Blackfoot River Fishing Report 11/21

We’ve been enjoying a stretch of warmer weather, and with the spawn now wrapped up, the river is settling into a more predictable late-season pattern. Flows have remained steady, and although still on the lower side for this time of year, water clarity is excellent. Temperatures have bumped upward enough to keep fish active throughout the day, and after the stress of the spawn, trout are spreading back into typical holding water and feeding more consistently.

Dry-fly opportunities have tapered off with the warmer, stable conditions, and fish are far less keyed in on the surface than they were earlier in the fall. Terrestrials are effectively finished, and the last of the big autumn hatches have faded. While the odd BWO may still appear, mid-day dry-fly windows are now small and sporadic. Instead, nymphing and streamer fishing have become the reliable producers. Running a tight nymph rig or swinging streamers through mid-depth water keeps the action steady during these softer hatch periods, and trout are responding aggressively subsurface as they rebuild energy after spawning.

Nymphing remains the most consistent approach. Indicator and tightline setups alike are working well, with stonefly patterns, small mayfly nymphs, and beadhead attractors all producing. Perdigons, PTs, and Rubber Legs continue to be staples. With the spawn over, it’s still important to be mindful of side channels and shallow gravel—avoid any remaining redds and focus your efforts in the deeper, main river holding water where post-spawn fish are settling back into their winter rhythms.

Streamer fishing has become one of the strongest tactics right now. As trout recover from the spawn and look to pack on calories, they’re responding well to both modest-sized sculpin patterns and articulated streamers. Warmer days with good light favor smaller, more natural tones like olive or tan, while low-light windows and cloudy spells bring out the bite on darker, bulkier patterns. Fishing them slowly along structure—cutbanks, deep buckets, boulder seams—has been especially productive. Post-spawn trout are aggressive but selective about presentation, so vary your retrieve until you dial in the cadence they want
