A boat crash Wednesday on the Diversion Canal left four people injured and was the second incident on the waterway this week.

A day earlier, a man had to land his small aircraft on the water.

On both occasions, the people involved were either unhurt or sustained minor or moderate injuries.

The accident Wednesday happened about 5:30 p.m. about two miles south of the La. 22 bridge, said Adam Einck, public information officer with the state Department of Wildlife and Fisheries.

A man driving an 18-foot recreational motorboat with four passengers, two of whom were juveniles, crossed into the wake of a boat passing from the opposite direction, which caused the 18-foot boat to go airborne, throwing its driver into the water, Einck said. The driver was not hurt.

With no one at the steering wheel, though, the boat veered and crashed into another unoccupied boat parked in a nearby boat slip, and then hit the pier, Einck said.

The four passengers in the boat were taken by ambulance and helicopter to a hospital with moderate and minor injuries, Eincke said.

A day earlier, the Ascension Parish Sheriff’s Office reported that about 7:30 p.m. Tuesday, the pilot of an ultralight, single-seat aircraft noticed something was wrong just before it went down in the Diversion Canal.

The pilot was uninjured. Emergency vehicles pulled the aircraft out of the water. It was unclear if the plane had been damaged, according to the Sheriff’s Office report.

The crash happened across from a residence on River Highlands Road, and someone who lives in the area called 911.
