2019 mississippi river flood

The commercial fishing industry on the Gulf Coast has seen two major disasters in the last 15 years: Hurricane Katrina and the BP oil spill. Now, some fear we’re on the cusp of a third. The culprit: historic flooding from the Mississippi River.

The Army Corps of Engineers is expected to open the Morganza Flood Control Structure on Sunday to relieve flooding on the Mississippi River. For those who live and work downstream of the spillway, that means it’s time to get ready.

For this story, we’re going to take a trip down the floodway, north to south. We’ll start in the town of Morganza, and end up down near the Gulf, talking to people along the way.

Towns along the Upper Mississippi River are dealing with some of the worst flooding they’ve ever seen. Busted levees. Flooded downtowns. What does that mean for us in Louisiana? When should we be concerned, and when should we not be?

The Army Corps of Engineers expects to open the Bonnet Carre Spillway Friday afternoon.

Located upriver from New Orleans, the Bonnet Carre Spillway acts as a release valve for the Mississippi River. When the water reaches a flow of 1.25 million cubic feet per second, the Corps opens the spillway to divert some of that water into Lake Pontchartrain.

The Mississippi River has been at flood stage for months. Levees and spillways keep most homes and businesses safe and dry from the flood waters, but the high water still creates headaches for levee districts and industries like oil and gas, and fisheries.

This week on the Coastal News Roundup, WWNO coastal reporter Travis Lux went to find out how the river creates problems we can’t always see. WWNO’s Tegan Wendland got the details.
