The delta is home to many fish species and supports commercial and recreational fishing. The flow of water is affected by seasonal trends, including hurricane season and spring flooding. The delta also plays a vital role in preventing land loss in Louisiana. Interestingly, the Wax Lake Outlet was artificially created in the 1940s to divert water from the Atchafalaya River and prevent flooding in nearby areas. Today, it remains an important component of Louisiana's hydrology.
