Water levels & flows

About 96% 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 14-day forecasts are estimates, and subject to change. Northern forecasts are broadcast on local radio stations at the beginning of every month.

2022 flood

Record precipitation across southern Manitoba this spring, especially in the Winnipeg River and Red River watersheds, continues to flow into Lake Winnipeg, and through the Nelson River to Hudson Bay. Winnipeg River flows reached the highest-ever recorded and are expected to remain high all summer as water flows from Lake of the Woods and Lac Seul upstream (Please see Lake of the Woods Control Board for more information).

Floodwaters flowing into Lake Winnipeg have raised the level of the lake 5 feet since last fall to rival levels experienced during the previous 2011 flood. Lake Winnipeg water levels will be high all summer – the lake is expected to remain at its current peak level through July and to gradually recede into the fall. The risk for shoreline properties from wind storms on Lake Winnipeg is high. Manitoba Hydro, through the Lake Winnipeg Regulation Project, is flowing as much water as possible out of Lake Winnipeg to the Nelson River. River flows and lake levels on the Nelson River will also be high all summer and into the fall. Manitoba Hydro is working with the numerous communities on the Nelson River waterway affected by these extreme flows and levels.
