Our Report

The Mo is our oasis during high water in the the land of freestones.  Nymphing is the name of the game until the flows come back down.  There may be some fish looking up on the lower but this time of year, the creeks can muddy it all up.

BEST TECHNIQUES – Search for fish feeding on top. Should be tricos and caddis around. Nymphing and streamers are productive if you’re not having luck on top.

OUR TIPS OF THE WEEK – Once you hit a couple fish in a run, stay on it and continue with the same rig.

7 DAY OUTLOOK – Looks like the water is on the drop which should improve trico, caddis, and hopper fishing.

Even if we don’t get guides on the MO for the week we always are in touch with those who do and we always stock a great selection of tailwater flies.  Stop in and see us at Blackfoot River Outfitters on Reserve Street in Missoula.  We are open every day. 406-542-7411

Good luck from our team at BRO!



Fishing is ok. Wind, higher than average water, and weeds are working against you. But fish gotta eat and they are. Fish outside the box!
