Water levels & flows

Nearly all of the electricity we produce is clean, renewable power generated at 16 hydroelectric generating stations around the province of Manitoba. As part of our water management, water level and flow measurements are taken throughout waterways contributing to the hydroelectric system. These level readings are from hydrometric gauging stations managed by Manitoba Hydro and Water Survey of Canada.

The 7-day forecasts are estimates, and subject to change. Northern forecasts are broadcast on local radio stations at the beginning of every month.

2022 flood fall update

Water levels on Lake Winnipeg have gradually fallen since the mid-July peak of 717.5 feet above sea level (ASL) and currently forecast to drop below 715 feet ASL prior to winter freeze-up in late fall.

Inflows were the highest-ever recorded and due to exceptional precipitation across southern Manitoba and Northwest Ontario this spring, especially in the Winnipeg River and Red River watersheds.
