This statement is an update to South Nation Conservation’s (SNC) Flood Outlook Statement: Ottawa River issued on May 23, 2017. 

Ottawa River Regulation Planning Board has stated: “Ongoing rainfall of 10 to 30 mm over the basin will slow water level decline in some locations from Mattawa down to the Grenville /Hawkesbury area. Water levels are expected to continue to gradually decline in most locations along the main stem of the Ottawa River over the coming week”.

Specifically, the SNC jurisdiction received 10 to 30 mm of rain yesterday.  Environment and Climate Change Canada forecasts another 10 to 15 mm of rain this week.  Water levels between Gatineau and Hawkesbury are expected to recede slowly.  Severe flooding is not a concern at this time; however, nuisance flooding in low-lying areas may be observed.

Residents are advised to stay away from watercourses where flows are high and where banks might be unstable.  Parents are encouraged to explain these dangers to their children.

Staff will continue to monitor the water levels and weather forecasts as part of the Flood Forecasting and Warning Program and will provide updates in the event conditions change.

The public is encouraged to visit and to also report changes in water-related conditions, soil stress fractures (i.e. cracks in soil), abrupt changes in streambanks, or sudden leaning of trees in their local areas. All feedback and photos can be sent to, posted on our Facebook page (/SouthNationConservation), or Tweeted to us (@SouthNationCA).
