Green Bay Basin

Green Bay 
The Green Bay basin is located in northeastern Wisconsin. It consists of all of Florence, Marinette, and Oconto counties, and a big portion of Forest county, and smaller portions of Brown, Langlade, Menominee, Outagamie, Shawano, and Vilas counties. The major river systems in this basin include the Menominee, Oconto, Peshtigo, Pensaukee, Suamico, and Little Suamico Rivers. The Green Bay Basin consists of 18 watersheds. Due to atmospheric deposition of mercury, many of the waterways in this basin are impaired. Mining on the Michigan and Wisconsin border along the Menominee River has brought about much controversy because of  the environmental impacts it will have on the region. The mine’s will also impact the Native-American tribes sacred lands in the area as well. The Oconto River is well-known for its whitewater rafting and kayaking that attracts many visitors in the summer months.
