Mississippi River Flooding
We think the Corps should operate the ORCC to increase the discharge as the river rises — and that Congress should authorize this. Now. This would lower flood crests, make floods shorter, and reduce the risk of levee failure — and a course change. It would also reduce batture and backwater flooding and the resulting economic and environmental damage on some 1.5 million acres in Mississippi and Louisiana. Time to change the flood control plan – before it’s too late.
Since 2016, Bigger Pie (BPF) has warned repeatedly that water reaches the Lower Mississippi River (MSR) faster than it can get out to the Gulf of Mexico (GOM). Isn’t it time to either remove the plugs in the Lower MSR or to open the other drain —Old River Control Structure?
Why is the river so high in July? Why has the MSR from below Natchez to north past Vicksburg been 4-5 ft. higher on average over the past decade during low water months than it was 50 years ago?
2019 will be a record for the last 80 years, possibly in modern times, for flood stage water in the Lower Mississippi River.
The Pumps will pour water out of the Delta’s boot over the levee at Vicksburg onto people below. They will make flooding higher and longer inside the levee. Landowners in the Delta outside the levee will benefit. Landowners inside the levee will suffer. The pumps won’t increase the discharge to the Gulf. They just pass the flood downriver onto someone else. That’s the history of other divisive Corps flood control projects. That’s why the river is full now.
Much of the Mississippi between Natchez and Venice, LA is below the surface of the Gulf of Mexico. A large portion of the river from Donaldsonville to Venice is below the BOTTOM of the entrance leading to the Gulf of Mexico.
You might guess flood stages would move from north to south in the Mid-to-Lower Mississippi River as the waters travel north to south to reach the Gulf of Mexico. You’d be wrong.
