Morganza Spillway Structure (ORCS), in use since 1963, where floodgates are routinely used to redirect the Mississippi's flow into the Atchafalaya River such that the volume of the two rivers is split 70%/30%, respectively, as measured at the latitude of Red River Landing. During the 1973 Mississippi flood, the ORCS was being damaged due to high flow rates, leading to the opening of the Morganza Spillway to help relieve this pressure. Subsequently, the nearby Old River Control Auxiliary Structure (ORCAS) was constructed, adding additional floodgates for use during major floods. The Morganza Spillway, about downriver from ORCS and ORCAS, is designed for
Battle of Stirling's Plantation Fordoche crossing followed the east bank of Bayou Fordoche, running west to a point about three miles from Morganza, then following a turn in the bayou, ran south three and a half miles to a loop in the bayou by Norwood’s plantation. Just west of Norwoods, the Opelousas Road forked to the northwest, crossed the Fordoche, and ran on to the Atchafalaya across from present day Melville, Louisiana. Shortly after leaving Morganza, the force encountered Confederate pickets and skirmished with them throughout the day until they reached the Norwood plantation, about six miles from the Archafalaya, where they went into
