The agency that looks after Saskatchewan's lakes and rivers is trying to ensure places like Last Mountain Lake have enough water for the summer.

The Water Security Agency announced it will be operating various water control structures soon, which could lead to ice dangers on some bodies of water.

The reason for the action, the agency said, relates to a spring runoff that is well below normal.

The agency announced Wednesday that water control systems in the Qu'Appelle River basin will be put into operation in the days ahead.

"Temperatures are forecasted to be above normal later this week and through the weekend and are expected to result in an early snow melt runoff," the agency said in a statement Wednesday.

"WSA will be operating the Craven, Echo Lake, and Crooked Lake control structures this week to store water in an effort to bring Last Mountain, Pasqua, Echo, and Crooked Lakes near the top of their desirable summer operating ranges."

Storing water, the agency said, will lead an increase in water for some lakes — and a decrease in water levels for others.

All that movement will affect ice conditions, the agency said.

"Changing lake levels combined with thinner-than-normal ice cover due to the mild winter may result in extremely hazardous conditions on the Qu'Appelle Lakes," the agency said.

Officials noted similar dangers may arise on other lakes in the province as things warm up and said people should "take extreme caution when on ice-covered lakes" this spring.
