OROFINO — A maintenance worker and Army veteran who was found dead at Dworshak Dam on June 30 died from work-related carbon monoxide poisoning, according to the Clearwater County Sheriff’s Office.

Eric Engle, an Army Corps of Engineers employee from Orofino, was operating a gas-powered pressure washer in a small access area leading to the dam’s diversion tunnel. The sheriff’s office said in a news release Tuesday that an autopsy and toxicology report revealed Engle succumbed to exhaust fumes from the pressure washer. He was 54.
