Some Of America's Largest And Most Important Rivers Are In Crisis

The nation's most endangered river is the Colorado River.

America's rivers connect the country, providing most Americans and businesses with a supply of fresh water.

"Unfortunately our rivers are facing a significant crisis," said Tom Kiernan, president of the American Rivers environmental group.

American Rivers unveiled its annual list of the most endangered rivers, and the trouble spans the entire country. Rivers from coast to coast and border to border are endangered.
