High River and Lake levels

Northern Saskatchewan sees record-high river and lake levels

Jul 24, 2020 | 12:25 PM

With all the rain that’s fallen in northern Saskatchewan since the start of April, some lakes and rivers are seeing historical highs in river and lake levels.

The Lower Churchill River, including Reindeer River and Churchill River near Sandy Bay, have already exceeded previous records.

Other areas have peaked or are projected to peak at near-record highs.

Saskatchewan’s Water Security Agency is expecting high river and lake levels to remain for the remainder of the summer.
