River Conditions Forecast:
Water levels and flows in most locations along the main stem of the Ottawa River are near average values for this time of the year. Levels are expected to continue increasing over the next few days due to ongoing precipitation combined with snowmelt over the central parts of the basin. Minor flooding in low-lying areas may occur over the next few days depending on the amount of precipitation received and the amount of snowmelt. Low-lying areas are those locations that regularly flood during the spring freshet period. Reservoirs throughout the basin are being used to store runoff from the northern areas.
While we do not anticipate any significant concerns to arise this weekend, Public Works will continue to monitor and have active road patrols in place throughout the long weekend. Residents can access sand and sandbags at the following locations if needed: ottawa.ca/en/health-and-public-safety/emergency-preparedness/spring-flooding-2022#sandbags

The ORRPB forecasting for the Ottawa River, which anticipates impacts from the forecast precipitation event across the basin, will result in water levels remaining below the 1:2yr flood return levels in the West Carleton and the Britannia areas. Most areas of the City along the Ottawa River do not experience an onset of flooding in low-lying areas until the 1:5yr return level is reached. Given the current ORRPB and weather forecasts, further actions are not required at this time through West Carleton or in the Britannia areas. The taskforce will remain in a monitoring stance for these areas.
The Freshet Taskforce is monitoring a secondary system which may result in further precipitation on Saturday. Should this system develop, river levels should remain below the 1:2yr level as noted above.
