Old River

Lettsworth, Pointe Coupee County · Louisiana

Old River is a story of repairs. The Army Corps of Engineers finished its control complex in 1963 and put it into operation in 1964, but the 1973 flood nearly caused it to fail. An auxiliary structure was added in 1986 to relieve the original gates, and a hydroelectric station followed in 1990. The reason is a threat, not a convenience: if the Mississippi broke into the shorter, steeper Atchafalaya route, a new delta would form south of Morgan City, and Baton Rouge and New Orleans would lose much of their river flow, with serious economic effects.
