COLUMBUS, Ga. (AP) — A rapid that gained a notorious reputation as part of a new whitewater course on the Chattahoochee River has been reopened after dozens of rafters were dumped into the rushing water during its first week.

The Columbus Ledger-Enquirer reports that at least 10 of 17 large rafts flipped on the Cut Bait rapid shortly after the course opened in May. More than 70 of the first rafters who traversed the rapid were dumped into the river that separates Georgia and Alabama in the Columbus area.

No injuries were reported, but the rapid was off-limits to paying customers for a couple weeks after as guides went through additional training.

The additional training has led to a much higher success rate through the rapid, said Whitewater Express owner Dan Gilbert.

“We have run about 10 trips and we are seeing about an 80 percent success rate,” Gilbert said. Guides are required to make 15 trips through the course before becoming certified and officials said seven of the 25 Whitewater Express guides have qualified to run paid customers through the course.

“We are working on it every day,” Gilbert said.
