BRO’s Tips of the Week:

With the cold spring we’ve been having flows are on a roller coaster ride- jumping on the warmer days but dropping quickly once the temperature falls. If you find the rivers starting to drop and you’re itching to get out, focus on the upper sections of the watershed. Usually, those will fish better because they clear out quickest. Alternatively, you can explore stillwater options. Tributaries, which open 5/21, are another option.


7 Day Outlook:

The Clark Fork is on the rise again and will be tough fishing for the next week or so.  Upper Clark should still be fishable this weekend, but it is starting to jump as well.


Our Recommendations for the Best Techniques and Patterns:

Nymphing will likely be your best bet when the water is off-color. Bigger/brighter is better when vis gets low. Fish can’t eat what they can’t see! Try Girdle Bugs, TJ Hookers, Double Bead Stones, and San Juans in #6-8. If the water clears up, Lightning Bug, Jig PT, 2-Bit Hooker, Prince Nymph, Duracell, Spanish Bullet or Perdigon in #12-14 should be more productive.  Don’t hesitate to throw a Wooly, Sparkle Minnow or other small streamer under your indicator to grab attention. 


Streamer prospecting might yield results. Sparkle Minnows, Kreelexes, Zonkers, Mini Dungeons, and Thin Mints/Buggers are all good to carry on the water. If you aren’t seeing action on one color, move through a rotation to change your luck.
