Why It’s #1: America’s Most Endangered River of 2018

The Yazoo Pumps would cost taxpayers more than $300 million and would drain and destroy an area of wetlands roughly the size of all five New York City boroughs. Help us force Congress to stop this plan.

Senator John McCain called it “one of the worst projects ever conceived by Congress.”

Former Secretary of the Interior Bruce Babbitt called it “godawful, cockamamie.”

They were talking about the Yazoo Pumps, an Army Corps boondoggle that would devastate Mississippi’s Big Sunflower River and cost taxpayers hundreds of millions of dollars.

Thanks to President Trump and his allies in Congress, this terrible project is back and it poses such a threat that we placed the Big Sunflower River at the top of the list of America’s Most Endangered Rivers® of 2018.

The Big Sunflower River is a special place…

The Yazoo Pumps project would cause a mind-boggling amount of damage…

The Yazoo Pumps project would cost taxpayers at least $300 million. That’s a lot of money…

It’s time to stop this terrible project once and for all.


In addition to the Big Sunflower River, America’s Most Endangered Rivers of 2018 is a snapshot of some of our nation’s most beloved and iconic rivers in the crosshairs. The list includes:

In our many years of issuing the America’s Most Endangered Rivers report, we’ve seldom seen a collection of threats this severe, or an administration so bent on undermining and reversing protections for clean water, rivers and public health.

Your support is vital as we fight for America’s Most Endangered Rivers of 2018, and rivers nationwide.


Thank you for standing with us.

  1. I need some clarification about what the proposed Yazoo Backwater Area Pumps Project would actually do, and specifically how it would affect the wetlands and wildlife habitat surrounding the Yazoo and Big Sunflower Rivers. I think it would be helpful if, rather than employing the language of outrage and hyperbole, we could provide some maps and some specific descriptions of the lands that would be affected and precisely how they would be affected.

    As I presently understand it, at the confluence of the Yazoo and the Mississippi Rivers a control structure has already been built, with gates that can be closed during high-water events in order to prevent the Mississippi from back-flooding up the Yazoo flood plain. The problem is that when the gates are closed, the flow of the Yazoo is blocked and thus begins to inundate its own flood plain. The proposed project would enable the Yazoo’s water to be pumped over this structure and into the Mississippi, thus preventing or mitigating the flooding of the farmlands along the Yazoo flood plain. With a capacity of 14,000 cfs, it would be one of the largest such pump stations ever built.

    Considering the amount of money that has already been spent on the project to date, it would seem that without the pumps the already-completed structure would be rendered nothing more than an expensive white elephant. So I understand why Mississippi’s congressional delegation would want this project completed.

    But what, specifically, is so objectionable about this project from a conservation standpoint? I’m not wanting to come off as contrarian or some sort of troll; I really just want to have a better understanding. I get the objections based on the cost – this project would be quite expensive, and it may not pass the cost/benefits test, since only a small number of people would actually benefit economically from it. I also get the objections over process – that the present bill would effectively override the Clean Water Act and exempt the project from judicial review. But as for the environmental impact, I’m still trying to educate myself. How would the wetlands and wildlife habitat of the Yazoo and Big Sunflower Rivers be destroyed or otherwise altered? And to what degree? How would simply pumping the Yazoo’s waters over the barrier when the gates are closed destroy so many acres of wetlands and so much wildlife habitat upriver? And would they be permanently destroyed, or merely impacted and deprived of new deposition by the altered flow pattern?

    1. Thanks for your comment and questions. You can learn more about the Yazoo Pumps project and it’s damage to the Big Sunflower River by reading the full report at americanrivers.org/bigsunflower. We will also have a series of blogs coming over the next month that will dive into the environmental harm of the Yazoo Pumps, so please be on the lookout for those.

      1. Rebecca, why was my comment not allowed? Why are you hiding the real benefits to life and property the pumps would help protect?

      2. Hi “Common Sense”,

        There must have been an accident in our system, we’ll work to restore your comment and respond to it with information on how the Yazoo Pumps will indeed harm wetlands, fish, and wildlife on the Big Sunflower River. Sorry about that!
