Green Bay (Lake Michigan)

The bay is located in parts of five counties in Wisconsin (Brown, Door, Kewaunee, Marinette, Oconto), and two in Michigan (Delta, Menominee).

[3] The French Jesuit, Roman Catholic priest, and missionary, Father Claude-Jean Allouez said the first Mass in Oconto on December 3, 1669.

His fellow explorer Louis Joliet, with two canoes and five voyageurs of French-Indian ancestry (Métis) were on their way to find the Mississippi River.

[6] In 1671 and 1673, Louis André and Jacques Marquette described fluctuations in the water level of the bay and discussed what they thought caused them.

[12] In a study looking at fish stomach contents, walleye were found to eat between 5-6% and lake whitefish and yellow perch over the course of a year.

[13] Walleye and Lake whitefish in Green Bay for the most part do not compete for the same prey, especially south of Chambers Island.

[1][2] Lower green Bay Area of Concern was designated in 1987 under the Great Lakes Water Quality agreement.

[17] Beneficial Use Impairments (BUI) are a change in the chemical, physical or biological integrity of the Great Lakes system sufficient to cause significant environmental degradation.

Past Emergency Clean Up: In 1999 and 2000, EPA oversaw a dredging project done by some of the paper companies about 3 miles upstream from the mouth of the Lower Fox River.
