Getting the Recipe Right: How Adaptive Management Can Help Optimize Diversions

As the weather begins to cool down in Louisiana, there is no better time to talk about everyone’s favorite dish: a nice warm bowl of gumbo. Whether your favorite is seafood or chicken and sausage, several steps go into perfecting a gumbo recipe. “Coastal restoration” might not immediately come to mind when you think about a perfect gumbo. But in reality, perfecting the operation of Louisiana’s sediment diversions is a lot like getting a classic gumbo recipe tried, true, and …

Upriver Diversions Can Reduce Impacts of Bonnet Carré Spillway

02.07.2022 | Posted by

New research shows river diversions can restore vital wetlands and reduce impacts of Bonnet Carré Spillway openings Climate change is causing more intense rainfall across the Mississippi River Basin resulting in more river floods and more frequent use of the Bonnet Carré Spillway. The spillway is a massive flood control structure operated by the U.S. Army Corps of Engineers when the river reaches a certain flood stage to reduce pressure on the levees and prevent catastrophic flooding to more than …

Skip to a section 1. CLAIM: The Mid-Barataria sediment diversion is being imposed upon residents who do not want it. 2. CLAIM: Dolphins are a “canary in a coal mine” that will become “virtually extinct” because of the diversion. 3. CLAIM: The diversion will destroy our way of life and jobs in Plaquemines Parish. 4. CLAIM: We can “dredge” our way out of our coastal land loss crisis. 5. CLAIM: “It’s not a freshwater diversion. It’s a polluted water diversion.” …

Without the Mid-Barataria Sediment Diversion, the Future for Louisiana’s Barataria Basin is Bleak

02.08.2021 | Posted by Rachel Rhode, Manager, Climate Resilient Coasts & Watersheds, Environmental Defense Fund

Louisiana’s land loss crisis is dire and will significantly worsen without investments in large-scale coastal restoration and protection projects. Since the 1930s, Louisiana has lost 2,000 square miles of coastal wetlands. Without action, the state could lose double that amount — an additional 4,000 square miles of land – in the next 50 years. This future scenario, commonly referred to as Future Without Action (FWOA), underscores why Louisiana has literally no time to lose in constructing coastal projects that can …

5 Places in Plaquemines Parish Building Land Because of the Mississippi River

10.09.2018 | Posted by Alisha Renfro, Coastal Scientist, Mississippi River Delta Restoration Program, National Wildlife Federation

A river runs through Plaquemines Parish, but it’s not just any river. It’s one of the largest in the world – the Mighty Mississippi. The river and its distributaries built Plaquemines Parish over the last 1,000 years, depositing sediment and building thousands of acres of highly productive wetlands. Levees, built along the river for navigation and flood protection, have helped communities in the parish to flourish but have also nearly completely cut off the river from the delta it once …

A Cornerstone for Coastal Restoration: The Mid-Barataria Sediment Diversion

09.12.2018 | Posted by Rachel Rhode, Manager, Climate Resilient Coasts & Watersheds, Environmental Defense Fund

To restore Louisiana’s coast, we need a suite of large-scale restoration projects across the coast working together to deliver maximum benefits to reduce land loss, restore ecosystems, and maintain healthy and diverse habitat. In our “Restoration Project Highlights” series, we take a deeper look at specific projects from our list of Priority Projects, highlighting why they’re needed and hearing local perspectives on importance.

Facing Continued Land Loss, Mississippi River Delta Needs Diversions More Than Ever

04.12.2018 | Posted by

MODIS Imagery of Louisiana on May 6, 2017 from Louisiana State University’s Earth Scan Laboratory (https://www.esl.lsu.edu/imagery/MODIS/2017/05/6/) showing the sediment plume from the Mississippi River. The future of the Mississippi River Delta will likely look drastically different than it does now. As sea level rise increases, we need to be smart about where and how we build land along Louisiana’s coast. A viable future for coastal Louisiana means a smaller delta, and using sediment diversions to strategically build and maintain land …
