The current level of Lake of the Woods is 323.97 m (1062.9 ft), over 95th percentile level for this time of year. The average lake level rose by 11 cm (4 in) over the past week. The lake level has risen 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.
The level of Lake of the Woods is expected to rise by approximately 5-7 cm (2-3 in) over the next 7 days, depending on the rainfall received across the region. Should weather be favourable, a peak may be reached by mid-June followed by a gradual drop. However, a return to normal summer levels will likely take many weeks, and will be delayed should there be a return to wet weather.
As the lake continues to rise, the outflow from the lake will very gradually rise. This should result in the level of the Winnipeg River between Kenora and Minaki also gradually rising, with any local precipitation adding temporarily to levels in this stretch of the river. The level rise over the next 7 days below Norman Dam and down to Minaki is expected to be 1-2 cm (1 in). Outflow from the Whitedog dam is expected to increase very gradually as it passes the water coming from the Norman dam, plus any local inflows.
The current level of Lac Seul is 356.76 m (1170.5 ft), over 95th percentile level for this time of year. Lac Seul inflow remains very high, resulting in a rise of 13 cm (5 in) over the past week. Lac Seul authorized outflow is 800 m³/s with no changes currently scheduled.
The main body of Lac Seul is expected to rise by 4-6 cm (2-3 in) over the next 7 days with the rate of rise continuing to slow if drier weather persists through the forecast period.
Flows and levels on the English River downstream of Lac Seul are expected to remain steady or begin declining as local tributaries have been declining over the last several days. The level of the English River at Grassy Narrows appears to have peaked and is beginning to decline. This trend is expected to continue over the coming week if the drier weather persists through the forecast period.
The level of the Winnipeg River at Boundary Falls near the Manitoba border appears to have peaked and is beginning to decline. This trend is expected to continue over the coming week if the drier weather persists through the forecast period.
