The current level of Lake of the Woods is 322.75 m (1058.89 ft) a 30^th percentile level, within the normal range for this time of year. The average lake level increased by 2 cm (1 in) over the past week and is expected to increase 1 to 3 cm (0.5 to 1.2 in) over the next week. Lake of the Woods authorized outflow is 150 m³/s. With the recent precipitation and increased inflows, Lake of the Woods outflow will increase to 200 m³/s on Wednesday November 5^th.

This outflow change will cause levels along the Winnipeg River to increase by 8 cm (3 in) below the Norman Dam, by 5.5 cm (2 in) above Kimberley Rapids and by 2 cm (1 in) at the Dalles. This outflow reduction will have no impact on levels at Minaki.
