PIERRE, S.D. – A portion of Lake Vermillion Recreation Area near Canistota is closed due to flooding.
This closure affects the park’s East Unit, which includes the east campground and east boat ramp as well as access points on the south and east sides of Lake Vermillion. Access to the West Unit of the recreation area will not be impacted.
Recent rainfall and snowmelt has caused the secondary spillway to run over, which is designed to remove heavy water pressure from the dam face on the lake.
Park Manager Derek Dorr says flooding due to spillway runoff doesn’t typically last very long, but with a higher than normal rate of snowmelt in the runoff area, he expects it will last several days. The East Unit will reopen when waters recede and the area is useable.
