Third largest river in US Continental (Rio Grand River)

 Mexico, United States 

North America

Running 1,809 miles from its snow fed head 

Waters in the Colorado Rockies to the Gulf

Of Mexico,the Rio Grande. Known as the Rio

Bravo in Mexico, is the third longest river in 

the continental U.S . But it's also one of 

 America's most endangered rivers, 

Droughts, more than 30 large dams, and 

ever increasing water diversions for

agriculture and cities have left long stretches

of the river dry the recent years.  And in 

2001 the river failed to reach the Gulf Of 

Mexico for the first time ever.
