History
In the 19th century, a fishing industry was centered around the Potowatomi Islands. Areas where fishing was most active were termed fishing grounds, and were termed the Sack Bay, Summer Island, St. Martin Island, and Washington Island grounds. During the peak of the industry in the 1840s and 1850s, approximately 20 fishing families lived year-round on Summer Island and several more on Rock Island. Following the introduction of the steam tug in 1869 and also as the whitefish industry declined, most fishermen left the smaller islands. Those who continued to fish moved especially to Washington Island and harbors in Big and Little Bay de Noc. Switching from the sail-powered
