Corps breaks levee as water rising elsewhere

Corps breaks levee as water rising elsewhere

May 3rd, 2011 by JIM SALTER and JIM SUHR, Associated Press in News

In this image taken from video, an explosion lights up the night sky as the the U.S. Army Corps of Engineers blows an 11,000 foot hole in the Birds Point levee in Mississippi County, Mo. on Monday, May 2, 2011. Army Corps of Engineers' Maj. Gen. Michael Walsh gave the order to blow a two-mile hole into the Birds Point levee in southeast Missouri, which will flood 130,000 acres of farmland in Missouri's Mississippi County but protect nearby Cairo, Ill.

WYATT, Mo. (AP) - A few momentary blasts, flashes of orange light, and the Mississippi River began pouring through a wide hole in a Missouri levee, intentionally blown open by the Army Corps of Engineers in the hope of saving a small Illinois town.

Even as the corps' carried out its bid to protect Cairo, Ill., floodwaters are rising downriver, including in Memphis, Tenn. And the breach in the Birds Point levee wasn't expected to ease those flooding concerns.

The Army Corps exploded the Birds Point levee after nightfall Monday, sacrificing 130,000 acres of rich farmland and about 100 homes in Missouri to spare the Illinois town of 2,800 residents that is at the confluence of the Ohio and Mississippi rivers.

The breach should reduce water levels in Cairo and on another threatened levee in northern Kentucky, by up to 4 feet by late Tuesday or early Wednesday, corps officials say.

Flooding concerns also were widespread in western Tennessee, where tributaries were backed up due to heavy rains and the bulging Mississippi River. Streets in suburban Memphis were blocked, and some 175 people filled a church gymnasium to brace for potential record flooding.

Walsh has said he might also make use of other downstream "floodways" - basins surrounded by levees that can be blown open to divert floodwaters.

Among those that could be tapped are the 58-year-old Morganza floodway near Morgan City, La., and the Bonnet Carre floodway about 30 miles north of New Orleans. The Morganza has been pressed into service just once, in 1973. The Bonnet Carre, which was christened in 1932, has been opened up nine times since 1937, the most recent in 2008.

Officials in Louisiana and Mississippi are warning that the river could bring a surge of water unseen since 1927.

The corps has said about 241 miles of levees along the Mississippi River between Cape Girardeau, Mo., and the Gulf of Mexico need to be made taller or strengthened. George Sills, a former Army Corps engineer and levee expert in Vicksburg, Miss., said the volume of water moving down the river would test the levee system south of Memphis into Louisiana.

"It's been a long time since we've seen a major flood down the Mississippi River," Sills said. "This is the highest river in Vicksburg, Miss., since 1927. There will be water coming by here that most people have never seen in their lifetime."

Engineers carried out the blast on the Missouri levee after spending hours pumping liquid explosives into the floodwall. The blast allowed water to pour into the river basin like a bathtub. Two subsequent blasts further south on the levee, both scheduled for Tuesday morning, were aimed at allowing some of that water to escape back into the Mississippi.

The blasts became necessary after another onslaught of rain Sunday and Monday. Parts of southern Missouri have received more than 20 inches of rain in the past 11 days.

Corps Maj. Gen. Michael Walsh, who made the decision to blast the levee, said that with the Ohio River now expected to reach 63 feet in Cairo - just a foot under the top of the floodwall - he had no choice.

"Making this decision is not easy or hard," Walsh said. "It's simply grave, because the decision leads to loss of property and livelihood, either in a floodway or in an area that was not designed to flood."

Missouri officials fought hard to stop the plan, filing court actions all the way to the U.S. Supreme Court. Rep. Jo Anne Emerson, a Republican from nearby Cape Girardeau, stood beside Walsh as he announced his decision Monday, but she was clearly unhappy.

"We're uprooting families that have been here six generations and you don't even know if it's going to work," said Rep. she said.

The explosion came just before 10 p.m., lasting only a few seconds, with reporters watching from about a half mile off the river.

In largely evacuated Cairo, police Chief Gary Hankins watched the orange flashes and was hopeful.

"We had periods here where there were lulls, but it seems like lately we couldn't catch a break," he said. "Maybe it seems now like we might be at a turning point. This sort of makes it easier to be optimistic."

On the other side of the river, Mississippi County, Mo., commissioner Robert Jackson said farewell to his family's 1,500 acres of farmland. But he also tried to stay positive.

"We can't start drying up until we finish getting wet," he said. "I hope this mission accomplishes what they wanted it to, and the sun will shine again."
