The Ouray National Fish Hatchery (NFH) was established in 1996 to provide refuge, propagation, and technical development to assist in the recovery of the four endangered Colorado River fish: razorback sucker, Colorado pikeminnow, bonytail, and humpbacked chub. Hatchery facilities are being constructed and full development will include rearing ponds, a solar conditioning reservoir, a fish culture building, a well field, and an ozone water treatment facility. Open to the public, Ouray NFH welcomes visitors to the hatchery for a closeup view of the fish production process. The dedicated staff are happy to answer any questions while you explore the hatchery grounds and ponds. Educational programs and hatchery tours are provided to school groups and visitors when scheduled in advance.
