Lac Seul is a large crescent-shaped reservoir in the northwest of the Canadian province of Ontario in the Kenora District .
It is about 240 km long, has a maximum (regulated) depth of 47.2 m and is 357 m above sea level. The water area is 1373 km², including islands it is 1657 km². The maximum depth is 47 m.
The Lac Seul is the second largest body of water, which lies entirely in the province of Ontario. The reservoir consists of larger bays, narrow canals and islands. It is a relatively shallow lake. It forms an ideal habitat for fish species such as eyeglasses , pike , real perch and muscle lungs .
Lac Seul is located on a former arm of the prehistoric lake Agassiz .
Today's Lac Seul was created by damming the English River near Lower Ear Falls in the late 1920s. This increased the water level and the water surface of the original lake.
From Lake St. Joseph , which lies in the catchment area of the Albany River and James Bay , 2.68 km³ of water has been diverted to Lac Seul annually since 1957.
Power generation
At Ear Falls , where the English River leaves the lake, there are two hydropower plants operated by Ontario Power Generation (OPG): Ear Falls (4 turbines, 17 MW, 1930–1948) and Lac Seul (alternative name: Obishikokaang Waasiganikewigamig, 12.5 MW, 52 GWh annual output, completed in 2009, Lac Seul First Nation has a 25 percent stake).
