A decades-long effort to restore the Colorado River cutthroat trout to the upper reaches of Hermosa Creek has been completed, resulting in the largest continuous stretch of waterway for the native fish species in the state.<\/p>\n

\u201cThis is a 35-plus-year vision come true,\u201d said Jim White, an aquatic biologist with Colorado Parks and Wildlife.<\/p>\n

After Western settlement in the late 1880s, the Colorado River cutthroat trout were fished to the point of extinction. Then to make matters worse, settlers dumped other, more competitive species of trout into the cutthroat\u2019s habitat.<\/p>\n

All of the factors \u2013 habitat loss, overfishing and competition with non-native species \u2013 led to a dramatic decline in the cutthroat\u2019s historic range, which once spanned Colorado, New Mexico, Utah and Wyoming.<\/p>\n

Some estimates show cutthroats are now found in just 14% of their historic natural habitat.<\/p>\n

As a result, over the years, there\u2019s been the possibility of listing the cutthroat on the U.S. Fish & Wildlife Service\u2019s endangered species list.<\/p>\n

Wanting more local control and less restrictive federal regulation, however, three states \u2013 Colorado, Utah and Wyoming \u2013 entered an agreement to lead an aggressive reintroduction program to avoid the endangered species list.<\/p>\n

The upper reaches of Hermosa Creek were instantly recognized as an ideal place for a restoration project<\/a>, both for its outstanding water quality as well as easy access through a Forest Service road that runs behind Purgatory Resort.<\/p>\n

Over the years, barriers have been installed to isolate certain stretches of water and an organic poison known as rotenone has been used to clear out invasive species, like brown, brookie and rainbow trout.<\/p>\n

All this to clear the path for cutthroat reintroduction.<\/p>\n

Last weekend, CPW stocked an estimated 4,000 cutthroat fingerlings and an additional 475 mature cutthroats in the final stretch of the Hermosa Creek project, giving the waterway back to the native fish for the first time in 100 years.<\/p>\n

And now, the project to restore 23 miles of cutthroat habitat is finally complete.<\/p>\n

\u201cWe\u2019ve worked piecemeal to get to this point,\u201d White said. \u201cAnd this is the final project area that\u2019s been completed.\u201d<\/p>\n

There is one caveat, White said: Hybridized rainbow trout were found after the application of rotenone, and though wildlife officials believe they have since removed the fish from that stretch of the creek, it will be necessary to keep monitoring it.<\/p>\n

\u201cWe\u2019re not confident where the (hybridized rainbow) came from,\u201d he said. \u201cWe\u2019re going to monitor \u2026 for the foreseeable future.\u201d<\/p>\n

\"About
About 50 volunteers helped Colorado Parks and Wildlife and the U.S. Forest Service stock the East Fork of Hermosa Creek with native Colorado cutthroat trout in July 2017. The upper reaches of Hermosa Creek now boast the longest continuous stretch of cutthroat trout habitat.<\/span>Jerry McBride\/Durango Herald file<\/span><\/figcaption><\/figure>\n<\/p>

If the hybridized rainbows start showing in increased numbers, it may be necessary to treat the stretch of water again, White said.<\/p>\n

For the stretches of upper Hermosa Creek that have been restocked with cutthroats, populations are showing encouraging signs. White said there\u2019s about 400 to 600 fish per mile, which he called a \u201cnice, healthy population.\u201d<\/p>\n

Because the area is a popular draw for anglers, there is a strict catch-and-release policy. Local fish-guiding companies have said in the past that anglers come from all over the country to fish native cutthroats.<\/p>\n

The Hermosa Creek project was a collaboration between CPW, the U.S. Forest Service and Trout Unlimited.<\/p>\n

\u201cThe San Juan National Forest and partners have put a lot of effort into the habitat improvement of the tributary and are excited to have collaborated with CPW on the restocking efforts,\u201d said Lindsey Hansen, Renewable Resources Staff Officer for the Forest Service.<\/p>\n

Buck Skillen, with the local chapter of Trout Unlimited, said the organization has contributed countless volunteer hours over the last 15 or so years in this reintroduction effort, as well as provided funding.<\/p>\n

\u201cWe stand ready to assist our partners, CPW and USFS, in on-going habitat improvement and stabilization efforts that will contribute to the safeguard of our cold water fishery in this very special place,\u201d he said.<\/p>\n
