The Morganza Spillway, a 4,159-foot (1,268 m) controlled spillway using a set of flood gates to control the volume of water entering the Morganza Floodway from the Mississippi River, consists of a concrete weir, two sluice gates, seventeen scour indicators, and 125 gated openings which can allow up to 600,000 cubic feet per second (17,000 cubic metres per second) of water to be diverted from ...

The complex also contains a navigation lock and the Sidney A. Murray Jr. Hydroelectric Station.
Scenario 2: Do not open the Morganza Spillway, and keep the Old River Control Structure at its routine operating level of only 30% of the Mississippi's flow; no additional water would be diverted Scenario 3: Do not open the Morganza Spillway, and open the Old River Control Structure somewhat more, which would divert an extra 150,000 cubic feet ...
