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.
