Water levels have been dropping throughout the Rideau watershed since Saturday but not all flooded areas are fully dry yet. Water levels have dropped about 22 centimetres since the Saturday peak on the Long Reach between Burritts Rapids and Manotick. Another 34 centimetres are left to go on Hilly Lane and similar amounts on the neighbouring waterfront communities near Kemptville. Until those communities have safe access restored, the Flood Warning will remain in effect.

The decline in levels in the Long Reach will be slowed by rain forecast for tomorrow and by water that has to be released from Big Rideau Lake to alleviate high water conditions on the Rideau Canal reservoir lakes. The release of water will be synchronized as much as possible with the movement of water through the Long Reach to avoid causing levels there to increase again.

Flood waters in and near Windsor Park and in Brantwood Park in Ottawa South and East have receded as have waters in the Richmond area on the Jock River.

It continues to be important for parents to advise their children of the dangers of cold and, in places, fast moving springtime waters. Everyone needs to be cautious.

Conservation Authority staff will continue to monitor conditions and will issue updates as warranted.
