Frequently Asked Questions
Can I paddle the Duck River?
Yes. The Duck River is popular for canoeing and kayaking, with several outfitters offering guided trips and canoe rentals. The gentle current makes it accessible to beginners, and the clear water provides excellent visibility for observing aquatic life.
Why is the Duck River so biodiverse?
The Duck River is free-flowing for most of its length, although TVA’s Normandy Dam impounds an upper section. Free-flowing stretches keep the riffle-pool habitats that fish and mussels need. The river also flows through varied geology, which creates varied substrates.
