Warm Temperatures Create Rapid Melt in Eastern Saskatchewan
April 18, 2016 – The Water Security Agency (WSA) is advising the public that a high pressure system with above seasonal temperatures combined with significant snow cover in the Assiniboine River Basin north of Yorkton could result in a rapid snow melt.
While WSA does not expect major flooding issues in the area, there could be some out of bank flows and the potential for some roadways to be overtopped. Peak flows are expected to be similar to the spring of 2013 and 2014. This would be well below peak levels observed in the spring of 2011 and summer of 2014.
Flows in the Assiniboine River Basin are above normal with many locations still on the rise from the snow melt. This is the result of wetter than normal fall conditions and above normal precipitation in March and early April.
An above normal runoff will also impact flooding issues in any of the closed basin systems that are already high from recent years of above normal precipitation.
The rapid melt of the remaining snowpack may also result in above normal flows and some localized flooding in the Swan, Red Deer and Lower Carrot River Basins.
The Water Security Agency will issue a Spring Runoff Update tomorrow with additional peak estimates, including estimates for Fishing and Good Spirit Lake.
