Bitterroot River Fishing Report

Bitterroot River Fishing Report

Bitterroot River Fishing Report

Updated Sat, Apr 27, 2024
Noted for exceptional dry fly fishing throughout its 80 mile course, the Bitterroot wonders through cottonwood bottoms in the shadow snow capped peaks.  Major hatches of stone flies, mayflies, and caddis start early in March here and continue on right through November.  The braided nature of the Bitterroot provides for delightful combination float/wade trips affording anglers to get out of the boat periodically to ply oft overlooked side channels and backwaters.  Fly fishing the Bitterroot seldom disappoints.

Conditions At-a-glance

Our Report

Tip of the Week:

Not sure what size fly you should be tying on? Here’s our advice: when the water clarity isn’t great, opt for those larger flies in your box. If a feeding trout is presented with a mayfly nymph and a stonefly nymph, they’re more likely to see that larger stonefly nymph in muddy water. Larger streamer patterns, worms and nymphs are all worthy contenders for the days where the water clarity is lacking. 

*See our 7 Day Outlook for updates on blockages jamming up the Bitterroot. 

7 Day Outlook: 

We are looking at some mixed weather conditions in the Missoula valley this week with some wet and cloudy days with the sun peeking through at times. With mild daytime temperatures and night time temperatures mostly staying above freezing this week, we don’t expect any radical bumps in flows from snowmelt, although flows will likely go up gradually throughout the week as we get rain. 

If you are floating please use extreme caution. This river changes rapidly and is known for producing fatal log jams. Give us a call for an updated obstruction report. If you see any issues be sure to call us or send pics so we can share the same. Thanks.

*There are currently MANY obstructions on the Bitterroot.

Hannon-Wally: Last week’s new sweeper has been cleared away. Several sweepers in this section. It is getting tougher as water drops.

Wally-Anglers: flows over Sleeping Child dam are always dicey!  Don’t consider running after a scout unless you are highly skilled.  The channel around the left side is too low to consider.

Vets-Woodside: More wood down between New Bridge and Blodgett Park.  The river right channel will require careful scouting and likely boat dragging. 

Woodside-Tucker:  New tree down in right channel need to stay left here. The left channel at the split is open but be sure to choose your splits wisely, and the right channel over the diversion dam may need to be portaged. Have a look before you run it.

Tucker-Bell: Very sketchy in the channel through the woods now that the water has come up.  Consider going somewhere else until runoff subsides.

Bell-Stevi: Follow the sign that says “GO LEFT” to miss the log jam.  A new log is exposed in the “clear” channel so proceed with caution.

Stevi-Florence: Clear.  Follow the water at any splits.  As the river fluctuates it is smart to pull over and check for any potential changes.

When In Doubt, Eddy Out! As always, we want anglers to know that they are responsible for their own wellbeing when they are on the water. As an outfitter, we will try our best to bring known dangers to light, but conditions and obstructions are always changing and we can't possibly keep up with every danger that may present itself. When in doubt, eddy out and walk downstream to get a good look at what you're dealing with! 

Best Techniques:

Nymphing and streamer fishing will be the bread and butter this week, however definitely be prepared for some dry fly fishing opportunities in the afternoons this week. We have seen great hatches of Blue Wings so bring a few of your favorite parachutes and cripples in #16-18.  There are also some Gray Drakes and March Browns in the mix so tying on a Brindle Chute or Trina’s Carnage Gray Drake in #12-14 can be productive. Browns. Larger streamers like Double Gongas, Envys and Articulated Sparkle Minnows have been fishing well tight to rocky and woody structure.

Recommended fly fishing leader

From a boat - 7.5' 3x-4x. Wading step it up to 9'

Recommended fly fishing tippet

3X, 4X and 5X will cover 90% of our fishing applications. 1-2X is great for punching out large, wind resistant dries in high dirty water. Don't drop lower than 12lb for streamers (we recommend a 4-5' 12-16lb tapered leader with a sink tip fly line). Leave the 6X at home.

Best fly fishing rod

The 9' 5WT is our do it all rod. Fast action rods will be best for most of our fishing; foam dries, dry-dropper fishing and nymphing. A fast action 6WT will be useful for large foam dries, small streamers, heavy nymph rigs and punching bugs through the afternoon wind. Bring a 7WT if you plan to fish large articulated streamers.
