Yockanookany River in 2010

The Yockanookany River is a 78.4-mile-long (126.2 km)[1] river in central Mississippi in the United States.[2] It is a tributary of the Pearl River, which flows to the Gulf of Mexico.


The Yockanookany rises in Choctaw County on the west side of the town of Ackerman and flows generally southwest through Attala and Leake counties, past the towns of Weir, McCool, Ethel and Kosciusko, it flows into the Pearl River in southwestern Leake County.[3]

The Yockanookany's upper course through Choctaw and Attala counties was channelized in 1914 and the middle section was completed in 1928; in some of these areas, water continues also to flow in the river's old natural channel. Low-water stages at the Koscuisko gauge in 1960 were six feet higher than those of 1939 as the channel silted significantly during that period.[4]

Downstream of Kosciusko, the river is paralleled by the Natchez Trace Parkway.
