Lac La Belle (French: "beautiful lake"), is the name given to both a lake and a small unincorporated community in Keweenaw County in the U.S. state of Michigan. The town was originally the site of a stamping plant for the copper mines of the Keweenaw, specifically the Mendota Mine and the Delaware Mine. Copper-bearing rock was transported from the mines to the stamping plant, where it was processed and loaded onto freighters. The lake is a typical "Canadian Shield" type lake averaging approximately 30 feet (9 m) deep, and empties into Lake Superior at Bete Gris, by way of both a natural channel and a dredged canal. The canal was dredged in the 1860s with funding from several copper mining companies, for use by lake freighters, carrying copper ore.
