This report summarizes data collected from the outlet of Seven Beaver Lake
to the Knife Falls Dam in Cloquet during the open-water seasons of 2004 and 2005. The
investigation was a cooperative effort between three MNDNR fisheries field stations, Fond du Lac
Resource Management and 1854 Treaty Authority and represents the most comprehensive investigation
of physical, chemical and biological conditions within the mainstem of the St. Louis River.

Contaminated
Sediment Studies: St. Louis River Area of Concern
In 1987, concerns over environmental quality conditions
prompted the designation of the lower St. Louis River as
one of 43 Great Lakes areas of concern (AOCs). This includes
the segment from Cloquet, Minnesota, to Lake Superior.
