RENA LARA, Miss. - Officials in a small town are trying to assure its 500 residents they are doing what they can to shore up the levee to protect them from the swollen Mississippi River.
"It's getting scary," said Rita Harris, 43, who lives in a tiny wooden house in the shadow of the levee in Rena Lara. "They won't let you go up there to look at the water."
The uneasiness is being felt all along the poverty-stricken Delta as oozing floodwaters from the Mississippi River and its tributaries spilled across farm fields, cut off churches, washed over roads and forced people from their homes Wednesday.
Some used boats to navigate flooded streets as the crest rolled slowly downstream, bringing misery to low-lying communities. About 600 homes have been flooded in the Delta in the past several days as the water rose toward some of the highest levels on record.
The flood crest is expected to push past the Delta by late next week.
Mississippi Gov. Haley Barbour urged people to get out if they think there is even a chance their homes will flood. He said there is no reason to believe a levee on the Yazoo River would fail, but if it did, 107 feet of water would flow over small towns.
"More than anything else, save your life and don't put at risk other people who might have to come in and save your lives," he said.
CBS News correspondent Mark Strassmann reports that there are about 300 homes in tiny Tunica Cutoff, an hour south of Memphis, and they have all been flooded, CBS News correspondent Mark Strassmann reports.
Other swamped communities may rebuild, but Tunica Cutoff may not. New housing codes mandate raising new homes above the 100-year flood plain. Most victims in Tunica had no flood insurance, and couldn't afford raising their homes. So here's their worry: Tunica Cutoff could be gone for good, flooded into history.
On Tuesday evening, nearly 200 Tunica Cutoff residents filled a civic center in Tunica city, demanding answers from officials on whether or not they would ever be allowed home, the Memphis Commercial Appeal reports.
Pepper Bradford, the Tunica County planner and flood plan administrator, told residents that those "whose homes are determined to be substantially damaged will have to comply with current elevated building codes if or when they are rebuilt, but residents will be allowed to return if they comply," the Appeal reports.
Farther downstream, Louisiana officials were awaiting an Army Corps of Engineers decision on whether to open the Morganza spillway to take the pressure off the levees protecting Baton Rouge and, downstream, New Orleans and the many oil refineries in between.
The Mississippi Delta, with a population of about 465,000, is a leaf-shaped expanse of rich soil between the Mississippi and Yazoo Rivers, extending about 200 miles from Memphis, Tenn., to Vicksburg, Miss. Along the way are towns whose names are familiar to Civil War buffs, aficionados of the blues, and scholars of the civil rights era: Clarksdale, Greenwood, Greenville and Yazoo City.
While some farms in the cotton-, rice- and corn-growing Delta are prosperous, there is also grinding poverty. Nine of the 11 counties that touch the Mississippi River in Mississippi have poverty rates at least double the national average of 13.5 percent, according to the U.S. Census Bureau.
The governor said the state is asking local officials to get in touch with people who might have no electricity and phones and thus no way to get word of the flooding.
"It's a tiny number, but we have to find them," Barbour said.
In Mississippi alone, floodwaters have destroyed at least 800 homes, Strassmann reports. Most people will rebuild. But almost no one in Tunica Cutoff had flood insurance. Like Betty Webb, they'll have to start over somewhere else.
"It's hard to face it, you know what I mean," she said. "If you haven't been there, you just don't know."
All 19 casinos along the river will be shut down by the end of the week, costing governments $13 million in taxes per month; 13,000 employees will be out of work.
Late Wednesday, President Barack Obama signed a disaster declaration for 14 counties in Mississippi because of the flooding. Housing and home repairs will be covered and low-interest loans to cover uninsured damage will be available.
In Greenville, Liz Jones, who is unemployed, lives on the second floor of a housing project and worries what might happen in the event of a levee break. She has no means of transportation.
"I got a baby and my mama. I don't know what we'd do about food and clothes and stuff," she said.
In Hollandale, one of the small rural towns in the Delta the governor warned might flood if the levee breaks, 62-year-old nursing home worker Geraldine Jackson fretted about what to do if she and her husband have to leave their red-brick house, where pieces of the roof have broken off and the white trim is peeling.
"I have relatives, but all my relatives live in the Delta, and the water's going to get them too," she said. "I'm just real messed up."
Swollen by weeks of heavy rain and snowmelt, the Mississippi River has been breaking high-water records that have stood since the 1920s and `30s. It is projected to crest at Vicksburg on May 19 and shatter the mark set there during the cataclysmic Great Flood of 1927. The crest is expected to reach New Orleans on May 23.
Even after the peak passes, water levels will remain high for weeks, and it could take months for flooded homes to dry out.
About 600,000 acres of cultivated row crops could flood, mainly winter wheat, corn, soybeans, cotton and rice, said Andy Prosser, spokesman with the Mississippi Department of Agriculture. Even if the levees hold, the state expects to lose $150 million to $200 million worth of crops, the governor said. Mississippi's catfish farmers could also be wiped out if the Yazoo floods their ponds and washes away their fish.
Many of the victims of the slowly unfolding disaster are poor people living perilously close to the water.
In the Memphis, Tenn., area, where the Mississippi crested Tuesday just inches short of the 1927 record, many of the flooded dwellings were mobile homes and one-story brick or wood buildings in low-lying, working-class neighborhoods unprotected by floodwalls or levees.
Maria Flores, her husband, Pedro Roman, and their four children ended up in a church shelter in south Memphis some 20 miles from their trailer in the Millington area of Shelby County. They lost a trailer in last year's flood, and it happened to them again this year.
Flores, who works as a baby sitter, and Roman, an unemployed day laborer, did not have disaster insurance and suspect their trailer is a total loss. At the shelter, they were receiving clothing and three meals a day and were sleeping on air mattresses in a room with 20 other people.
Flores said she stopped going to work because it was too far and she could not afford the gas. Roman seemed almost paralyzed by the uncertainty.
"People who have money have a better chance of getting back on their feet than poorer people," Flores said. "That's our problem."
