The St. Louis River, the largest U.S. tributary to Lake Superior, has a watershed of 3,634 square miles, entering the southwestern corner of the lake between Duluth, Minnesota, and Superior, Wisconsin. The river flows 179 miles through three distinct areas: coarse soils, glacial till and outwash deposits at its headwaters; a deep, narrow gorge at Jay Cooke State Park; and red clay deposits in its lower reaches. As it approaches Duluth and Superior, it becomes a 12,000-acre freshwater estuary. The upper estuary has wilderness-like areas, while the lower estuary is characterized by urban development, an industrial harbor and a major port. The lower estuary includes St. Louis Bay, Superior Bay, Allouez Bay and the lower Nemadji River.


The St. Louis River was designated as one of 42 Areas of Concern (AOC) on the Great Lakes due to pollution problems. These problems are being addressed by the St. Louis River System Remedial Action Plan (RAP), which focuses primarily on the last 39 miles of the St. Louis River from below Cloquet, Minnesota to its mouth on Lake Superior.



2012 St. Louis River Science Summit

March 8-9, 2012

Come and learn about your natural environment!

See what research is going on in and around the St Louis River!
The goal of the conference is to provide a venue for sharing information on the St Louis River among the community, students, scientists, and natural resource managers.
This year’s theme is the St Louis River Estuary “Area of Concern to Area of Recovery”. We ask that, where possible, presenters address how their projects fit in with the Beneficial Use Impairment delisting process found here.

Everyone is welcome!

Participation is encouraged!

**Undergraduate students are encouraged to submit abstracts**

Registration deadline is Feb 10th, 2012.

Abstract submission deadline is Jan 20th, 2012.

The Summit will take place at The University of Wisconsin Superior Yellowjacket Union.
