About Clarion River
The Clarion River, a National Wild and Scenic River in North-Central Pennsylvania, offers diverse fly fishing across its main stem, East Branch tailwater, and West Branch freestone sections. This picturesque river, flowing through the Allegheny National Forest and several state parks, is renowned for its significant brown trout population, alongside native brook trout and smallmouth bass. Anglers can anticipate excellent hatches of Green Drakes, Caddis, Cahills, March Browns, and Sulphurs. The East Branch tailwater provides opportunities for wild brown and rainbow trout in a serene setting, while an eight-mile "All Tackle Trophy Water" stretch from Johnsonburg to Ridgway boasts abundant pools and riffles ideal for targeting larger brown trout and smallmouth bass. Much of the river is accessible from the bank, with a 9-foot 5-weight rod well-suited for dry fly and nymphing, and a 6-weight recommended for streamers.
