The mighty 1,540-mile-long Colorado River provides water for over 40 million people in the Southwestern U.S. and is a vital lifeline for people in seven states and Mexico. It has a drainage basin of over 246,000 square miles and it provides water to the cities of Los Angeles, Las Vegas, Phoenix, Denver, and many more. However, it has been drying up over the 21st century, threatening millions of Americans’ access to freshwater.
