Blackfoot River Outfitters's Tip of the Week

Spring conditions are variable and can impact fish location and feeding activity. If you aren't finding fish in the usual winter spots, try fishing seams, pocket water, shelves, drop offs, and riffles, as rising water levels and fluctuating water temperatures can cause fish to relocate. *See our 7 Day Outlook for updates on blockages jamming up the Bitterroot.

5-Day Outlook as of 4/11/25

The upcoming week along the Bitterroot River will start off cool and cloudy, with some light rain expected on Saturday. Conditions will gradually improve with clearing skies and warming temperatures from Sunday through Tuesday, peaking around 71°F. The latter part of the week looks sunny and mild, though nights will remain chilly, occasionally dipping below freezing. 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: Several tight spots, but clear. 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: Tree down in the right channel at the split 1/4mi above the diversion channel. You can sneak through, but not recommended for less experienced rowers. Very high consequence! Tucker-Bell: Multiple trees down below Victor that require walking the boat or portaging. Bell-Stevi: Mostly clear. Follow the water. 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!

Techniques & Tips as of 4/11/25

Dry-dropper rigs early in the day with a #10 Water Walker or Chubby up top and a March Brown nymph below (#12 PT, Duracell, Bullet, or Perdigon). As the water warms, and fish begin to rise, switch over to a single Skwala dry. If you get refusals on the Skwala try sizing down, or throwing a March Brown Parachute or Cripple. Streamer fishing will also be a good option. If you see fish sipping in the calm water and eddies try a March Brown or BWO (or a double dry rig with both).

Local Species Available Year round; some tributaries closed December 1-third week of May. Check regulations before fishing.

Description: About Bitterroot River

The panoramic mountains of the Selway-Bitterroot Wilderness towering above this river make for an unforgettable setting. The Bitterroot affords anglers over 80 miles of varied freestone trout water ranging from riffles and runs to undercuts and deadfalls. This river's largest fish often rise to dry flies even in non-hatch conditions. One of our guides claims that "If you catch a fish on the Bitterroot, you could have caught it with a dry fly!" This probably isn't far from the truth in light of our fishing dries here 90% of the time (often with an additional bead head dropper). Renowned hatches of stone and may flies are in full force by March, providing the state's best early season surface action and Bitterroot river fish tend to look up for the rest of the season. Expect to catch native westslope cutthroat, rainbows and browns on any outing.
