America's Ten Most Endangered Rivers,
2006
Each year the organization American Rivers analyzes the condition of
the nation's rivers to determine which are the most “endangered.”
Threats to these rivers include dams and channelizations that are
harmful to fish or wildlife populations; depletion due to the rivers'
use as a water supply for human populations; and coal mining operations
that fill streams with coal and dirt. For more information, refer to the
American Rivers website: www.amrivers.org .
