CINCINNATI, OH (FOX19) - Crews are still trying to figure out what cause a barge used by B&B Riverboats to sink.
The 90-foot barge started taking on water Friday night and was completely underwater by sunrise.
It dumped almost 300 gallons of oil into the river.
B&B used the barge to hold a crane and other equipment for their riverboats.
"It could be breaches of water integrity, we had a lot of driftwood, we had taken a delivery. It could be any number of scenarios that could play out," said Alex Bernstein, owner of the B&B Riverboats.
