LWCB Logo Lake of the Woods Control Board Notice Board


Issued:  2018.02.22

Normally issued weekly on Thursdays but may be issued more frequently or on other days depending on conditions.
 

 

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 322.53 m (1058.2 ft), a 40th percentile level for this time of year. The average lake level dropped by 2 cm (1 in) over the past week and is expected to decline by 1 to 3 cm (1 in) over the next week.

Lake of the Woods authorized outflow is 450 m³/s.

There are planned outages at the Norman Dam on Tuesday, Wednesday and Thursday of next week, February 27 to March 1.

- On Tuesday the flow will be reduced from 450 to 330 m³/s for about a 2-hour period between 9:00am and 11:00am CST. The level of the Winnipeg River downstream of the Dam is expected to drop by 15 to 20 cm (6 to 8 in) and will then rise by the same amount once the flow has been restored.

- On Wednesday the flow will be reduced from 450 to 390 m³/s beginning at 8:00 am CST and will return to 450 m³/s at about 2:00pm CST. The level of the Winnipeg River downstream of the Dam is expected to drop by 8 to 13 cm (3 to 5 in) and will then rise by the same amount once the flow has been restored.

- On Thursday the flow will be reduced from 450 to 390 m³/s beginning at 8:00 am CST and will return to 450 m³/s before 6:00pm CST. The level of the Winnipeg River downstream of the Dam is expected to drop by 8 to 13 cm (3 to 5 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 these flow variations.
