Blackfoot River Outfitters's Tip of the Week

Don’t be afraid of the single dry. Skwalas are popping and this means fish are looking up for a big meal. The longer your drift, and tighter you are to structure, the better your chances of getting gobbled. Cut off the dropper once the fishing heats up and tuck it in tight. *See our 7 Day Outlook for updates on blockages jamming up the Bitterroot.

Water Flow Data

5-Day Outlook as of 3/21/25

More rain in the forecast (YES!). Make sure you have a rainjacket with you even if the sun is shining when you’re headed out of town. This weekend will be fairly mild, with a big warm up coming next week. Expect a good bump in flows with the warmer weather ahead. 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 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: Multiple trees down below Victor that require 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!

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.
