Progress being made to remove stamp sands in Keweenaw Peninsula affecting Buffalo Reef in Lake Superior
July 15, 2021
In advance of Lake Superior Day (July 18), MI Environment highlights an infographic in the most recent State of the Great Lakes report that briefly summarizes progress made on the effort to remove stamp sands from the Lake Superior shoreline.
Legacy contaminants such as copper mine tailings (stamp sands) from the Wolverine and Mohawk mines are migrating southward due to wave action on the Lake Superior shoreline and inundating Buffalo Reef, off the Keweenaw Peninsula.
Various efforts over the past few years, including removing a 25-foot-high stamp-sand ridge from the Lake Superior shoreline, dredging of a natural trough that is in Lake Superior north of the reef and dredging of Grand Traverse Harbor.
Behind the effort: Michigan Department of Natural Resources, U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, Keweenaw Bay Indian Community, the Great Lakes Indian Fish and Wildlife Commission and the Michigan Department of Environment, Great Lakes, and Energy.
