Precipitation over the past week has added water to the snowpack resulting in the slow rise of many tributaries across the region.  

The Lake of the Woods Control Board issued an update on April 7, 2022, detailing their plan to regulate the outflows of Lake the Woods and Lac Seul, in accordance with the Regulation Strategy, to combat the possibility of heavy snowfall this week.  

The current level of Lake of the Woods is 322.44 m (1057.9 ft), a 35th percentile level for this time of year.  

After a week of stable level conditions, the lake is expected to rise by 3-6 cm (1-2 in) over the next week. If we do receive the above-normal precipitation that is indicated for April 13-14, the lake will rise at a faster rate.  

Last week, the Lake of the Woods Control Board authorized the outflow of Lake of the Woods to increase from 450 m³/s to 475 m³/s on Friday, April 8. Outflow adjustment is expected to continue today, Monday, April 11, to 500 m³/s.  

The level of the Winnipeg River immediately below Norman Dam is expected to rise by 6 cm (2 in) as a result of each of these flow increases, while the river level at Minaki will not be affected. Additional flow increases next week are likely if precipitation forecasts are accurate. 

The current level of Lac Seul is 354.70 m (1163.7 ft), a 40th percentile level for this time of year.

The average lake level rose by 1 cm (1/2 in) in the past week and is expected to rise by 5-8 cm (2-3 in) over the next week. 

Lac Seul authorized outflow was reduced from 125 m³/s to 100 m³/s on Tuesday, April 5. No flow changes are currently scheduled.
