Rainy Lake
Rainy Lake (French: "lac à la Pluie"; Ojibwe: "gojiji-zaaga'igan") is a relatively large freshwater lake () straddling 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 sister cities of International Falls, Minnesota, and Fort Frances, Ontario, are situated on either side of the outflow of the river from the lake. Rainy Lake and Rainy River establish part of the boundary between the US state of Minnesota and the Canadian province of Ontario.
