The Bonytail is a rare, endemic minnow of the Colorado River system, threatened with extinction because of the large-scale habitat destruction caused by the damming of the Colorado River and its tributaries. Extensive hatchery and stocking programs have brought this fish back from the brink of extinction, but it is still an extremely rare sight. The Bonytail Chub is the rarest of the four endangered fish species of the Colorado River Basin. Today, relict populations can be found in the Colorado, Little Colorado, Yampa, Green, and San Juan Rivers.
