Fishing in Canyonlands National Park

Canyonlands sits at the confluence of two of the American West's great rivers — the Colorado and the Green — carving the park into its four districts through sheer canyon walls and remote desert terrain.

The fishing here is river fishing, full stop: no mountain lakes, no stocked ponds, just the big water moving through red rock country. The Colorado and Green Rivers are the park's two fishable waters, and they define the experience entirely.

Above their confluence, both rivers run as flatwater — miles of calm, silty current accessible by canoe, sea kayak, or other shallow-draft boats.

Below the confluence, the combined flow drops into Cataract Canyon, a fourteen-mile stretch of Class III to V whitewater that is serious, isolated, and subject to extreme fluctuations in water level. That lower section is for experienced river runners only.

The fish you'll encounter are mostly non-native. A study at the Confluence found roughly 95 percent of fish to be non-native species, with carp and channel catfish the most commonly seen.

The native fish — Colorado pikeminnow, razorback sucker, flannelmouth sucker, humpback chub, bonytail chub — are present but protected, and many are found nowhere else.

The pikeminnow once ran to six feet and over 100 pounds; today the non-natives dominate the system. The water runs thick with sediment and swings hard with seasonal flows, which affects visibility and fishing conditions throughout the year.

To fish here, you need a valid Utah State Fishing License — no separate park fishing permit is required on top of that. Fishing is permitted in accordance with Utah state law.

For river access, a day-use river permit is required year-round for all boating day trips on the Green and Colorado Rivers and Cataract Canyon. Overnight river trips require separate permits.

All vessels must comply with federal and state laws preventing the spread of non-native aquatic species — expect boat inspections to be taken seriously. This is not a place you drive to and wade in from a pullout.

Getting on the water means committing to a river trip, managing logistics in genuinely remote terrain, and understanding that the fishing is secondary to the river itself. Come for the canyon; the catfish are a bonus.
