SASKATCHEWAN — The Water Security Agency (WSA) is advising the public of rising water flows on the Â鶹´«Ã½AV Saskatchewan River, from the Alberta border to Lake Diefenbaker, due to anticipated rainfall this weekend.
Heavy precipitation is forecast for southern Alberta and parts of southern Saskatchewan. In response, Alberta has already begun increasing releases from its reservoirs to create space for new inflows.
As a result, flows on the Â鶹´«Ã½AV Saskatchewan River are expected to rise significantly—from 100 cubic metres per second (m³/s) to about 830 m³/s. Tributary flows are also likely to increase. Peak flows are anticipated around June 26.
Lake Diefenbaker has sufficient storage to handle the expected inflows, but WSA will slightly increase outflows from 65 m³/s to 75 m³/s to help manage water levels. Lake levels are expected to rise by more than one metre over the next 10 days.
WSA notes that forecasts are based on current data but may vary depending on rainfall volume, duration and location.
The agency urges the public to exercise caution around rivers and lakes, where water levels and flows can change rapidly and without warning.
WSA will continue to monitor the situation and provide updates as conditions evolve.
