America’s Most Endangered Rivers® 2027 Nomination Process

Rivers make life possible. They provide our drinking water, nourish ecosystems, sustain local economies, and connect communities across the country. But America’s rivers are losing their life-giving power. This is not just an environmental tragedy, but a profound threat to our health, communities, and safety.
For this reason, every year, American Rivers announces America’s Most Endangered Rivers® — the campaign that shines a national spotlight on rivers at risk, galvanizes the public to take action, and helps secure lasting victories for clean water and healthy rivers.
Since 1984, local leaders have teamed up with American Rivers to use the report to save their local rivers, consistently scoring decisions that benefit rivers and communities. If your river facing an urgent threat, with a decision in the coming year that will impact its fate, please consider nominating your river for the 2027 report.
DATES AND DEADLINES
- All nominations must be received by Thursday, October 1, 2026.
- Nominators will be informed of the selection decision by February 2027.
- American Rivers will release the report on Tuesday, April 13, 2027, in a comprehensive communications and public engagement campaign coordinated with the nominating partners.
SELECTION CRITERIA
We will select rivers based on the following criteria:
- The significance of the river to people, wildlife, and nature.
- The magnitude of the threat to the river and its communities.
- The presence of an upcoming (June 2027 to February 2028) local, state, or federal policy decision that will impact the river’s fate. (This is the most important selection criterion. If there is no near-term decision point, please do not nominate the river.)

America’s Most Endangered Rivers® partner testimonials
The designation of the Tijuana River as one of the country’s most endangered by American Rivers has generation a national recognition for the plight of this ecological and cultural jewel of the US-Mexico border region. For far too long, the pollution crisis in the Tijuana River has been ignored and American Rivers has helped us elevate the issue to where it needs to be heard the most.
Zach Plopper, Sr. Environmental Director, Surfrider Foundation
The Most Endangered Rivers designation strengthened and amplified a message: That the health of our river matters,, not just to us, but to other environmentalists across the nation and for that we are forever grateful for the bittersweet designation.
Mario Ordonez-Calderon, Un Mar de Colores
The process went well and I commend American Rivers on the MER program and everything that they do.
Charles Pfeifer, Jackson Audubon, Orleans Audubon, and Louisiana Wildlife Federation
MER listings make a difference and immediately shine the public spotlight on an issue. The exposure catapults a campaign into the limelight and makes decision-makers pay attention. American Rivers was superb in supporting as a partner and making sure assets were in place… Love working with can-do, action-oriented optimists. Great experience!
Karen Knudsen, Clark Fork Coalition
I appreciate how American Rivers listens to, focuses on, and uplifts the local actors.
Alicia Hamann, Friends of the Eel River
