Meet one of Utah’s native trout.
Colorado River Cutthroat Trout are native to Utah’s portion of the Colorado River Basin, including streams throughout the Green River drainage, where they have persisted for thousands of years.
Today many Colorado Cutthroat populations persist in small, isolated headwater streams. Habitat loss and degradation, barriers to movement, and competition and hybridization with nonnative trout have all contributed to declines across their historical range.
In Utah decades of conservation work have focused on protecting remaining populations, restoring and reconnecting habitat, reducing threats from nonnative trout, and returning Colorado Cutthroat to waters where they had disappeared.
These fish are an important part of Utah’s native trout heritage and a reminder of what so much of our habitat work is ultimately for.
