Spring rainfall prompts Rideau River flood watch

Water from the Rideau River spills onto the streets of Ottawa, on Wednesday, April 16, 2014.

This week's rainfall could bring flooding along the Rideau River.

The Rideau Valley Conservation Authority says lower-lying waterfront properties along the Long Reach of the Rideau between Kars and Kemptville will likely be the first affected.

"In particular, access to Hilly Lane, Cedar Beach, Rideau Glen and other neighbourhoods on that reach of the river can be expected to be compromised as the rain enters the system," the RVCA said in a statement Tuesday.

Flooding could reach as far north as Belmont Avenue, Rideau River Drive and Windsor Park in Old Ottawa South by Friday, the Authority warns.

The RVCA says the monitoring station at Carleton University can expect to see a surge in the river "in excess of 450 cubic metres per second." The Authority says the typical flow in that area is 320 cubic metres per second.

"Finally, be safe!" The statement says. "Ensure that children stay away from cold, fast flowing rivers and streams."
