Blackfoot River Outfitters's Tip of the Week

Adding split shot to your indicator nymph rig is very important when wade fishing. The added weight of the split shot will get your flies in the strike zone faster, resulting in more opportunities for fish to eat on each drift. We like to use split shot even when fishing tungsten bead flies. Shot is less important when fishing from a drift boat or raft because you can achieve much longer drifts, but we still use it when fishing flies that are weightless or have small beads.

5-Day Outlook as of 12/4/25

It’s going to be an unseasonable fishable week around Missoula with highs ranging from the high-30’s to mid 40’s. Lot’s of precipitation expected in the form of both snow and rain. If cabin fever is already kicking in, this weekend and early next week will be a great time to get a little more trout fishing in.

Techniques & Tips as of 12/4/25

While you may see a few fish rising to midges, subsurface fishing is going to be the most reliable way to get into fish. Focus on the many deep, slow areas of the Clark Fork. Swinging a streamer will keep the bobber haters busy. Streamers: Kreelex, Chicago Overcoat, Wooly Bugger, Sparkle Minnow, Micro Dungeon, Sculpzilla Nymphs: San Juan Worm, Trinas Squirm, TJ Hooker, Sili Leg Stone, Prince Nymph, Duracell, Jig PT, Spanish Bullett, Zebra Midge Dries: Midges

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.
