October 2025

A cold front is forecast to bring strong winds and rainfall to the Winnipeg River basin from Saturday, October 4^th through to Monday, October 6^th. There is the potential for moderate to significant rainfall to accompany this cold front, but it is still uncertain what areas will be most impacted. Conditions will be assessed next week and outflow increases from Lake of the Woods and Lac Seul may be required to maintain levels within the preferred ranges set in the Regulation Strategy.

The current level of Lake of the Woods is 322.71 m (1058.75 ft) a 20^th percentile level, below the normal range for this time of year. The average lake level declined by 1 cm (0.5 in) over the past week and is expected to increase by 1 to 4 cm (0.5 to 1.5 in) over the next week. Lake of the Woods authorized outflow is 150 m³/s with no changes scheduled at this time.

The current level of Lac Seul is 356.22 m (1168.7 ft), a 30^th percentile level, within the normal range for this time of year. The lake level remained stable over the last week and is expected to increase by 2.5 to 7.5 cm (1 to 3 in) over the next week depending on precipitation amounts received. Lac Seul authorized outflow is 125 m³/s with no changes scheduled at this time.
