History of Fishing on the Colorado River Upstream of Lees Ferry
The Colorado River below Glen Canyon Dam is home to native fish species like flannelmouth and blue suckers. Two endangered fish species, razorback sucker and humpback chub, can also be found in the Marble and Grand Canyon stretches of the river. Native fish are highly susceptible to predation by fish eating predators like brown trout. As brown trout grow, they begin to feed heavily on other fish species. As sub-adults and adults brown trout are 17-times more likely to eat other fish than are rainbow trout. The increase in number of brown trout in Glen Canyon has raised concerns for fish managers. As the Glen Canyon brown trout population grows, they could migrate downstream and pose an immediate threat to native fish species like the endangered humpback chub. Brown trout are also able to thrive in warmer river water than rainbow trout and are better adapted to hunting other fish in the murky river water of the Colorado River when the Paria River and side canyons are flowing.
