Development of a stream habitat index for the Northern Lakes and Forest Ecoregions Development of a stream habitat index for the Northern Lakes and Forest Ecoregions
Physical habitat was quantified in 105 randomly selected streams across the Northern Lakes and Forests Ecoregion during 1998 and 1999 to develop a stream habitat index for the region. Physical habitat measures (106) were classified into four groups: substrate, instream cover, riparian zone–land use, and geomorphology–hydrology. Variable reduction procedures yielded seven variables...

June 2002 floods in the Red River of the North basin in northeastern North Dakota and northwestern Minnesota June 2002 floods in the Red River of the North basin in northeastern North Dakota and northwestern Minnesota
The Red River of the North is a complex river system in the north-central plains of the United States. The river continues to affect the people and property within its basin. During June of 2002, major flooding occurred for the third time in 5 years in the Red River of the North Basin, especially on tributaries in northwestern Minnesota. The worst damage occurred in Roseau, Minn., where...

Ground-water resources of the uppermost confined aquifers, southern Wadena County and parts of Ottertail, Todd, and Cass Counties, central Minnesota, 1997–2000 Ground-water resources of the uppermost confined aquifers, southern Wadena County and parts of Ottertail, Todd, and Cass Counties, central Minnesota, 1997–2000
Water managers are concerned about the increase of ground-water withdrawals from high-capacity wells completed in the uppermost confined aquifers in southern Wadena County. The hydrogeologic units of primary interest in the study area are the surficial aquifer, the uppermost confining units, and the uppermost confined aquifers. The surficial aquifer underlies all but portions of the...

An integrated geophysical and hydraulic investigation to characterize a fractured-rock aquifer, Norwalk, Connecticut An integrated geophysical and hydraulic investigation to characterize a fractured-rock aquifer, Norwalk, Connecticut
The U.S. Geological Survey conducted an integrated geophysical and hydraulic investigation at the Norden Systems, Inc. site in Norwalk, Connecticut, where chlorinated solvents have contaminated a fractured-rock aquifer. Borehole, borehole-to-borehole, surface-geophysical, and hydraulic methods were used to characterize the site bedrock lithology and structure, fractures, and transmissive...

Bedrock and soil geochemistry from Voyageurs National Park, Minnesota Bedrock and soil geochemistry from Voyageurs National Park, Minnesota
Bedrock, forest floor, and mineral soil sampling in Voyageurs National Park (VNP), Minnesota in 2000 and 2001 is part of a multidisciplinary project that includes the U. S. Geological Survey, National Park Service, University of Wisconsin – La Crosse, Minnesota Pollution Control Agency, and the Minnesota Department of Natural Resources. The joint project is examining the distribution of...

A two-dimensional hydrodynamic model of the St. Clair-Detroit River waterway in the Great Lakes basin A two-dimensional hydrodynamic model of the St. Clair-Detroit River waterway in the Great Lakes basin
The St. Clair-Detroit River waterway connects Lake Huron with Lake Erie in the Great Lakes basin to form part of the international boundary between the United States and Canada. A two-dimensional hydrodynamic model is developed to compute flow velocities and water levels as part of a source water assessment of public water intakes. The model, which uses the generalized finite-element...

Determination of methyl mercury by aqueous phase ethylation, followed by gas chromatographic separation with cold vapor atomic fluorescence detection Determination of methyl mercury by aqueous phase ethylation, followed by gas chromatographic separation with cold vapor atomic fluorescence detection
A recent national sampling of streams in the United States revealed low methyl mercury concentrations in surface waters. The resulting median and mean concentrations, calculated from 104 samples, were 0.06 nanograms per liter (ng/L) and 0.15 ng/L, respectively. This level of methyl mercury in surface water in the United States has created a need for analytical techniques capable of...
