Bryan Piazza is the director of freshwater and marine science for The Nature Conservancy in Louisiana.
I’m a Nature Conservancy ecologist, a father and a husband, and a Louisiana resident. So what does the impending Mississippi River flood mean to me?
As a father and husband, I’m thinking: 21 feet, 42 feet, 52 feet.
21 feet: The elevation above sea level of my son’s daycare center on LSU’s campus, which has a great view of the Mississippi River Levee. I know….I checked the FEMA flood maps. Oh, man, I think. That’s not good.
42 feet: That’s the level the river is as I’m checking the flood map. It’s been this high before, but it’s forecast to crest over 5 feet higher and within 2 feet of the top of the levee. We’re going to have to make other plans for my son soon.
52 feet: That’s the elevation of my house in Baton Rouge about three miles from the river where my wife and new son are. It’ll be ok.
As an ecologist, I’m completely fascinated with this flood event and the strain of the river against its containment. In fact, I moved to Louisiana from Wisconsin over 15 years ago to study river flooding and river-floodplain interaction. And I’ve been knee-deep in its muddy water since then, learning everything I can about it and working on its behalf.
Right now, it comes down to containing this flood. As a father and a homeowner, I hope that the river’s containment is strong and sound. So far that containment is sparing my family from flooding, but somewhere, some other father, some other homeowner is not so lucky.
But after the flood is over, we’re going to need to talk as a state and a nation about more than just containment of natural and man-made disasters like those we’ve seen here in south Louisiana over the last five years – hurricanes, the oil spill, and now this river flood.
In a place where we often talk of elevation in inches instead of feet, we see the need to use the power of natural systems to protect people, not just in our state, but throughout the Mississippi River Basin. We’re trying to answer that call in The Nature Conservancy in Louisiana by working on innovative solutions to some of our toughest challenges.
- Our Mollicy Farms Floodplain Restoration project, where we joined with partners to breach 17 miles of levee and reconnect 90,000 acres of floodplain and adjacent watershed back to the Ouachita River, is the largest river-floodplain reconnection project in the country. That not only means habitat for wildlife, it means floodwater has a place to go before reaching the town of Monroe, Louisiana.
- We’re also hard at work developing science-based conservation and restoration strategies in the Atchafalaya River Basin. This massive natural area is not only a million-acre American treasure, but it is also major outlet for floodwaters and one of the major relief valves that protect millions of people on the Lower Mississippi River from flooding.
- And we’re restoring oyster reefs to protect eroding shorelines and restore the suite of services that oysters provide for nature and people.
Our future in south Louisiana and across the Mississippi basin depends on expanding these practical solutions to scale so that we don’t have to rely so heavily on hard containment to protect our families and property. On that point, the ecologist and father in me totally agree.
