Hikers Haul Bags Full Of Endangered Fish To Restock Colorado Waterways

By Matt Kroschel

CLEAR CREEK COUNTY, Colo. (CBS4) -  An army of volunteers is working to bring back an endangered fish to Colorado waterways after years of habitat destruction and humans making it hard for the special little fish to survive. The greenback cutthroat trout is Colorado's state fish -- and was once thought to be extinct.

LEADVILLE, CO - AUGUST 26: Now that a DNA mystery has been solved to verify the identity of Colorado's state fish, the state is trying to bring these greenback cutthroat trout back from the brink of extinction by breeding them in tanks at the Leadville Fish Hatchery, August 26, 2014. The Leadville hatchery, which dates to the 1880s located above 10,000 feet elevation, seems to be a good breeding ground with colder water similar to the conditions where the greenback cutthroat trout evolved.

Decades of extensive recovery and conservation efforts continue with efforts like what is happening in Clear Creek County this week, as volunteers help with introducing the fish into lakes and streams in their native range.

On Wednesday, volunteers hauled backpacks filled with fish in plastic bags up Herman Gulch Trail to release them in the creek.

The group released 900 fish and an additional 800 at a nearby creek earlier in the week.

CLEAR CREEK COUNTY, CO - JULY 17: Yearling Greenback Cutthroat trout, just released into Herman Gulch, look for cover in their new environment on July 17, 2017 in Clear Creek County near Silver Plume, Colorado. Colorado Parks & Wildlife Aquatic biologists and volunteers from Trout Unlimited released 960 pure bred Greenback Cutthroat Trout into Herman Gulch. Though presumed to be extinct by 1937, several wild populations of what were thought to be greenback cutthroat trout were discovered in the South Platte and Arkansas basins starting in the late 1950s. These discoveries launched an aggressive conservation campaign that replicated those populations across the landscape so that they could be down-listed from endangered to threatened under the Endangered Species Act. Momentum for preserving these native jewels continued to build, and in 1996, the greenback was designated as Colorado's state fish. Efforts to establish new populations have continued and Colorado Parks & Wildlife hopes the introduction of these fish into Herman Gulch will successfully increase their wild numbers.

The fish are raised in a Colorado Parks and Wildlife hatchery in Salida before being sent out to live in the wild. Greenback cutthroat trout produced at the U.S. Fish and Wildlife Service's Leadville National Fish Hatchery support the CPW fish hatchery.

Paul Winkle is an aquatic biologist for CPW and says these efforts will bring back the rich diversity to mountain streams.

"This project will hopefully lead to the fish repopulating their natural environments," Winkle said.

It's a bit like getting a gold fish from the pet store. The fish are brought from the hatchery in a big truck, loaded into plastic bags that are filled with oxygen and then sealed for the hike up the trail to the creek.

"I like to fish but this is more important because these are in danger," Trout Unlimited volunteer Greg Hardy said.

For volunteers it's an effort in love and conservation along with a great reason for a beautiful hike in the Colorado mountains.

"We couldn't do it without the volunteers," Winkle added.

Sometimes it just takes people coming together to pull off an operation like this.
