Water levels in the Rideau Valley are expected to reach levels previously reached on April 7.
Rainfall will continue to cause levels to rise again inundating those locations flooded recently in the spring freshet. Road ways in the communities on the Long Reach of the Rideau River between Kars and Kemptville have already been water covered or will be later today.
Belmont Avenue and the Windsor Park pathway in Ottawa South and Brantwood Park in Ottawa East will be flooded again. No other flooding in the urban area adjacent to the Rideau River is expected to be flooded.
All of the dams in the system have been adjusted to allow as much water as possible to pass through. However, the levels on many of the lakes in the upper watershed are high causing shoreline flooding, access issues, erosion and damage to structures. It is expected that it will take some time to return to normal levels once a peak is reached.
As the flood waters rise, so too does the hazard level. Flooded roads are dangerous to drive and walk on and moving water and slippery streambanks are not good places for anyone to be. Parents need to inform children about the dangers.
The rain is forecast to end on Sunday and a peak can be expected late Sunday or Monday.
Conservation Authority staff will continue to monitor conditions and will issue updates as warranted.
