We're told both men were in town for a bass fishing tournament and they were both wearing life jackets. But when they went over, only one surfaced.
Emergency crews searched for the missing man until his body was recovered around 5:15 p.m. His body was found not far from the scene of the crash.
"The current out there is horrible," witness Torild Ofstad said.
Two men in an 18-foot fishing boat slammed into something underwater just on the other side of the bridge. The impact knocked their engine off and sent both men overboard. Their boat then hit the bridge.
"One of them flew pretty far," Ofstad said "And I talked to him afterwards and he was pretty shaken up and he doesn't really remember anything from the impact of the boat."
Divers started searching the water, the Coast Guard helicopter offering eyes from above. For hours they halted boat traffic in the area hoping to find the missing fisherman.
Even Ofstad took to the water in a paddle boat.
"It was pretty scary," she said. "As much as I wanted to find him, I don't know what I would have done if we did."
Train traffic temporarily stopped. It resumed in the afternoon.
"Boaters, you know, we go by each other, we always wave, it's a friendly and fun community," Ofstad said. "It's like, they might have gone by us a couple of hours earlier and waved, and now we're looking for them. Yeah, it's disturbing."
The deceased boater's identity is being withheld pending notification of his family,
The other person on board the boat at the time of the crash suffered minor injuries and was treated at the scene before being released.
The cause of the crash remains under investigation.
