Drainage areas were determined for more than 7,000 sites in Wisconsin's 11 major river basins, including all named streams draining 5 or more square miles, and all unnamed streams draining 10 or more square miles. Also determined are drainage areas for gaging stations, sewage-treatment plants, dams, major highway crossings, and other sites where discharge measurements or water-quality...

It is often difficult to obtain discharge ratings at urban gaging stations. This report presents the results of using an automated constant-rate dyedilution technique to measure discharge at two sites in Madison, Wisconsin. The sites selected have well-defined stage-discharge ratings, developed during previous hydrologic studies. One site has a 60-inch diameter concrete storm sewer and...

This report summarizes the amounts and distribution of the pumpage of ground water for public supplies from four aquifers in Wisconsin. The data are for 1979 and reflect the pumpage from about 1,100 wells in 485 communities. The distribution and amount of pumpage is estimated to be similar for subsequent years. Of the water pumped for public supplies, 95 percent comes from two major...

Quality of water in the St. Peter aquifer is generally acceptable for most uses. Sulfate concentrations increase toward the southwestern part of the aquifer because of highly mineralized leakage from overlying Cretaceous deposits. Concentrations of sodium, magnesium, and sulfate generally increase to the west, and those of calcium, bicarbonate, and chloride generally increase toward the...

Water resources data for the 1982 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 169 gaging stations; stage only records for 4 gaging stations; stage and contents for 5 lakes and...

Coal-tar derivatives from a coal-tar distillation and wood-treating plant that operated from 1918 to 1972 at St. Louis Park, Minnesota contaminated the near-surface ground water. Solutions of phenolic compounds and a water-immiscible mixture of polynuclear aromatic compounds accumulated in wetlands near the plant site and entered the aquifer. The concentration of phenolic compounds in...

The Pelican River sand-plain area includes approximately 200 square miles of outwash deposits in parts of Decker, Otter Tail, and Clay Counties in west-central Minnesota. Saturated thickness of the outwash is as much as 140 feet and yields of properly constructed wells locally may exceed 1,200 gallons per minute. Recharge to the outwash from snowmelt and rain ranged from 3.2 to 6.1...

This report summarizes the uses of water in Wisconsin for 1979, except aesthetics, navigation, and recreational use. The greatest single use of water, an instream use, was for hydroelectric power production. About 26 trillion gallons, or 93 percent, was used for this purpose. Of the other 7 percent where water is pumped to a different location, 81 percent (6 percent of all water use) was...

An investigation of flood flows from small drainage basins in Minnesota is being made to aid in the design of bridges, culverts and other highway drainage structures. Results of the investigation provide peak-flow data on streams generally with drainage areas less than 200 square miles, placing particular emphasis on those with drainage areas lees than 10 square miles. Basin parameters...
