Fishing Report Updated June 19, 2021

This Boulder River fishing report is valid between June 18 and the end of June.

The Boulder River is rapidly dropping and clearing. It is fishing well on stonefly and attractor nymphs both from the moving raft and when wade-fishing good pools accessed via the raft. It’s too high to wade fish in a general sense. Caddis, PMD, Yellow Sally, and Golden Stonefly hatches will intensify over the next week. The best fishing on the Boulder will likely occur June 25 through about July 4. The Boulder will get too low to float this year around July 15.

While flows remain above about 1000cfs, the entire lower river is floatable. Below 1000, stick to the East Boulder Road to Boulder Forks (float-wade) or from 8-Mile Bridge down to Big Timber.

Top flies right now include the “Bomb Series” stonefly nymphs, Lex’s Golden Stone, and Princes. Chubby Chernobyls and high-floating attractor dries will kick in soon.

Our next Boulder report will come out around July 1, when wade fishing will start becoming a good option.
