The U.S. Geological Survey (USGS) has served as the Nation’s principal collector, repository, and interpreter of earth science data for more than a century. In this capacity, the USGS in Wisconsin works in partnership with State, county, municipal public works departments, public health agencies, water and sanitation districts, Indian agencies, and other Federal agencies.

For more than 100 years, the United States Geological Survey (USGS) has provided earth-science information on which managers, scientists, and other interested citizens base decisions regarding Michigan’s natural resources and natural hazards. The non-regulatory and scientific nature of the USGS work ensures that our products are technically sound, unbiased, and equally accessible and...

The U.S. Geological Survey (USGS) maps, describes, and seeks to understand Minnesota's mineral, water, and biological resources. The USGS is known for impartial data collection and data interpretation that enable resource planners and others to make informed decisions. Today's issues are more pressing than ever - understanding natural hazards to minimize their effects on life and...

Unconsolidated glacial sand and gravel deposits provide virtually all water used by residents of the Lac du Flambeau Indian Reservation. Well yields of 10 to 20 gallons per minutecan be obtained from these deposits throughoutthe reservation. Yields of 1,200 gallons perminute are obtained from wells for a fish-rearingfacility near the village of Lac du Flambeau. Thesaturated thickness of...

Physical and aquatic biological conditions differ among the Mississippi River and its major tributaries (the St. Croix and Minnesota Rivers) in Minnesota and Wisconsin. The quality of surface water and the ecological condition of rivers affect the ways in which we use them. The St. Croix River is used for recreation; the Mississippi River is used for recreation and is a corridor for...

Government agencies, academic institutions, and volunteer monitoring groups in the State of Wisconsin collect aquatic macroinvertebrate data to assess water quality. Sampling methods differ among agencies, reflecting the differences in the sampling objectives of each agency. Lack of infor- mation about data comparability impedes data shar- ing among agencies, which can result in...

This study describes the benthic invertebrate communities of 20 benchmark streams in agricultural areas of eastern Wisconsin. Streams with minimal adverse effects from human activity were selected from four agricultural areas with differing surficial deposits and bedrock types (relatively homogeneous units, or RHU's). Most aquatic invertebrate orders were well represented in the 20...

Water-quality data were compiled from four urban stormwater monitoring projects conducted in Wisconsin between 1989 and 1994. These projects included monitoring in both storm-sewer pipes and urban streams. A total of 147 constitu ents were analyzed for in stormwater sampled from 10 storm-sewer pipes and four urban streams. Land uses represented by the storm-sewer watersheds included...

The sand and gravel aquifer in the vicinity of the Wild Rose State Fish Hatchery is approximately 200 feet thick. The aquifer consists mostly of sand that was deposited as glacial till and outwash approximately 15,000 years ago. Hydraulic conductivity of the aquifer at the hatchery, calculated from slug tests, is approximately 18 feet per day. Ground water recharges west of the hatch ery...

The U.S. Geological Survey began full-scale implementation of the National Water-Quality Assessment (NAWQA) Program in 1991. The purposes of NAWQA are to describe the status and trends in the quality of the Nation's water resources and aquatic ecosystems, and to determine factors affecting water quality at local, regional, and national scales. The Upper Mississippi River (UMIS) NAWQA...
