Rain Expected to Bring Water Levels Up Again on Rideau

 

(WCS - 21/2017)

May 4, 2017 – Rain forecast for Friday and Saturday is expected to cause levels to increase again.

 

Parks Canada staff had begun preparations for the opening of the Rideau Canal navigation season prior to the heavy rain last Monday. Dams that had been closed had to be re-opened to pass water through the system to bring levels down.

 

The level on the Long Reach had begun to decline but will increase again due to rain that is forecast for Friday and Saturday. A widespread weather system is forecast to drop a two day total of 35 to 70 millimetres of rain on Eastern Ontario. Communities along the Long Reach of the Rideau between Kars and Kemptville should anticipate having their access roads flooded.

 

The Rideau Canal reservoir lakes, Bobs, Wolfe, Upper Rideau and Big Rideau, have all had levels increase due to the rain last Monday. Levels are now well above the Full Supply on all four lakes. Full Supply is the threshold above which damages can occur. Wolfe and Upper Rideau levels have just begun to decline. Attempts to bring levels down on Bobs and Big Rideau Lakes have not yet been successful. Levels on all lakes can be expected to increase through until late Sunday or Monday.

 

Driving or walking in flowing water more than 30 centimetres deep is not advised. Parents need to inform children about the dangers of going near flooded areas and fast moving water in streams and ditches.

 

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