Blackfoot River Outfitters's Tip of the Week

The Clark Fork is primetime fall fishing. Watch for foam lines holding rising fish sipping BWOs and Mahogany Duns during overcast day. During sunny warmer days, long drifts with hoppers along grass banks or swinging streamers through deep runs will produce solid fish. ***There are reports of a new tree down between Turah and Sha-Ron about half a mile above the confluence of Clark Fork and Blackfoot. Call the shop for more details 406.542.7411*** ***There are reports of a new tree down between Clinton and Turah. Call the shop for more details 406.542.7411***

Techniques & Tips as of 9/25/26

A dry-dropper with a Hopper or October Caddis up top and a BWO/Mahogany nymph underneath to pick apart bankside seams. Once you see fish rising switch to a single dry BWO or Mahogany Dun pattern on a long leader. Streamer fishing is starting to heat up. Throw a Sparkle Minnows or Peanut Envies to try and entice some bigger fish.

Description: About Clark Fork River

This major fork of the Columbia River, named after Captain William Clark of the Corps of Discovery, is the mother of all our local rivers. In proving her maternal resolve, the Clark Fork today flows clean and vibrant despite the decades of mining abuses imposed upon her by a less than conservation-minded state. Often described locally as two distinct rivers, the Clark Fork provides decidedly different characteristics on its upper and lower reaches. In the snaking meanders upstream of Missoula, butter-bellied browns explode on baitfish darting from deadfall snags and hoppers haplessly bumping along grassy undercuts. Following her confluence of the Blackfoot and Bitterroot, the Clark Fork through and below town widens and slows. (A dam was recently removed from this location and the river should continue to get better for years to come!) This is the ultimate for anglers hunting line-ripping rainbows and cutthroats on light tippets. Here, the biggest fish sip little duns and chase swimming nymphs around over knee-deep gravel bars. No matter your passion – #20 trico spinners delicately placed in rise ring lanes, dangling a needle-thin phez tail under a big bushy hoppers, or chuck'n and duck'n streamers – the Clark Fork offers a season and section for you.
