Forecast for 2026-03-10

Water levels and flows along the main stem of the Ottawa River are close to seasonal values. The spring runoff over recent days has led to a slight increase in flows and water levels between Lake Deschenes and the Carillon dam. This increase is expected to continue over the coming days due to rainfall expected on Wednesday in the southern part of the basin. Water levels and flows should decrease thereafter with the expected return of colder weather later this week.
