Keweenaw Waterway

The Keweenaw Waterway is a partly natural, partly manmade waterway which cuts across the Keweenaw Peninsula of Michigan. Parts of the waterway are variously known as the Keweenaw Waterway, Portage Canal, Portage Lake Canal, Portage River, Lily Pond, 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.

Originally a small river used by natives for transportation and fishing, the waterway was dredged and extended in the 1860s in a joint venture between the United States Government and several mining corporations. The expanded canal allowed freighters to haul copper from the rich copper mines of the Keweenaw Peninsula out through Lake Superior to larger cities. It also enabled supply boats and freighters to reach the cities of Houghton and Hancock, which supplied goods to most of Michigan's copper region. The local mines' stamp mills dumped large quantities of stamp sand (containing traces of copper and chemical leaching agents) into the waterway, causing significant environmental damage near the sand dumps.

The area north of the waterway is known locally as Copper Island, because the waterway separates the northern part of the Keweenaw Peninsula from the mainland.

The only land route across the waterway is US 41/M-26 across the Portage Lake Lift Bridge.

The Keweenaw Waterway is part of the Keweenaw Water Trail, [ [http://www.kwta.org/ Keweenaw Water Trail Society.] ] a designated loop route (eliminating the need to spot two vehicles or obtain a shuttle) around and through the Keweenaw Peninsula for canoes and sea kayaks. It was established in 1995 and has been designated “A Superior Sports Port” by National Geographic Adventure Magazine. It is said the trail "exemplifies the Keweenaw Peninsula in the most literal sense."Fact|date=September 2008 The Lake Superior coast line is craggy and varied, claimed to be comparable to Isle Royale, but without the ferry. Uninhabited wilderness, occasional nature preserves and parks, are interspersed with sheltered harbors that offer weary paddlers the option for a warm bed, hot meal and shower at a local inn. An average paddler can cover the route in six to eight days, but extra days should be planned "to compensate for being wind-bound." The circumnavigation of the Copper Island is on its way to becoming "Michigan’s top paddling destination." Shorter trips are possible.
