BUTTE LAROSE, La. —In the latest agonizing decision along the swollen Mississippi River, federal engineers are close to opening a massive spillway that would protect Baton Rouge and New Orleans but flood hundreds of thousands of acres in Louisiana Cajun country.
With that threat looming, some 25,000 people in an area known for small farms, fish camps, crawfish and a drawling French dialect are hurriedly packing their things and worrying that their homes and way of life might soon be drowned.
People in this riverfront community gathered at their volunteer fire station to hear a man dressed in Army fatigues deliver an ominous flood forecast.
Col. Ed Fleming warned this week that projections by the Army Corps of Engineers call for the station to be inundated by up to 15 feet of water. The crowd let out a collective gasp.
"From the ground?" an incredulous resident shouted at the meeting.
"From the ground," replied Fleming, head of the corps' New Orleans district.
A few skeptics in the audience scoffed at the projection, but many others were shaken.
The corps could open the Morganza floodway north of Baton Rouge as early as this weekend, a move that would relieve pressure on the city's levee system.
Opening the spillway gates for the first time in 38 years will unleash the Mississippi on a wild ride south to the Gulf of Mexico through the Atchafalaya River and divert floodwater from the river into the basin's swamplands, backwater lakes and bayous. Several thousand homes would be at risk of flooding.
Even if engineers decide against opening the spillway, no one seems to doubt that a major flood is bound for Butte LaRose, Krotz Springs, the oil-and-seafood hub of Morgan City and other swampland communities in the Atchafalaya Basin.
The Morganza and the nearby Old River Control Structure were built in the 1950s to keep the Mississippi on its current course through New Orleans, one of the world's busiest ports. If the river rises much higher at New Orleans, the Coast Guard said Thursday that it would consider restrictions on shipping, which could include closing the channel to the largest, heaviest ships.
