"The greenback cutthroat trout, Colorado’s state fish, was declared extinct over 50 years ago. But last week officials found the first confirmation that the trout are once again reproducing in the wild.
Colorado Parks and Wildlife discovered that the trout are naturally reproducing in Herman Gulch in Summit County, according to a news release.
The discovery serves as evidence that the department’s intensive reintroduction program has succeeded in bringing the fish back from the brink of extinction."
