About America’s Most Endangered Rivers(TM)
For 26 years, American Rivers has sounded the alarm on 360 rivers through our America’s Most Endangered Rivers report.  The report is not a list of the “worst” or most polluted rivers, but is a call to action for rivers at a crossroads, whose fates will be determined in the coming year. Over the years, the report has helped spur many successes including the removal of outdated dams, the protection of rivers with Wild and Scenic designations, and the prevention of harmful development and pollution.
American Rivers’ staff and scientific advisors review nominations for the following criteria:
    •    A major decision that the public can help influence in the coming year
    •    The significance of the river to people and wildlife
    •    The magnitude of the threat, especially in light of climate change

For the third consecutive year, America's Most Endangered Rivers™ is sponsored by The Orvis Company, which donates 5% of their pre-tax profits annually to protect nature. ©2011 American Rivers
