Upper Sacramento River fishing report
Current conditions in brief
As of October 22, 2026: Flows: About 210 CFS at Delta. Working: October Caddis pupae; Evening egg-laying flights; Daytime nymphing. Best bet: Dead-drift them or let them swing up at the end of the drift. The October Caddis are getting thicker around Dunsmuir, and the colder weather is pulling more rainbows up out of Shasta Lake.

- Fish: Resident rainbows and browns throughout, plus lake-run fish moving into the lower river.

Upper Sac questions this week
Is the Upper Sac fishing well right now?
As of October 22, 2026: The October Caddis are getting thicker around Dunsmuir, and the colder weather is pulling more rainbows up out of Shasta Lake. The latest shop report (10/20) says both. Flows are still low and easy to wade, so this is a good week to fish the Upper Sac.
What flies are working on the Upper Sacramento River right now?
