Morganza Spillway Will Be Opened for First Time in 38 Years
May 15th, 2011Via: Weather Channel / AP:
Louisiana Gov. Bobby Jindal says federal officials have been given approval to open a Louisiana spillway as early as Saturday to avert a Mississippi River disaster in places like Baton Rouge and New Orleans.
Jindal said Friday that the Army Corps of Engineers had received permission to open the Morganza spillway for the first time in 38 years to relieve pressure on river levees. The corps says it will open the spillway when the river flow reaches a certain point, but an exact timing wasn’t known. However, that flow rate is expected to happen Saturday.
…
If Morganza is opened, water would flow 20 miles south into the Atchafalaya River. From there it would roll on to the Gulf of Mexico, flooding swamps and croplands.
…
The river’s rise may also force the closing of the river to shipping, from Baton Rouge to the mouth of the Mississippi, as early as next week. That would cause grain barges from the heartland to stack up along with other commodities.
If the portion is closed, the U.S. economy could lose hundreds of millions of dollars a day. In 2008, a 100-mile stretch of the river was closed for six days after a tugboat collided with a tanker, spilling about 500,000 gallons of fuel. The Port of New Orleans estimated the shutdown cost the economy up to $275 million a day.
With crop prices soaring, farmers along the lower Mississippi River had been expecting a big year, maybe even a huge one. Now, many are facing ruin, with floodwaters swallowing up corn, cotton, rice and soybean fields.
And even more farmland will be drowned when the spillway is opened. Unlocking the spillway would inundate Louisiana Cajun country with as much as 25 feet of water but would ease the pressure on levees downstream, averting a potentially bigger disaster in New Orleans and Baton Rouge.
Trouble has already found the fields in far northeastern Louisiana, where Tap Parker and about 50 other farmers filled and stacked massive sandbags along an old levee to no avail. The Mississippi flowed over the top Thursday, and nearly 19 square miles of soybeans and corn, known in the industry as “green gold,” was lost.
…
While the Mississippi River flooding has not had any immediate impact on prices in the supermarket, the long-term effects are still unknown. A full damage assessment can’t be made until the water has receded in many places.
Some of the estimates have been dire, though.
More than 1,500 square miles of farmland in Arkansas, which produces about half of the nation’s rice, have been swamped over the past few weeks. In Missouri, where a levee was intentionally blown open to ease the flood threat in the town of Cairo, Ill., more than 200 square miles of croplands were submerged, damage that will probably exceed $100 million. More than 2,100 square miles could flood in Mississippi.
