Qu'Appelle Lakes Nearing Peak Levels

July 3, 2014 - The Water Security Agency (WSA) is advising the public about the rising lake levels in the Qu'appelle basin due to the recent heavy rainfall events in eastern Saskatchewan.

These lakes are now expected to approach the flood levels seen in 2011, which caused significant flooding problems to the communities there. WSA and Government Relations have staff on the ground and offering assistance to people in the area.

Cottage owners are advised to take the proper precautions and prepare accordingly. The peaks from this event are from local inflows and are expected to arrive over the next few days.
