Is your river facing a decision in the coming year that will impact its fate? America’s Most Endangered Rivers® is the most influential national campaign to galvanize public action and secure victories for rivers, clean water and communities. Every year, American Rivers, an environmental non-profit, generates a report and media blast on 10 rivers at a crossroads where an upcoming action could make or break the future health of the river. We are now accepting nominations for our 2021 report from interested groups throughout the United States. 

We have been working hard this year to continue to spread the word about threats facing our nation’s rivers throughout the year, and the response has been great. If you didn’t get to see our 2020 report, please go to:  

To nominate a river, please complete the MER 2021 Nomination Form to be found here:

Due Date:  Friday, November 13, 2020

The 10 rivers selected as America’s Most Endangered Rivers® of 2021 will be spotlighted in a report in April 2021 that receives national media and advocacy. Partners will also receive comprehensive communications, outreach and advocacy partnership from American Rivers to motivate real change for rivers at risk.

Your river is eligible if it meets the following primary criteria:

•    The public can influence a decision in the coming year that will impact the river’s fate

•    The river holds deep meaning to people and nature

•    The magnitude of threat to the river and its communities is significant, especially in light of a changing climate and/or environmental justice

American Rivers would especially like to highlight rivers where there are river-related threats that impact equality and justice. We hope that if you know of such a place where a decision on a river issue could impact a marginalized community, that you consider submitting a nomination.
