This story is part of a special National Geographic News series on global water issues.
The Colorado River is one of the most used and contested waterways on Earth. It provides water for 30 million people, and has many dams and diversions along its 1,450 miles (2,333 kilometers).
Because it is so heavily tapped for agriculture, industry, and municipal uses along its course, the Colorado River rarely reaches its delta and the Gulf of California. About one-tenth of the river's former flow now makes it to Mexico, but most of that is used for farming and cities south of the border.
