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 to flow in the river's old natural channel as well. 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.Speer, Paul et al (1964).

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