A primary consideration in developing the list each year is American River's determination whether there is a major decision regarding a selected waterway that the public can help influence in the coming year. In announcing this year's listing, American Rivers noted that the report annually highlights "urgent threats to rivers and has spurred the public to take action. Through the report, we have helped sound the alarm on hundreds of rivers, saving them from threats like pollution and new dams."
