Navigation Caution

Water levels throughout the basin are generally below normal for this time of year owing to a late melt of the snowpack and extremely limited precipitation over the past several weeks. Rainfall will be required to reach normal spring and summer levels in many areas of the Winnipeg River basin.

Lake of the Woods water level is approximately 20 cm (8 in) below the Nautical Chart datum (322.78 m / 1059.0 ft).

Local depths may be even shallower as the water levels shift due to wind.

 


The current level of Lake of the Woods is 322.57 m (1058.3 ft), a 20th percentile level for this time of year. The average lake level rose by 8 cm (3 in) over the past week and is expected to rise by 3 to 7 cm (1 to 3 in) over the next week.

Lake of the Woods authorized outflow will increase from 150 to 175 m³/s on Thursday May 24. The level of the Winnipeg River immediately below the Norman Dam is expected to rise by approximately 4 cm (2 in) in response. The level at Minaki will not be affected by this flow change.

The current level of Lac Seul is 355.27 m (1165.6 ft), a 40th percentile level for this time of year. The average lake level rose by 15 cm (6 in) over the past week and is expected to rise by 10 to 20 cm (4 to 8 in) over the next week.
