The Rocky River is a tributary of the Yadkin River in North Carolina, spanning 90 miles from its headwaters in the Uwharrie Mountains to the confluence with the Yadkin. The river was historically used for transportation and power, with mills and factories along its banks. Today, the river is primarily used for recreation, with popular activities including fishing, kayaking, and hiking along the Riverwalk trail. The river is fed by several small tributaries and is home to several species of fish, including largemouth bass, bluegill, and catfish. The river is also home to several reservoirs, including Falls Reservoir and Lake Norman, which serve as sources of hydroelectric power and drinking water for nearby communities. The river and its ecosystem are protected by various organizations, including the Rocky River Heritage Foundation and the North Carolina Wildlife Resources Commission.
