Durango, Colo. (AP) Wildlife officials blame human error for the deaths of 50,000 rainbow trout at a hatchery in Durango over the weekend.
The Durango Herald reports that a seasonal worker apparently forgot to reopen a water valve that supplies fresh water to the trout, leading to the deaths Sunday night.
Colorado Division of Wildlife spokesman Joe Lewandowski says the employee has been dismissed.
The newspaper says the valve had been closed for regular cleaning at the hatchery. The ten-inch, 15-month-old trout died of oxygen starvation.
Hatchery manager Toby Mourning says about 34,000 trout survived.
The hatchery was scheduled to release 156,620 fish this year.
