Mechanical Failure Results in Loss of
Endangered Colorado River Fish
LAKEWOOD, Colo.- Simultaneous failure of three mechanical systems at the Upper Colorado River Endangered Fish Recovery Programs 24 Road Hatchery near Grand Junction, Colo., on Feb. 24 resulted in the loss of 30,000 1-year-old razorback suckers, an endangered fish. More than 51,000 razorback suckers at the hatchery remain unaffected.
"This is a very serious and unfortunate loss," said Frank Pfeifer of the U.S. Fish and Wildlife Service, who supervises the hatchery.
When a pump ceased to recirculate water properly in fish tanks, a pressure-sensing device did not activate an emergency backup oxygen system, Pfeifer said. In addition, an alarm to alert hatchery staff failed. Without oxygen, the fish perished.
"We took immediate action to investigate and correct the cause of this accident," Pfeifer said. "Although we couldnt duplicate the equipment failure when we tested it, we have corrected the pump problem, replaced the pressure-sensing device and reprogrammed the alarm system."
Located about three miles north of Grand Junction, the hatchery produces fish to stock in Colorado and Utah to help establish self-sustaining populations. The hatchery uses two separate water systems to protect against losing all fish in the unlikely event that one system fails. Last weeks system failure is the first in the hatcherys history.
Since it opened in 1996, the hatchery has raised more than 200,000 razorback suckers to support efforts to recover this species, one of four endangered fish species in the Colorado River Basin.
The Upper Colorado River Endangered Fish Recovery Program is a cooperative program involving federal and state agencies, environmental groups and water and power user organizations in Colorado, Utah and Wyoming. Its purpose is to recover endangered fish while allowing for development of water resources for human uses.
