20 years ago Greenback Cutthroat trout were thought extinct. But after a small population was discovered southwest of Colorado Springs, they are now being reintroduced to their historical range in Colorado. Recently, Colorado Parks and Wildlife (CPW) and Colorado Trout Unlimited teamed up with 60 volunteers to carry 800 yearling trout up 2.5 miles of trail to the headwaters of Clear Creek. The Greenback Cutthroat is the state fish of Colorado and after extensive population recovery efforts by CPW, are on the rise in their home waters.
