Water-resources information has been compiled from 82 studies in which data were collected from the Oneida Reservation and vicinity. Forty-seven studies addressed surface-water issues, 33 studies addressed ground-water issues, and 23 studies addressed aquatic-biology issues. Some multidisciplinary studies are included in more than one category. Most of the surface-water studies...

The distribution and transport of polychlorinated biphenyl (PCB) congeners was determined at two sites on Pine Creek and at the Hayton Millpond on the South Branch of the Manitowoc River in Wisconsin during 1993-95. PCB congener compositions were analyzed in the operationally defined dissolved phase, suspended particulate phase, and surficial bed sediments (0-2 centimeters depth) several...

An aquifer test of the Prairie du Chien-Jordan aquifer was conducted in the Shakopee Mdewakanton Sioux Community located southwest of the Twin Cities metropolitan area. A well open to the Jordan Sandstone was pumped at 600 gallons per minute for 57 hours. Drawdown was monitored in three observation wells located near the pumped well. These wells were open to: (1) the Jordan Sandstone...

Water Resources Division of the U.S. Geological Survey (USGS), in cooperation with State agencies, obtains a large amount of data pertaining to the water resources of Minnesota each water year. These data, accumulated during many years, constitute a valuable data base for developing an improved understanding of the water resources of the State. To make these data readily available to...

The statewide average precipitation of 31.23 inches for the 1998 water year was 0.42 inches less than the normal annual precipitation of 31.65 inches for water years 1961-90. Average precipitation values ranged from 69 percent of normal at both the Willow Reservoir WVI weather station in north central Wisconsin and Crivitz High Falls WPS weather station in northeast Wisconsin to 141...

The Intergovernmental Task Force on Monitoring has suggested studies on ambient (in-stream) and compliance (wastewater) data to determine if monitoring can be reduced locally or nationally. The similarity in temporal trends between retrospective ambient and compliance water-quality data collected from Pool 2 of the Mississippi River, USA, was determined for 1985–1995. Constituents...

The distribution and transport of polychlorinated biphenyl (PCB) congeners were determined at various sites on Cedar Creek and its receiving stream, the Milwaukee River. PCB congener distributions were determined in the operationally defined dissolved phase, suspended-particle phase, and surficial bed sediments (0?2 centimeters depth). At most sites, the relative abundances of PCB...

From 1995 through 1998, water-quality and aquatic-biological samples were collected, processed, and analyzed for the U.S. Geological Survey's National Water-Quality Assessment Program in the Upper Mississippi River Basin in Minnesota and Wisconsin. Sites were selected and samples collected for integrated studies designed to provide a comprehensive description of water-quality conditions...

Estimated rates of direct ground-water discharge to Lake Michigan range from 800 to 6,700 cubic feet per second. Highest rates are calculated for the northeastern shore of the lake. Using generalized values, total direct ground-water discharge to Lake Michigan was estimated to be about 2,700 cubic feet per second. Insufficient data are available to make similar estimates for the...

Fecal coliform and Escherichia coli (E. coli) concentrations were determined in the St. Croix National Scenic Riverway to assess whether pathogenic organisms pose a potential problem for recreational use. Samples were collected from May through September 1999 at 22 locations on the St. Croix and Namekagon Rivers. No concentrations exceeded water-quality criteria or standards set by the U...

It is now well documented that impoundment of natural waters, with inundation of terrestrial area, results in enhanced conversion of inorganic mercury to methylmercury, a form that is toxic and bioaccumulates to a greater extent than inorganic mercury. Concentrations of mercury, methylmercury, and other water-quality constituents are reported from water sampled from flood-control...

Fish communities in the Upper Mississippi River Basin have been affected by changing environmental and land-use factors. Fish communities in small streams in agricultural and urban basins were compared to the fish community in a relatively undisturbed forested basin. In small streams, nutrient inputs from fertilizer, habitat modification from channelization, hydrologic modification from...
