of the sediments were determined from borings and samples...

The purpose of this report is to make available the 1978 records of water levels and related data for the principal aquifers of the State. This report is written for municipalities, industries, institutions, consultants, drillers, hydrologists, and other people interested in the ground-water resources of the State.

Water resources data for the 1978 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 187 gaging stations; stage only records for 1 gaging station; stage and contents for 5 lakes and...

A map (scale 1:100,000) was prepared of the water table in Waukesha County in southeastern Wisconsin using water levels from more than 1,700 wells. The work was done as part of 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 shows...
