Torch Lake sits in the midst of Copper Country – where copper was mined, milled, smelted and leached from the mid-1800s up to just 40 years ago. The production of 10.5 billion pounds of copper left in its wake stamp sands and slags and surficial materials melted into nearby waters. Researchers estimate that 200 million tons of copper ore tailings have been deposited into Torch Lake displacing nearly a quarter of the lake’s original volume. But remediation of this site is underway and progress is evident – another reason why the Great Lakes Legacy Act is instrumental and should be supported.
