Lac La Ronge water levels at top of normal operating levels

The water level on Lac La Ronge has risen slightly this spring.

That’s according to data from the Water Security Agency (WSA) that shows the current water level at Lac La Ronge is 364.37 meters above sea level, which is within the normal operating range between 364.10 m and 364.40 m and higher than in 2025 when it was 364.17 m.

“The Churchill River above Otter Rapids is currently seeing near normal flows for this time of the year,” states an email from the WSA to larongeNOW.

“The current flow rate is about 430 cubic meters per second (cms), which is greater than the observed peak seen last year of approximately 309 cms. It is worth noting that in 2023, 2024 and 2025, this location saw below normal flows.”

While it does appear the water level at other lakes in the region such as Bigstone Lake and Nemeiben Lake have also risen, the WSA doesn’t take measurements at those lakes.

“We do measure flows at Montreal River at the outlet of Bigstone Lake,” the email added.

“Currently, it appears that flows have stabilized around 36 cms over the past few days, which may be an indication the lake is reaching its peak.”

As for the Lac La Ronge Dam, it is currently open and will remain so for the duration of the open-water season. Operational adjustments could be made depending on precipitation and temperatures over the spring and summer.

There is no planned work at the dam this year, other than inspections and normal operational adjustments.

“WSA is forecasting that water levels at Lac La Ronge will remain near the top of the normal operating range for much of the open-water season,” the email read.
