Troutfest is a Fly Fishing Exposition and Fundraiser held in Townsend, Tennessee in the Great Smoky Mountains. Proceeds from this event are donated to Great Smoky Mountains National Park Fisheries Department, Friends of the Smokies Fisheries Scholarship Fund or other youth educational conservation projects. The Little River Chapter of Trout Unlimited sponsors this event as our major fundraiser and annual festival. This year the event will be one of the largest venues for fly anglers in the Southeast United States.
Some of the best fly tyers from our area will be demonstrating throughout the two day event. Last year we had 8 tyers performing at one time all weekend. It’s free and the tyers are specialized in many different types of fly tying such as trout, bass, panfish and saltwater.
In 2010 they donated $45,000 to the National Park Service Officals.
