From Wikipedia, The Free Encyclopedia: The Old River Control Structure (ORCS) is a floodgate system located in a branch of the Mississippi River in central Louisiana. It regulates the flow of water leaving the Mississippi into the Atchafalaya River, thereby preventing the Mississippi river from changing course. Completed in 1963, the complex was built by the U.S. Army Corps of Engineers in a side channel of the Mississippi known as Old River, between the Mississippis current channel and the Atchafalaya Basin, a former channel of the Mississippi.
