A Bureau of Reclamation truck and equipment trailer were traveling on a canal road Monday morning when they slid down an embankment into the Yakima River.
The driver was not hurt and reportedly got out on his own. His name was not released, and it was not clear what he was doing when the truck slid off the road.
Benton County sheriff’s deputies responded to the overturned vehicle about one mile downstream of the Wanawish Dam, also known as Horn Rapids Dam, in West Richland.
Bruce Hadley, diver support with Columbia Basin Dive Rescue, said they had five volunteers helping for nearly seven hours.

Dive Rescue helped two tow truck drivers get the large truck and trailer upright before the vehicles were pulled out of the river separately.
Hadley said his team also placed booms, or white flotation devices, on the water to contain spilled diesel fuel and oil. The bureau was working Monday evening to clean it up, he said.
