River Conditions Forecast
Flows and water levels along the main stem of the Ottawa River are slightly above normal for this time of year from Mattawa down to Pembroke due to recent precipitation. Flows and levels are expected to slightly increase in some locations today and tomorrow as more spring runoff is released from some reservoirs to provide additional storage in advance of rainfall anticipated for Saturday to Tuesday. Later on, levels and flows should stabilize, and may start to decline depending on the amount of rain received over the coming week. Please refer to the forecast section of our website for more information about the river conditions in your area. Minor flooding in low-lying areas may occur over the next few days. Low-lying areas are those locations that regularly flood during the spring freshet period.
