Our Report


Nymphing, streamers, dries


1. Try swinging flies for some serious fun takes and fights.

2. Nymph the deep pools.

3. Don’t over-look the importance of Scuds and Sowbugs in this tailwater fishery.

7 DAY OUTLOOK – The ‘Mo is in good shape for the spring.

Typically we have a couple guides on the MO for the week and if not we always are in touch with those who do and we 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!
