2022.08.01 Level Forecast

The current level of Lake of the Woods is 324.0 m (1063.0 ft), over 95th percentile level for this time of year. The average lake level declined by 6 cm (2 in) over the past week. The lake level is above the 2014 peak of 323.78 m (1062.29 ft) and is below the record peak since regulation began of 324.31 m (1064.0 ft), set in July of 1950. The dams in Kenora remain fully open. Over the next week the lake level is expected to decline by 8 to 10 cm (3 to 4 in).

Upstream, the level of Rainy Lake is expected to re-enter its Rule Curves as of August 1st. Outflow reductions from Rainy Lake are scheduled for this week and these flow reductions will have a direct effect on the level of Lake of the Woods, increasing its rate of decline.

With decreasing inflows to Lake of the Woods, the outflow from the lake will also gradually drop. Levels along the Winnipeg River will see moderate decreases of up to 9 cm (4 in) directly below the Norman Dam and 6 cm (2 in) at Minaki.

The current level of Lac Seul is 356.71 m (1170.3 ft), 90th percentile level for this time of year. The level of the main body of Lac Seul changed little over the past week and is expected to decline by up to 3 cm (1 in) over the next week depending on rainfall. Lac Seul authorized outflow is 400 m³/s with no changes scheduled.
