BEST TECHNIQUES – Throwing dries!


1. Get your float on, but flows are dropping so it will be a little more difficult. Still very doable though.
2. Throw dries!
3. Don’t ignore the side channels.

7 DAY OUTLOOK – Salmonflies are still around. Flows will continue to drop. Summer is here!

Good luck and don’t forget to stop in our Philipsburg shop Flint Creek Outdoors and our NEW JACKALOPE JOE’S coffee bar! We’re open 7:30-5 7 days a week. Be sure to stop in to talk to Josh, grab a coffee and some Orvis gear, and flies from the the best fly selection in the region.
