Willow Beach National Fish Hatchery

This coldwater hatchery, located 11 miles downriver from Hoover Dam on the Arizona side of the Colorado River, raises rainbow trout primarily as mitigation for dams on the Colorado River. Approximately 750,000 trout are stocked annually in the Colorado River from Lake Mead south to the Mexican border. Imperiled fishes, like the razorback sucker and bonytail chub, are also being grown for recovery efforts in the Colorado River.
