Greenback Cutthroat Trout, Imperiled State Fish, Stocked in Lake as Part of Recovery

The Colorado state fish has a new home.

Last week, biologists released 1,200 greenback cutthroat trout into Zimmerman Lake, about an hour and a half west of Fort Collins. The four-inch-long, one-year-old fish were raised in hatcheries and are the descendants of the last known wild greenback population, which lives in Bear Creek outside Colorado Springs. The release was the latest effort in a decades-long journey to save the fish from extinction -- a journey that has included several rounds of setbacks, successes and scientific breakthroughs.
