CHURCHILL (Missinnippi or English), the name of a river of the province of Saskatchewan and district of Keewatin, Canada. It rises in La Loche (or Methy) lake, a small lake in 56° 30′ N. and 109° 30′ W., at an altitude of 1577 ft. above the sea, and flows E.N.E. to Hudson’s Bay, passing through a number of lake expansions. Its principal tributaries are the Beaver (350 m. long), Sandy and Reindeer rivers. Between Frog and Methy portages (480 m.) it formed part of the old voyageur route to the Peace, Athabasca, and Mackenzie. It is still navigated by canoes, but has many rapids. Its principal affluent, the Reindeer, discharges the waters of Reindeer Lake (1150 ft. above the sea, with an area of 2490 sq. m.) and Wollaston Lake (altitude, 1300 ft). The Churchill is 925 m. long. Fort Churchill, at its mouth, is the best harbour in the southern portion of Hudson’s Bay. The portage of La Loche (or Methy), 1212 m. in length, connects its head waters with the Clearwater river, a tributary of the Athabasca, draining into the Arctic Ocean.
