Corps of Engineers Flood Inundation Map

In partnership with state and local leaders, the Corps has developed an Inundation Map to depict anticipated impacts from operation of the Morganza Floodway. As floodwaters progress through the Morganza Floodway to the Gulf of Mexico, the height of the water could reach between five (5) and upwards of twenty-five (25) feet above ground elevation, causing widespread flooding and inundation.

What Failure of the Morganza Spillway Would Mean To La. Life As We Know It
by Steve Wilkerson on Tuesday, May 10, 2011 at 2:18am

The Morganza Spillway flood control structure in Pointe Coupee Parish could open as early as Saturday but it could be delayed until Tuesday, May 17, depending on conditions, the Mississippi River Commission president said Monday. “If we operate Morganza, there won’t be overtopping. If we don’t operate Morganza … about three miles south of Baton Rouge, we will have significant overtopping there. LSU and a couple of other significant infrastructure would be inundated,” said U.S. Army Maj. General Michael Walsh of the Army Corps of Engineers.[1]

The Morganza Spillway was opened for the first and only time in 1973 to relieve pressure from the Old River Control Structure (ORCS). [2][3] The spillway received minor scouring and slight damage to the stilling basin. After the 1973 flood, the structure was restored to its original condition.

In 2008, a flood caused portions of the levee at the spillway to deteriorate and sent floodwaters into cropland located within the floodway. It is because of this damage to the levées around the spillway and the extent to which the structure itself was undermined by just the '73 test that the Morganza Spillway has never been opened since, though it would have been useful during several subsequent years to relieve pressure on the Old River Control Structure.

Studies by the Army Corps of Engineers after the test determined that once opened, it would likely never close again, and could be ripped from its footings, allowing the Mississippi River to jump its banks and flow primarily through the Atchafalaya Basin.

While this would leave New Orleans, Baton Rouge, and the Port of New Orleans practically high and dry, the Atchafalaya Basin would become the the main artery of the Mississippi River below Morganza and several cities along the bucolic Atchafalaya River would be flooded and a new delta would begin forming immediately. The failure of the Morganza structure would be disastrous beyond imagination for the residents of south Louisiana and international commerce

I dont think the average person realizes what Louisiana is up against right now. And of course, Miss River commerce will impact the entire nation.

(Hey Smash, I tried to call you while ago, return your call. good to hear from you brother. And yeah... we're boiling bugs again. Will shout at ya
later, I have 2 gigs to get ready for, and Im on the air. )

Think that's bad...

I went to Acme Oyster house today to get an oyster poboy and they were $16.50 for a regular poboy.
Needless to say I had to get the Shrimp for $9.95.

I blame Obama.

I just drove out to the Butterfly (for those not in New Orleans, it's a riverside park) and looked at the river... it is HIGH. At least 10 feet above where it usually is, and my guess was that it is moving about 15 miles an hour as opposed to its usual four.... if that's anywhere close to correct it would mean there's about 5 times as much water just flowing through N.O. as you see on a typical day. Kind of scary for those of us who live here.

Im scared for you, dude. I saw this picture: (attached)

I know how high that levee is, and how far over street level the river is, and how much rock should be showing. freaky. You guys, along with those in the Basin are in our prayers.
