CURRENT REPORT
Fall fishing is only improving on the Clark Fork. Flows are low and very managable throughout the entire river. Most float anglers are concentrated on the lower river, as the upper river is low and technical at these flows.
Our fall hatches are coming in strong on the Clark Fork. Mahogany and BWO mayflies out in force with the current conditions. Cloudy days will make for more consistent dry fly action, but trout will be looking for those bugs subsurface, too.
Fish looking for mayfly adults are falling for Brindlechutes, Purple Para. Roosters, and mahogany cripples like the DL and Better Emerger. Lots of big fish found keyed in on the BWO hatch throughout the afternoon. This is a technical game. Small BWO dries on light leader will fool these picky risers. We like the Split Flag, Film Critic, and Last Chance Cripple.
Fall mayflies not the only thing on the menu. Subsurface, fish a TJ Hooker, Pats RL, Zirdle, Jig PT, Duracell and SJ Worm. Fish will be congregated in the slower buckets first thing and move into quicker riffles in the current conditions looking for emerging mayflies.
Streamer fishing is a great option in beteween hatches. This will only improve as we get further into October. Sparkle Minnows, Kreelex, Mason's Juniors all getting chased in quick water. Big, articulated streamers starting to move fish, too. Our favorites are Mini Dungeons, Foxy Cleopatras and Rusty Trombones.
Looking Forward
It feels like fall in Missoula! Get out and enjoy the fall fishing before winter creeps in.
