April Runoff Update - Winter Storm Advisory

Environment and Climate Change Canada has issued a winter storm watch for southeastern Saskatchewan for Monday April 11, 2022.

Snowfall accumulations are forecast to be highest in the Souris River Basin with amounts expected between 30 and 50 centimetres.

With snowmelt runoff largely complete for this area of the province, the Water Security Agency (WSA) does not expect significant impacts to water flows and levels in the Souris River Basin, including Long and Moose Mountain creeks.

The additional snowfall predicted will bring Boundary, Rafferty, and Grant Devine closer to the preferred operating levels for these reservoirs.

The lower temperatures projected for the week are expected to help moderate any runoff from the potential snowfall from Environment Canada’s winter storm warning and are not expected to affect the Qu’Appelle system significantly.

WSA also advises that if the winter storm causes power disruptions to local municipal water systems, local drinking water advisories may be issued as required.

WSA will continue to monitor and provide updates to the potential runoff effects from this winter storm watch and the runoff across the province as the spring melt continues.
