BRO’s Tips of the Week:

The Bitterroot doubled in flow over the past week. Flows made the water big, muddy, and not your best option for finding consistent fish. Creek and tributary fishing opens this Saturday, so smaller options and lakes will be your best bet for the next week.

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

7 Day Outlook:

Daytime highs are WARM over the weekend. We’ll have temps in the 80s before they dip back into the 70s next week. The river will be several days behind, though, so expect it to stay high for the foreseeable future.

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.

*There are currently several obstructions on the Bitterroot.  

Darby-Wally: one big sweeper down just below Lone Pine requires a drag to the right on the Darby-Wally float. There is also a tree blocking the river near the cliffs above Wally. 

Wally-Anglers: flows over Sleeping Child dam are extremely low, producing dangerous conditions and a high chance of getting stuck. 

Veterans Bridge-Woodside: take the left channel below the bridge, as the right channel is blocked and requires a portage. 

Woodside-Tucker: the left channel at the split requires a short drag, and the right channel diversion dam is so shallow that it may need to be portaged. 

Tucker-Bell: a quarter-mile section of water before Victor may require scouting and one drag due to wood in the water. 

Bell-Stevi: One new tree is down half a mile below Bell. Another tree about one mile downstream of Bell Crossing has already sunk one drift boat and will require staying far river left and doing a long drag.

Lastly, one tree is down near the Osprey Cabin  ¾ through the Stevi-Florence float. It is across the river and will require a drag to get around.

Our Recommendations for the Best Techniques and Patterns:

If you do attempt the Bitterroot, finding side channels and softer seams with slow water will be the best option. TJ Hookers in gold and coffee, San Juans, and Rubber Legs make a good first nymph, and double up with Prince Nymph, Duracells, Zirdles, and Spanish Bullets. If you throw streamers, olive and black patterns, Mini Dungeons, Baby Gongas, or Sparkle Minnows might get a chase tight to the bank.
