Our transcription: In 1954, as the result of the Army Corps Report, the United States Congress authorized the Old River Control Project.
Essentially, this funded the construction of a series of control structures and channels all situated in the Old River Area.
Under the plan, the flow of water and sediment between the Mississippi and the Atchafalaya was to remain at its then current rate, a 70/30 split.
Thirty percent of the combined discharge of the Mississippi and Red Rivers was to flow into the Atchafalaya, while the remaining 70 percent would be kept within the Mississippi itself.
