🚢 Keweenaw Waterway

The Keweenaw Waterway is a partly natural, partly artificial waterway which cuts across the Keweenaw Peninsula of Michigan; it separates Copper Island from the mainland. Various parts of the waterway are known as the Keweenaw Waterway, Portage Canal, Portage Lake Canal, Portage River, Lily Pond, Torch Lake, and Portage Lake. The waterway connects to Lake Superior at its north and south entries, with sections known as Portage Lake and Torch Lake in between. The primary tributary to Portage Lake is the Sturgeon River.
