Dredging

Back to Buffalo Reef Homepage >

There have been previous efforts to dredge the Grand Traverse Bay Harbor and Traverse River. The U.S. Army Corps of Engineers dredged the harbor in 2003 and 2009. The Michigan Department of Natural Resources dredged the harbor channel in summer 2017, but a fierce October storm filled the harbor channel back in. The U.S. Environmental Protection Agency provided $3.1 million for new dredging work. This project should buy the Buffalo Reef task force five to seven years to formulate a long-term plan to save the reef. In September 2019, a U.S. Army Corps of Engineers contractor completed dredging of Grand Traverse Harbor and an area of beach and Lake Superior north of the harbor. In October 2019, Michigan DNR’s contractor removed a 30-foot-high cliff (175,000 cubic yards of stamp sands) from the water’s edge at Gay. This cliff, composed of tailings from the Mohawk Mill, was eroding an average of 26 feet of material per year into Lake Superior.
