Blackfoot River Outfitters's Tip of the Week

With temperatures dipping below freezing overnight and colder water in the system this week, try fishing a deeper dropper (think 3-5’ long) to get your fly further down! *See our 7 Day Outlook for updates on blockages jamming up the Bitterroot.

5-Day Outlook as of 4/20/24

7 Day Outlook: This weekend will have normal spring temperatures throughout the Bitterroot and then temperatures will start to warm up as we get into the middle of the week. The rivers have mostly stabilized after the big bump in flows last week and you can expect more consistent conditions going into this week. Dry fly fishing should be decent and improving! 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: New sweeper to be aware of below Lonepine below the split at river left! 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: Plenty of wood down, but runable with a few spots that require walking the boat to avoid jams. Be wary of this section if the river bumps. 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!

Techniques & Tips as of 4/20/24

We should see good dry fly fishing conditions on the Bitterroot again any day now, with abundant Skwalas and Blue Wings available for feeding trout. In addition to good dry fly conditions, nymphing and streamer fishing are also favorable tactics to target fish when the fish aren’t feeding on the Skwalas. As the afternoon comes around this weekend, don’t miss a good opportunity to throw a dry-dropper setup. It’s a good chance to break out your favorite foam Skwala pattern and a moderately weighted nymph, which paired together will give you ample opportunity to target rising fish as well as those hiding out lower in the water column. As temperatures heat up in the afternoon you can remove the dropper and fish a single or double dry rig. Streamers are best fished as in the mornings before it heats up and when things start to cool down in the evening. Although Skwalas get a lot of the hype, mayflies are out there as well! Bring a few of your favorite parachutes and cripple patterns. #16-20 for BWOs and #12-14 for March Browns. *Traveling or in a hurry?

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.
