2022.07.04 Level Forecast

The current level of Lake of the Woods is 324.10 m (1063.3 ft), over 95th percentile level for this time of year. The average lake level fell by 1 cm (1/2 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 and no additional actions can be taken to limit lake level rise.

Upstream of Lake of the Woods, Namakan Lake has returned to normal summer levels while Rainy Lake remains high but is dropping sharply. Flows in tributaries in the Rainy River basin are low following generally drier weather in June. With outflow from Rainy Lake gradually dropping as the lake level falls, the level of Lake of the Woods is expected to fall by 3-5 cm (1-2 in) over the next 7 days.

As the lake level begins to drop, the outflow from the lake will also slowly fall. This will result in the level of the Winnipeg River between Kenora and Minaki beginning to gradually fall over the next week by 1-2 cm (1/2 in to 1 in).

The current level of Lac Seul is 356.77 m (1170.5 ft), 85th percentile level for this time of year. The level of the main body of Lac Seul is expected to fall by 3-5 cm (1-2 in) over the next 7 days. Lac Seul authorized outflow was reduced to 600 m³/s on Monday, July 4, with no other flow changes currently scheduled.
