DOW investigating fish kill in Colorado River in Glenwood
November 3, 2010
GLENWOOD SPRINGS – Colorado Division of Wildlife officials are investigating the cause of a significant fish kill in the Colorado River near Two Rivers Park in Glenwood Springs.
The agency was alerted to a number of dead fish floating up on the banks of the river near the confluence with the Roaring Fork River on Tuesday. DOW spokesman Randy Hampton said that at least 84 dead fish, including trout and whitefish, were scooped from the river.
“We had folks out there taking a look at the situation, doing water temperature and quality sampling to pinpoint the cause,” he said.
Although an exact determination was not expected until Wednesday, Hampton noted that the Glenwood Hot Springs Pool had filed a report with the Colorado Department of Public Health and Environment regarding a “maintenance problem” in which chlorine bleach was accidentally released into the river in the vicinity of the fish kill.
“We are looking into that as a possible cause,” Hampton said. “It was a small quantity.”
Neither the Department of Public Health and Environment nor the Hot Springs Pool could be reached for comment Tuesday night.

“It could be a number of factors,” Hampton said.
He said such fish kills are rare, but usually relate to a major warming of the water or some type of toxin.
“We will continue to look into it and have some more information [Wednesday],” he said.
