Mississippi River flooding: Army engineers open Morganza Spillway, severe flooding threatens
MORGANZA, La. (AP) — Water from the inflated Mississippi River gushed through a floodgate Saturday for the first time in nearly four decades and headed toward thousands of homes and farmland in the Cajun countryside, threatening to slowly submerge the land under water up to 25 feet deep.
As the gate was raised, the river poured out like a waterfall, at times spraying 6 feet into the air. Fish jumped or were hurled through the white froth and within 30 minutes, 100 acres of what was dry land was under about a foot of water.
The opening of the Morganza spillway diverted water from Baton Rouge and New Orleans, and the numerous oil refineries and chemical plants along the lower reaches of the Mississippi. Shifting the water away from the cities will ease the strain on downriver levees and thwart potential flooding in New Orleans that could have been much worse than during Hurricane Katrina.
"We're using every flood control tool we have in the system," Army Corps of Engineers Maj. Gen. Michael Walsh said during a news conference on the dry side of the spillway, before the bay was opened.
The Morganza spillway is part of a system of locks and levees built following the great flood of 1927, which killed hundreds and left many more without homes. When the Morganza opened Saturday, it was the first time three flood-control systems have been unlocked at the same time along the Mississippi River, a sign of just how historic the current flooding has been.
Earlier this month, the corps intentionally blew holes into a levee in Missouri to employ a similar cities-first strategy, and it also opened a spillway northwest of New Orleans.
Snowmelt and heavy rain swelled the Mississippi, and the river has peaked at levels not seen in 70 years.
In Krotz Springs, La., one of the towns in the Atchafalaya River basin bracing for floodwaters, phones at the local police department rang nonstop as residents sought information on road closings and evacuation routes.
Like so many other residents downstream of the Morganza, Monita Reed, 56, recalled the last time it was opened in 1973.
"We could sit in our yard and hear the water," she said as workers constructed a makeshift levee of sandbags and soil-filled mesh boxes in hopes of protecting the 240 homes in her subdivision.
Low-lying areas of St. Landry Parish south of U.S. Highway 190 have been put under a mandatory evacuation order. St. Landry Parish President Don Menard said the order takes effect at 7 a.m. Sunday and includes areas within the Atchafalaya River Basin, which is expected to flood.
About 25,000 people and 11,000 structures could be affected by the oncoming water, and some people living in the threatened stretch of countryside — an area known for fish camps and a drawling French dialect — have already fled. Reed's family packed her furniture, clothing and pictures in a rental truck and a relative's trailer.
"I'm just going to move and store my stuff. I'm going to stay here until they tell us to leave," she said. "Hopefully, we won't see much water and then I can move back in. "
It took about 15 minutes for the one 28-foot gate to be raised in the middle of the spillway. Several hours will pass before any of the water hits sparsely populated communities, but residents nearby have been told to go.
