The Rapid River in Western Maine is 3.2 miles long. Forming an outlet of the Rangeley chain of lakes, it begins at Lower Richardson. From Middle Dam to Lake Umbagog, it drops about 180 feet, making it one of the fastest falling rivers east of the Mississippi. It flows constantly, and with the help of the cool, oxygen-filled water released by Middle Dam, it creates the perfect habitat for trout — big trout. Three- to six-pound native brook trout can be found on the Rapid River along with landlocked salmon that were introduced in the late 19th century. It's a difficult river to get to, but for New Englanders used to pulling in ten-inch "brookies," the Rapid presents a rare opportunity to catch the trophy-sized fish of their dreams. From opening day in May until the end of the season in September, Aldro French of Rapid River Fly-Fishing guides trips on the river. The trout fishing on the Rapid is legendary and, being a guide, French is always asked the same questions: "What's the best week in May? What's the best week in June? What's the best week in July?" According to French, "It's the best week when you hit it and … you're in hog heaven when you hit it because you can catch 40 or 50 fish and half of them would be big fish." French lives and works out of his summer home, Forest Lodge, located near the Lower Dam. It's one of two sporting camps on the Rapid River and is the former home of Louise Dickinson Rich. It was there that the Maine author wrote her bestseller We Took to the Woods in 1942. In this segment, host Lawrence Pyne joins Aldro French on the Rapid River in search of trophy brook trout.
