A Special Notice on Basin Conditions has been posted to address concerns about the unusual winter conditions and recent regulation decisions.
The current level of Lake of the Woods is 322.56 m (1058.2 ft), a 20th percentile level, near the bottom of the normal range for this time of year. The average lake level declined by 2 cm (0.5 in) over the past week and is expected to decline by 1 to 2 cm (0.5 to 1 in) over the next week. Lake of the Woods authorized outflow is 350 m3/s with no changes scheduled.
The current level of Lac Seul is 355.05 m (1164.8 ft), a 10th percentile level, which is below normal for this time of year. The lake level declined by 10 cm (3.5 in) over the past week and is expected to decline by 9 to 10 cm (3 to 3.5 in) over the next week.
On Wednesday, February 7, maintenance at the Ear Falls Dam will result in a temporary outage with Lac Seul authorized outflow dropping to 240 m3/s that day. Once the maintenance is complete, Lac Seul authorized outflow will be restored to a new decreased authorized outflow of 275 m3/s on February 7. This outflow reduction will help to slow the rate of lake level decline.
