KROTZ SPRINGS, La. —Less floodwater than initially thought will end up swamping Cajun towns and farms, officials said Monday. That’ll make the difference between wet or dry for some, but others — those who live in areas where up to 20 feet was expected — will still see flooded property.
"The crests have been lowered modestly in a number of places," Louisiana Gov. Bobby Jindal told reporters after being briefed by the Army Corps of Engineers. As a result, fewer flood gates at the Morganza Spillway will likely have to be opened.
But the possibility of "backwater flooding" for areas not protected by levees and earthen works was still high, he added. "We are still looking at a very significant amount of water," Jindal said. "We know it's going to impact households. We know it's going to impact families."
The Corps reported that Mississippi River floodwater "is not rising as quickly in the (Morganza) Spillway as they expected because their projections used 1973 data, which is not specifically geared to this exact situation, and because of drought conditions absorbing much of the water, which were not factored into their projections," Jindal's office said in a statement.
That slight piece of good news didn't stop crews and remaining residents from last-minute sandbagging and levee construction.
In towns like Amelia, about 100 miles south of the spillway that was opened Saturday, crews worked around the clock to build earthworks and reinforce levees ahead of water expected to reach the area by Tuesday.
"I hope they know what they are doing," said Hue Tran, who was watching the giant dump trucks.
The flooding earlier submerged parts of Memphis, Tenn., where President Barack Obama arrived on Monday to meet with impacted families before delivering a high school commencement address.
Other Louisiana towns, like Krotz Springs, Butte LaRose and Morgan City, also were making plans for severe flooding that could last for three weeks before the water works its way to the Gulf of Mexico.
A hand-painted sign in front a deserted Butte LaRose home said it all: "My slice of heaven force-flooded straight to hell. God help us all."
In Stephensville, a small town near Morgan City, Ronnie Wiggins and his neighbors furiously filled sandbags to protect their houses.
Wiggins had few kind words to say about the spillway's opening.
"It's all about saving Baton Rouge and New Orleans while they flood people down here," Wiggins said, pointing out that most people in his neighborhood did not carry flood insurance.
"So I guess it's all about saving the rich and burying the poor?" he asked.
In Krotz Springs, which will be among the first towns to feel the flood's effects, Kathy Reed-Eason spent the weekend moving her parents' belongings out of harm's way.
"My mom was crying," Reed-Eason said. "Mom said she'd go look at the river, and get out of the house."
About 2,000 people on Sunday were ordered to evacuate from St. Landry Parish, just south of Krotz Springs.

In Krotz Springs itself, locals were also urged to leave by Sunday afternoon.
Renee Ledoux cried when the National Guard and sheriff's deputies showed up at her front door.
But by the 5 p.m. deadline, the 44-year-old Ledoux and her boyfriend Billy Hanchett decided to ride it out one more night on air mattresses inside the empty home in Krotz Springs. They have a camper they plan to stay in on a friend's property outside the flood zone.
"We really don't want to go," Hanchett said. Ledoux added that she felt blessed that they had the camper because a lot of others have nowhere to go except shelters.
Despite the mandatory evacuation order, Krotz Springs town clerk Suzanne Bellau said it was unlikely the sheriff's office would force people to leave. For most, the worst part was wondering what may happen. National Guardsmen were building a second levee to bolster protection for the town.
"It's the unknown, that's the problem," Bellau said. "Is it going to come into their homes or not? And the people who are leaving, what are they coming back to?"
About 2,500 people live in the Morganza Spillway's flood path. Some 22,500 others, along with 11,000 buildings, could be affected by backwater flooding — the water pushed back into streams and tributaries that cannot flow normally into what will be an overwhelmed Atchafalaya River.
Some 3,000 square miles of land could be inundated in up to 20 feet of water for several weeks. When flows peak around May 22, the spillway will carry about 125,000 cubic feet per second, about one quarter of its capacity.

Monday marked the 10th time it has been opened since the structure was completed in 1931. The spillway diverts water from the Mississippi River to Lake Pontchartrain.
