April continues to see very high precipitation amounts and flows are quickly rising across many areas of the watershed. Cold temperatures over the past week have slowed the spring melt response. However, warmer temperatures with additional rainfall this week will see flows rising much more quickly.
The current level of Lake of the Woods is 322.56 m (1058.3 ft), a 50th percentile level for this time of year. The average lake level rose by 9 cm (4 in) over the past week and is expected to increase by 15-20 cm (6-8 in) over the next week with the rapid rise in inflow.
Lake of the Woods authorized outflow is scheduled to be increased from 500 m³/s to 575 m³/s on Wednesday April 20. The Winnipeg River level immediately below Norman Dam will rise by approximately 18 cm (7 in) as a result of this flow increase. The river level rise will be less with distance downstream of Kenora with no effect expected at Minaki.
