Yellowstone Park Waters

Fishing Conditions

June 17, 2021

The Park has shaped up fast this year. The northwest corner is fishable on all of it's rivers. The Lamar is green and ready to go! Caddis are beginning to pop but most fish are still looking for nymphs or a small dead drifted Zonker. The Gardner river is an overlooked spot that is ready to fish. Goldens may be starting to fly up from the Yellowstone rivers. The west side of the Park is still the area for the best dry fly fishing. The Firehole will be best in the first half of the day. PMD's in a smaller 16 or 18 will take some fish. The Yellowstone in the Black Canyon is fishable but still big water so be careful fishing this water.
