Canora Area Experiencing Rapid Melt and Localized Flooding
April 20, 2016 – The Water Security Agency (WSA) is advising the public in the Canora area that well above seasonal temperatures on Monday and Tuesday resulted in a rapid melt of snowpack and is creating a significant response in stream flows.
This region is experiencing out of bank flows and roadways are overtopping as flows in the contributing area appear to range from 1 in 10 year to a 1 in 50 year flood event. Tributary flows are expected to be at or near peak and should recede over the coming days. The public is urged to exercise caution while traveling in the Canora area during this time.
Tributaries to the Whitesand River and Good Spirit Lake, including Spirit Creek and Crooked Hill Creek, are flowing out of bank and are creating localized flooding issues.
WSA revised the forecasted peak for Good Spirit Lake, which is now expected to peak at 485.4 m in early May. This is 0.15 m lower than the 2014 peak level. Most of the inflows are expected to arrive over the coming week and could impact some low lying development around the lake as early as next week.
Last year, WSA built a permanent berm on Good Spirit Lake to protect some areas that were previously affected by flooding issues in 2010, but it is important for individual property owners to still be aware of this situation.
Flows in other areas of east central Saskatchewan where concerns related to a rapid melt were raised earlier this week are generally in the 1:5 to 1:10 year range as expected. This includes the Red Deer River, Swan River, and upper portions of the Assiniboine River Basin.
