Our Report

The Mo is fishing really well right now and might be your best bet for quality dry fly action in the region.  Tricos and pmds coming off heavy in the mornings then tailing off in mid day. Hoppers not bad especially lower on the river where nymphing is tough with all the moss.

BEST TECHNIQUES – Concentrate on getting in your dry fly action done before noon. Pay attention to what the fish you are feeding are actually eating – pmd’s or tricos?  After noon drop under an indicator with two nymphs or try the hopper dropper game in the skinny water – most guide boats avoid that in order to fish the deep water.

OUR TIPS OF THE WEEK – When dry fly fishing more slack and longer leaders than you normally do. When fish eat a #18 or 20 they rarely spit it quickly and you have ample time for hook sets. Not only does more slack give you a better drift it limits break offs on the hook set.

7 DAY OUTLOOK – Air temps continue to climb and with it water temps as you get further from the dam.  Fishing is going to continue to be really good but expect more company as other regional water warm and the lower MO heats up.

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 tail water flies.  Stop in and see us at Blackfoot River Outfitters on Reserve Street in Missoula.  We are open every day. 406-542-7411
