Ontario
Ministry of Natural Resources is the owner of the Lac des Mille
Lacs (LDML) dam which was rebuilt by the Ontario government in 1952.
It is currently operated by Valerie Falls Limited Partnership (Brookfield
Renewable Energy Group) under an agreement with the
Ministry of Natural Resources. Lac des Mille Lacs: The Lac des Mille Lacs dam controls water levels and outflows of Lac des Mille Lacs, a large (24,510 ha) lake located at the headwaters of the Seine River system. The watershed area for the Lac des Mille Lacs dam is small (177,455 ha) relative to the size of the lake, which makes up a large proportion of the watershed area (14% of total watershed area). This means that it takes a relatively long time to replace water in the lake, which limits the amount of water level fluctuation that can occur. Inflow into the lake is uncontrolled.
