River Conditions Forecast
Significant rainfall (30 to 60 mm) is forecast throughout the watershed beginning on Sunday. Combined with snowmelt runoff in the north, this precipitation is expected to fill most northern reservoirs and cause a sustained increase in water levels and flows on the main stem of the Ottawa River. With current forecasts, levels and flows are expected to rapidly increase from Mattawa down to the Montreal Region.

Level forecasts are for 24h. Discharge forecasts correspond to average daily discharges for specified dates.
Note that water levels are measured in metres above mean sea levels.
- Hydrological forecasting is based on meteorological forecasting and is therefore subject to the same level of uncertainty. These data are provided for information purposes only.
- The table is updated once in the afternoon and only on business days. The updates therefore do not take into account any changes that have occurred during the day or between two business days.
- The flow rate and actual levels can change rapidly without warning, particularly during the freshet period. We advise those using bodies of water to exercise caution and to follow safety rules at all times.
