NATION VALLEY — Areas near the Ottawa River effected by the May 2017 flood remain at risk, although earlier predictions of water levels reaching those of two years ago have not yet panned out in the Eastern Ontario communities at risk.

Cooler than forecasted temperatures and less precipitation have helped temper the rise of the rise of the Ottawa River, according to officials. The latest joint flood warning from the watershed authorities covering the Mississippi, Rideau and South Nation rivers — issued yesterday and good through today — advises that levels in two out of three of those jurisdictions along the Ottawa  will rise to a peak over the next six days. Only South Nation Conservation’s (SNC) area of concern was predicted to have hit its highest level  yesterday — at 42.95 meters above sea level — in  Clarence-Rockland and Alfred-Plantagenet.

The Mississippi Valley Conservation Authority projects a further 30 cm rise in the Constance Bay area, where levels were 50 cm still below the 2017 peak yesterday.

The Rideau Valley Conservation Authority expects the Ottawa River area from Britannia to Cumberland to rise another 40 cm. Levels yesterday remained 25 cm below those experienced in 2017.

Residents in flood-prone areas are encouraged to closely follow evolving conditions and to take necessary measures. Sandbags are available to residents in flood-prone areas.

Officials warn people people 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.
