The Colorado River has been named America's Most Endangered River seven times.
America's Most Endangered Rivers is a list of threatened rivers in the United States compiled by the nonprofit group American Rivers. First published in 1984, the annual list spotlights ten threatened rivers–rivers that are facing environmental degradation due to existing or proposed development projects. The list is intended to build public awareness and spur action toward addressing specific environmental issues.[1][2]
Most-listed rivers
A number of rivers have been listed on America's Most Endangered Rivers multiple times, either in whole or in part. This list includes items that have appeared three or more times.
American Rivers announced its ten most endangered rivers of 1987 via press release, with no accompanying report. All ten rivers faced dam proposals. The rivers were not ranked.[54]
