Our transcription: The 1973 flood demonstrated how suddenly the River's conditions could change.
The Corps realized it had to more closely monitor the 70/30 ratio of flow between the Mississippi and the Atchafalaya.
Until 1973, the Corps only looked at the average annual flow.
As a result of the flood, the flow rate is currently monitored each and every day.
It is the New Orleans District Office of the Army Corps of Engineers, which oversees the day-to-day operation of the Control Structures.
The flow data from the Structures is reviewed here, and river conditions are closely monitored.
Based on these data, major decisions are made about which gates are to be opened or closed.
