At One Mississippi, we believe everyone deserves access to clean, safe water—and that starts with protecting the rivers, wetlands, and streams that sustain our communities. That’s why we’re speaking out against new efforts to roll back critical protections under the Clean Water Act. In a letter submitted to the Environmental Protection Agency (EPA) in April 2025, we urge decision-makers to uphold strong safeguards for wetlands and streams throughout the Mississippi River watershed. Weakening these protections would put drinking water for 20 million people in our watershed at risk, increase flooding and disaster costs, and threaten vital wildlife habitat. Read on to learn what’s at stake—and why the EPA must do more, not less, to protect clean water for all.

Additionally, our U.S. Army Corps consultant, Olivia Dorothy, provided oral testimony during an Environmental Protection Agency and Department of Army listening session on May 1st. Read the full oral testimony here.
