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 recurrence int

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 reservoirs; wate

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.

The purpose of this report is to make available the 1977 records of water levels and related data for the principal aquifers of the State. These records and data provide a means for evaluating available ground-water supplies. Long- term records serve as a framework to which short-term records may be related. Also, water levels in areas of heavy pumping may be compared to levels in areas of little

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). Included are 5

The purpose of this report is to describe low-flow characteristics of streams in the Pecatonica-Sugar River basin, Wisconsin, where streamflow data have been collected, and to present equations for estimating low-flow characteristics at ungaged sites. Low-flow characteristics were estimated for 11 gaging stations, 25 low-flow partial-record stations, and 207 miscellaneous sites in the basin. Estim

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 be collec

A map (scale 1:100,000) of the water table in Kenosha County in southeastern Wisconsin was prepared using water levels from more than 200 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 alti

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 water table a

This report presents estimated annual and monthly water budgets for Lake Wingra and the adjacent wetland area for January 1972 through September 1972. Annually, inputs from precipitation, surface runoff, and groundwater inflow are approximately equal (31, 34, and 35 percent, respectively). Outputs include outflow from the lake into Murphy Creek (70 percent), evapotranspiration from the lake and we

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 and flood pr
