Flood Warning: Ottawa River - Update
This statement is an update to South Nation Conservation’s (SNC) Flood Warning: Ottawa River issued on May 4, 2017.
SNC continues to caution residents that water levels in the Ottawa River continue to increase significantly.
Environment and Climate Change Canada continues to forecast high precipitation from tonight until Sunday which will contribute to high water levels and localized flooding along the Ottawa River.
On May 5, 2017, the Ottawa River Regulation Planning Board stated: “Water levels along the main stem of the Ottawa River from Pembroke down to the Montreal area remain very high. With further rainfall forecast (20 to 60 mm) over most of the basin by the end of Saturday, significant increases in levels between Pembroke and the Montreal Region are expected. Given current forecasts and depending on location, flood levels are expected to peak on Sunday or Monday into Tuesday May 9th”. Therefore, water levels are expected to continue to increase this week and may cause significant flooding between Gatineau and Hawkesbury.
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 www.nation.on.ca 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 firstname.lastname@example.org, posted on our Facebook page (/SouthNationConservation), or Tweeted to us (@SouthNationCA).
