Sep 18, 2025 01:51 pm
Between the evening of September 11 and the early hours of September 12, areas in southern Manitoba—just west of Lake of the Woods—received over 100 mm (4 in) of rain within a few hours. The same storm system brought approximately 75 to 100 mm (3 to 4 in) of rainfall to Big Traverse, resulting in an immediate rise in the level of Lake of the Woods. This much-needed precipitation has helped sustain lake levels, despite ongoing drier-than-normal conditions across the basin.
The current level of Lake of the Woods is 322.72 m (1058.8 ft) a 20th percentile level, below the normal range for this time of year. The average lake level increased by 3.0 cm (1 in) over the past week and is expected to decrease by 1 to 3 cm (1 to 2 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 356.23 m (1168.7 ft), a 30th percentile level, within the normal range for this time of year.
