The overflowing Big Sioux River is off-limits for recreational use until further notice.
Gov. Mike Rounds took the advice of the Minnehaha County Sheriff's Department and signed a declaration that closes the river starting today, according to Capt. Jim Hoekman.
“Because of the high water, it's not safe,” Hoekman said.
Signs will be posted at the two canoe launch zones in Sioux Falls - in Yankton Trail and Rotary parks - and throughout the county at high-traffic intersections, according to Regan Smith with the city's Office of Risk and Emergency Management.
The last time the river was closed for recreation during the spring thaw was 1997, he said.
A violation of the temporary rule is a class 2 misdemeanor, punishable by up to 30 days in jail, a fine of up to $500 or both.
