Seine River Watershed
Sturgeon Falls Dam

Seine River Watershed Information H2O Power LP owns the Sturgeon Falls dam.

The Sturgeon Falls dam controls water levels in Laseine Lake (355 ha), which is also the receiving waterbody for the Calm Lake dam. Laseine Lake is a small lake immediately downstream from the Calm Lake dam. Because of the small size of its headpond and its proximity to Calm Lake (~10km), 98% of its inflows are controlled by the Calm Lake dam. It is almost always operated in tandem with the Calm Lake dam (cascading system). Essentially whatever water flows into the upstream end of the headpond is passed out of the dam. Because of this, fluctuations are typically very low under normal operating flows for the dams.
