The Mississippi River is the nation’s most endangered river, a nationwide conservation group says, due to federal plans to chop flood-relief applications as extreme climate threats develop.

American Rivers, a nonprofit environmental advocacy group, has for the previous 40 years issued an annual record of U.S. rivers it views as most at-risk. The Mississippi’s place on the high comes as communities alongside the decrease river flooded from torrential rain in early April, and as Trump administration officers think about eliminating the Federal Emergency Administration Company, or FEMA, which helps state and native governments reply to disasters. 

The record calls consideration to the threats rivers face and prioritizes the rivers for which the general public can affect insurance policies that have an effect on their well-being, mentioned Mike Sertle, senior director for American Rivers’ Central Area. For the Mississippi River, he mentioned, the group’s purpose is to press the federal authorities to keep up a task in catastrophe reduction, which it says is crucial to safeguarding individuals in river communities. 

“We don’t disagree that issues must be reviewed and up to date,” Sertle mentioned. “However we additionally see there’s significance to holding the company.” 

The Mississippi River has all the time flooded. Whereas flooding threatens human buildings, it is a vital a part of the Mississippi River’s life cycle and really builds land. However specialists say floods are rising extra frequent, erratic and extreme attributable to local weather change. In 2019, the river’s most up-to-date main flood, water stayed at or above flood stage for months and brought about $20 billion in harm. 

FEMA assists communities throughout floods and different kinds of disasters, offers funds for restoration and oversees preparedness efforts, like its flood maps that predict dangers in several areas. And it’s doing so extra usually as we speak. A January 2025 report back to Congress discovered that the typical variety of main catastrophe declarations has elevated by 61% from the Nineteen Eighties and Nineteen Nineties, partly attributable to local weather change. 

However FEMA has confronted broad criticism for not shifting rapidly sufficient after disasters and not serving to catastrophe survivors equally. President Donald Trump has floated the concept of dismantling the company and in February the company fired greater than 200 of its staffers as a part of Trump’s push to shrink the dimensions and scope of the federal authorities. The White Home didn’t touch upon the American Rivers’ report’s criticism of those actions. 

FEMA is very vital for coordinating flooding responses alongside the Mississippi River as a result of it touches so many states on its journey to the Gulf, mentioned Kelly McGinnis, government director of the environmental advocacy group One Mississippi. 

She and Sertle each described vital room for enchancment in how FEMA operates, together with dashing up timelines for getting assist to communities. The American Rivers report says a simpler and environment friendly FEMA is crucial for flood administration because the cycle of drought and flooding on the Mississippi River turns into more and more excessive.

Cuts to different federally funded flood administration companies will possible affect the Mississippi River past the risk to FEMA, the American Rivers report famous.

“FEMA performs a crucial function in serving to tackle points within the aftermath of the flood,” mentioned Alisha Renfro, coastal scientist with the Nationwide Wildlife Federation. “On the entrance finish, it’s actually concerning the Military Corps of Engineers and their funds is being threatened as properly.”

In March, a stopgap invoice to fund the federal authorities by Sept. 30 slashed $1.4 billion from the Military Corps of Engineers’ development funds, which funds hurricane and flood mitigation tasks. 

With funds losses to each FEMA and the Military Corps, mitigation grant applications to deal with riverine flooding could possibly be impacted considerably. In response to FEMA, each federal greenback spent on flood mitigation yields $7 in advantages. 

American Rivers’ announcement comes as states alongside the decrease Mississippi are experiencing and bracing for flooding from heavy rains upriver. Vicksburg, Mississippi officers are reinforcing flood partitions as they look ahead to floodwaters to reach. In Louisiana, the Military Corps is patrolling New Orleans levees for issues. On Monday, the brand new Bayou Chene floodgate was closed for the primary time attributable to excessive water to guard a number of parishes from backwater flooding because the Atchafalaya River continues to rise.

The Mississippi has made the endangered rivers record within the latest previous for different issues. In 2022, your entire river appeared on the record due to air pollution and habitat loss, and in 2020, threats from local weather change and improvement landed the higher Mississippi at primary.

The river’s continued appearances on the record present that there isn’t sufficient progress being made on its largest challenges, McGinnis mentioned. 

However though the excellence could also be unfavourable, she mentioned it’s excuse to place river points within the highlight. 

“I feel it’s very helpful to be having these vital conversations,” McGinnis mentioned, “so we are able to hopefully actually start to vary how we deal with huge rivers.”
