Manitoba Hydro provided the following forecast on September 9 for lake levels along the Winnipeg River in the Whiteshell. For questions related to water levels in this area, please contact Manitoba Hydro.
The Winnipeg River receives most of its water from Ontario’s Lake of the Woods and Lac Seul, these flows are regulated by the LWCB. Manitoba Hydro models the expected rise and fall for lakes on the Winnipeg River downstream of Slave Falls Generating Station based on flows set by the LWCB, unregulated tributaries, and expected precipitation.
Please note:
- Operations of Caribou Falls Generating Station in Ontario and local precipitation may cause daily fluctuations in levels.
- Manitoba Hydro’s generating stations on the Winnipeg River pass on all the water received from upstream – generally referred to as “run of river”.
- This weekly forecast will be provided during the open water season.
