Outflow changes during the winter can cause unstable ice conditions downstream of a dam. The LWCB advises the public to take precautions when venturing on the ice and to follow the ice safety guidelines published by the OPP.
The current level of Lake of the Woods is 322.44 m (1057.9 ft), a 40th percentile level for this time of year. The average lake level dropped by 4 cm (2 in) over the past week and is expected to decline by 2 to 4 cm (1 to 2 in) over the next week.
Lake of the Woods authorized outflow will be reduced from 500 to 450 m³/s on Friday March 16. The level of the Winnipeg River immediately below the Norman Dam is expected to drop by about 12 cm (5 in) in response. The level at Minaki will not be affected by this flow change.
There is a planned outage at the Kenora Powerhouse on Tuesday and Wednesday, March 20 and 21. The flow will be reduced from 450 to 420 m³/s at 9:00am CDT on Tuesday March 20 and will be restored before 7:00pm CDT on Wednesday March 21. The level of the Winnipeg River downstream of the powerhouse and dam is expected to drop by about 7 cm (3 in) and will then rise by the same amount once the flow has been restored. Areas farther downstream will see less of a level change and Minaki won't be affected by this flow variation.
The current level of Lac Seul is 354.96 m (1164.6 ft), a 40th percentile level for this time of year. The average lake level dropped by 8 cm (3 in) over the past week and is expected to decline by 4 to 7 cm (2 to 3 in) over the next week.
Lac Seul authorized outflow will be reduced from 250 to 200 m³/s on Monday March 19.
