Cochrane River (Canada)
The Cochrane River is a river in Manitoba and Saskatchewan, Canada. Located in the boreal forest of the Canadian Shield, it flows from Wellbelove Bay on the northern end of Wollaston Lake in north-eastern Saskatchewan to the north-east end of Reindeer Lake in Manitoba. The river has a drainage basin of and is part of the Churchill River drainage basin.
Ottawa-Bonnechere Graben
The depressions formed by the graben across the rugged Canadian Shield were a spillway for the Great Lakes after the last Ice Age. Later they became a thoroughfare for exploration and trade. These depressions now contain the Ottawa River and its tributary the Mattawa, which rises at Trout Lake near Lake Nipissing. The latter is the source of the French River, which drains into Lake Huron. This water route, with few portages, connected Lake Huron and the Saint Lawrence River by a much shorter route than through the lower Great Lakes. It was the mainline of the French-Canadian voyageurs engaged in the fur trade; they took canoes on the waterways along this route from Montreal to the upper Great Lakes and the "pays d'en haut"—the "upper country" in the old Northwest.
