The Yockanookany River, located in central Mississippi, stretches for 63 miles before emptying into the Pearl River. Historically, the river was used for transportation by Native Americans and early European settlers. Today, it is primarily used for recreation and agriculture. The river flows through several reservoirs, including the 9,000-acre Ross R. Barnett Reservoir, which was constructed in the 1960s to provide flood control, water supply, and recreational opportunities. The Mary Ricks Thornton Lake is another smaller reservoir used for recreation, located near the town of Canton. The Yockanookany is also an important water source for agricultural irrigation in the region. The river is popular for fishing, kayaking, and other outdoor activities, with several public access points and campgrounds available for visitors.
