Rainy Lake

Rainy Lake (French: lac à la Pluie; Ojibwe: gojijii-zaaga'igan) is a relatively large freshwater lake (345 square miles (890 km2)) that straddles the border between the United States and Canada. The Rainy River issues from the west side of the lake and is harnessed to make hydroelectricity for US and Canadian locations. The U.S. city of International Falls, Minnesota, and its Canadian sister city of Fort Frances, Ontario, are situated on either side of the outflow of the river from the lake. Shown as "Lake Tecamaniouen" on the 1757 Mitchell Map and as "Lake Tekamamigovouen" on the Thomas Jefferys' 1762 Map of Canada, the river is the boundary between the two countries.
