The Colorado River is the lifeline of the southwestern United States. The states of Arizona, Nevada and Colorado are very dry with little rain fall. Still, cities like Phoenix, Arizona and Las Vega, Nevada thrive in this part of the country. There are even farms in the southwest where crops like corn and lettuce are grown and sheep, cows and other animals are raised. The reason this area is able to thrive is because the Colorado River runs through it.
The river runs southwest from the Rocky Mountains of Colorado, through Utah and Arizona and into Mexico. It creates a border between Arizona and southeastern Nevada near Las Vegas. It also creates a border between Arizona and the southeastern part of California. The river empties into the Gulf of California, which is located in northwest Mexico. Smaller rivers and streams, which are known as tributaries, flow into the Colorado River and add to its power.
