The Mississippi River has been named “America’s Most Endangered River of 2025” by nonprofit American Rivers, highlighting increasing environmental and policy threats that could prove detrimental to both the river’s ecosystem and the millions of people who depend on it.
The designation was made as the Trump administration considers sweeping cuts to the Federal Emergency Management Agency (FEMA) and the National Flood Insurance Program. American Rivers argues that federal programs are crucial for flood risk management, disaster preparedness, and community resilience along the Mississippi River’s 2,320-mile stretch from Minnesota down to Louisiana.
“The Mississippi River is vital to our nation’s health, wealth, and security,” said Mike Sertle, Coastal Region Director for American Rivers. “We cannot turn our back on Mississippi River communities or the health of the river millions depend on at this critical time when they need unified direction instead of uncertainty at the national level.”
American Rivers’ report added that FEMA plays an essential role in reducing flood risks, supporting resilient development, and ensuring communities have the tools they need to prepare for and recover from disasters. Without strong federal leadership in flood risk management, communities along the Mississippi River could face even greater threats from worsening floods.
The report comes as local leaders in Vicksburg are already on high alert, with Mayor George Flaggs declaring a state of emergency last week ahead of potential incoming flooding. The riverfront city officials are currently coordinating with local and federal emergency management agencies, along with levee boards in neighboring states like Arkansas and Louisiana to ensure maximum preparedness.
The Mississippi River is not only a vital water source for over 50 cities but also supports diverse ecosystems and serves as a critical artery for economic activity. The river’s 30-million-acre floodplain provides habitat for nearly 900 species of fish and wildlife.
“Ensuring the health of the Mississippi River is essential for both wildlife and communities that rely on its waters,” Jessie Ritter with the National Wildlife Federation said as part of a press release from American Rivers. “The river supports diverse ecosystems, provides drinking water to millions, and serves as a critical artery for economic activity. We must unite together to ensure that the Mississippi River remains a source of life, prosperity, and inspiration now and for future generations to come.”
As climate change continues to drive more frequent and devastating floods, the combination of environmental challenges and policy rollbacks presents a dire situation for the Mississippi River. Conservationists and local officials alike stress the urgent need for coordinated federal support to safeguard this vital natural resource and the communities it sustains.
