Summary

The best spots include the tailwater below Yellowtail Dam, known for cold, clear flows and consistent hatches. Shore access is ample along the riverbanks, though drift boat fishing offers broader reach to deep pools and eddies. Key access points are the Afterbay access site and Three Mile Fishing Access Site. Fly fishing dominates—use nymphs and dry flies like Blue-Winged Olives and PMDs, especially spring through fall. Winter midge hatches also draw action. This stretch of the Bighorn ranks among the top trout rivers in the U.S.

Angling Safety Guidelines

Know the Regulations
Check local fishing rules, seasons, size limits, and license requirements to ensure legal and sustainable angling.
Handle Fish Responsibly
Use wet hands, minimize air exposure, and release fish gently to improve survival rates when practicing catch-and-release.
Choose the Right Gear
Match your rod, line, and tackle to the species and conditions to increase success and reduce unnecessary harm to fish.
Respect the Waterway
Avoid disturbing habitat, prevent bank erosion, and keep a safe distance from spawning areas to protect ecosystems.
Keep It Clean
Pack out all line, hooks, bait containers, and trash—discarded gear can injure wildlife and degrade waterways.
