Cheesman Canyon is sitting at 153 CFS, crystal-clear, and every trout in the canyon has its PhD in fly inspection. If you like technical sight-fishing and long drifts, this is your fall classroom. Tricos are still running the show in the mornings, while BWOs wake up when the clouds roll in. Midges remain steady, and the canyon’s picky browns are more than happy to test your patience.
