The Lower Mississippi River Comprehensive Management Study moves forward despite slashed budget
More than 50 fisheries biologists, hydrologists, foresters, engineers, private landowners, wetland ecologists, recreational and commercial fishermen and state and federal agency staff from Wildlife and Fisheries, Army Corps of Engineers and the United States Geological Survey gathered in Lafayette in April 2025 to discuss how to improve the Atchafalaya Basin.
Organized by the non-profit habitat conservation organization The Nature Conservancy and the Corps of Engineers, the group was selected to find some consensus on ways to help improve fisheries, tree health and water quality in the Atchafalaya while limiting sedimentation and the spread of invasive species in the lower river’s largest swamp.
The timing of the meeting was perfect, considering the Corps was in the middle of a Congressionally-mandated project called the Lower Mississippi River Comprehensive Management Study. The study, authorized by Congress in 2020 with extensive support from Louisiana lawmakers, told the Corps to look at issues affecting the Mississippi River from Missouri to the Gulf, everything from flood control and shipping to fisheries and wildlife habitat and wetland restoration.
Those who went to the two-day workshop left feeling like real progress was made. The wide-ranging opinions in the room didn’t always align, but there was general agreement that changing how much water was sent from the Mississippi River down the Atchafalaya River at certain times of the year could improve fisheries. Sediment traps could limit the silt that is clogging bayous and canals. Strategic cuts could be made in some canal and bayou banks to allow water to move into stagnant backwaters. It felt like a big step in the right direction.
Then, a month later, it was revealed the Lower Mississippi River Comprehensive Management Study had stopped. The remainder of the $25 million appropriated by Congress was an unceremonious victim of the broad, sweeping federal budget cuts applied with a chainsaw rather than a scalpel.
An important study
In general, the last thing anyone advocating for habitat restoration in the Lower Mississippi River wanted to see was another lengthy study. Large parts of Louisiana’s coast have washed away in the last 50 years while study after study dragged on and the costs of that land loss and the projects needed to slow and repair it exploded.
However, significant changes, and even slight tweaks, in management of the lower Mississippi River and its swamps, floodplains, fisheries, navigation channels and flood protection will require scientific support, public buy in and the backing of sound engineers. Perhaps more importantly, the money to make any of those changes comes only after public engagement and studies show it is needed.
In the case of the Atchafalaya Basin or any floodplain or swamp connected to the Lower River, it will literally take an act of Congress for changes in authorizations and the money needed to dredge sediment and change the operation at the Old River Control Structure to allow more water from the Mississippi to move down the Atchafalaya River.
Stopping the study didn’t just slow progress in Louisiana. Mississippians, Tennesseans and Arkansans wanted results as well. They’ve all seen habitats along the Mississippi River and its tributaries decline, leading to a loss in fisheries and waterfowl production over the last half century. They’ve also dealt with historic floods and periodic droughts and increased sedimentation that has limited access to the river for recreation and commerce.
What’s next?
The guarded optimism shared by those who participated in meetings conducted by the Corps throughout 2024 and early 2025 quickly turned into frustration. It seemed this could be another federal study started with promise and good intentions that would be shelved and produce no tangible improvements to fish and wildlife habitat and flood control.
However, thanks to Congressmen Troy Carter of Louisiana and Mike Ezell of Mississippi, both recreational fishermen, and four of their congressional colleagues, there may be hope the study continues towards its completion in 2027.
Carter and Ezell were the lead authors of a July 2, 2025 letter to the chairman of the House Energy and Water Appropriations Subcommittee urging it provide $7.5 million to continue the study, calling it “a pivotal opportunity to align navigation efficiency and safety, flood control systems, and restoration efforts to foster a healthier, safer Lower River system that benefits all stakeholders and river communities.”
Appropriators responded by releasing a budget in early January of this year that has $5 million directed to the Corps to continue working on the study Congressmen Carter and Ezell called “indispensable.” While not the full amount requested, it is certainly enough for the Corps’ New Orleans District to resume work.
Wading and weaving through federal bureaucracies and budget cuts and dealing with the frustrating timetables of Corps of Engineers studies is not something 99 percent of hunters and fishermen want to consider. They’d rather rig rods and reels and gas up boats, toss out decoy spreads and spend time with buddies and family on the water.
Reality is, though, if they want great places to hunt and fish along the Mississippi River and want invasive fish and vegetation controlled and, maybe, a well-maintained boat launch here and there, dealing with studies and budgets and state and federal agencies is part of the process.
Thankfully, there are a few elected officials in Washington willing to make the priorities of hunters and anglers throughout the Lower Mississippi River their priorities as well.
