CURRENT REPORT
Not much has changed on the Clark Fork recently. Water temps starting to cool off, as restrictions have been lifted on the whole river. Still, your best fishing on the Clark Fork now is early in the day, with warmer temperatures in the afternoon turning the bite off.
Tricos hatching consistently on the Clark Fork. Big rainbows will begin to pod-up sipping these pesky little dries early in the morning this month. The best window to catch this hatch is between 8am - 11am. Our favorite tricos are the Tucker's Twiggy, Hanging Midge, Cluster and Hi-Vis Spinner.
Focus on the deeper, quicker water as the day warms up. Best fishing on the Clark Fork will be done dry-dropper fishing. Start with a big foam hopper on top. We like Chubby Chernobyls, Sweetgrass Hoppers, Henneberry Hoppers and Water Walkers.
Subsurface, fish a TJ Hooker, Pats RL, Jig Squirdle, Jig PT, Duracell and SJ Worm. Fish will be congregated in the quicker riffles in the current conditions.
Streamer fishing is a great option in beteween hatches. Sparkle Minnows, Kreelex, Mason's Juniors all getting chased in quick water.
Looking Forward
Starting to see October Caddis consistently, which means great hatches of mahogany and BWO mayflies are right around the corner! It feels like fall in Missoula!
