Qu’Appelle River set for overhaul
closed off by Friday.
Patrick Boyle, with the water security agency said the cutting off of water to the channel, which flows from Lake Diefenbaker will not have a major effect on the water levels of the lake.
Boyle explained that prior to the water being cut off Friday, flow out of Buffalo Pound was limited.
“(The) control structures were closed and adjusted for outflow,” he said.
Work on the channel is expected to take between two to three weeks. During this time crews will perform work which Boyle said will lead to many improvements down the road.
“Rock, riffle control structures will be built in to provide better quality for aquatic life,” Boyle said.
These control structures are built to allow aquatic species a safe area to breed in. They provide a safe environment by allowing aquatic species to lay their eggs in a place where the flow of water is more calm and where there is shelter.
Boyle added having more aquatic life, like fish is important in determining the health of a lake.
“Fish are indicators of water quality,” he said.
Besides trying to improve the water system for aquatic life, Boyle said the flooding which affected the lake and river in 2014 is also reason for this work to be done.
“(The) 2014 flooding events brought sediment into the channel,” Boyle explained.
While the channel is dry, work crews will have the chance to remove sediment and work to shore up the banks of the river, which will lead to less sediment in the water in the future.
