Old River Control Structure such that the volume of the two rivers is split 70%/30%, respectively, as measured at the latitude of Red River Landing. This flow split was not based on science, but rather was based on the approximate flow allocation between the two rivers that existed at the time of construction. Water diverted at Old River flows into the Atchafalaya Basin, first entering the Red River, then continuing down the Atchafalaya River to the Gulf of Mexico, bypassing Baton Rouge and New Orleans (see diagram). The Morganza Floodway, between the Mississippi and the Atchafalaya Basin nearby downstream, is normally closed, but can
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
