America's Ten Most Endangered Rivers, 2011 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.americanrivers.org.
