The region should expect out of bank flows and roadways overtopping. Flows in the area appear to range from 1 in 10 year to 1 in 50 year flood events. The WSA expects tributary flows to be at or near peak and should recede over the coming days. Tributaries to the Whitesand River and Good Spirit Lake in this area, including Spirit Creek and Crooked Hill Creek, are flowing out of bank and are creating localized flooding issues.
The WSA has revised earlier forecasts for the peak at Good Spirit Lake, which is now expected to come in at 485.4 m in early May. They expect the bulk of the inflows to arrive over the coming week and impact some low lying development around the lake, as early as next week.
The public is being urged to exercise extreme caution when traveling in this area. Individuals impacted by flooding at Good Spirit Lake in the summer of 2014 may need to begin to take mitigating actions as the peak is expected to be just 0.15 m lower than the 2014 peak level.
Flows in other areas of east central Saskatchewan 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.
