Terrebonne Parish at risk with Mississippi River flooding

With the opening of the Morganza Spillway beginning today, low lying areas in Terrebonne Parish are almost certainly going to go under water.   This includes Gibson, Bayou Black where several swamp tours operate, Southdown Mandalay, and Bull Run Road where our USDA Farm is located.  Beyond this, it is a wide open question as to how serious flooding will get in Terrebonne Parish as shown by the Army Corps of Engineers map at left.  We are being assured by government officials that Houma should remain dry, but we all too keenly remember how levees didn't hold up in New Orleans during Hurricane Katrina.  It is not outside the realm of possibility that the Mississippi River could change course under a massive flooding situation, changing to the more direct and steeper flow through the Atchafalaya River to Morgan City, which is where it used to primarily flow, going back enough years.  Obviously, this would be catastrophic to all of the coastal Parishes in Southeastern Louisiana.  Peak flooding is expected in this area around May 23, a little over a week from now.
