The Colorado River feeds us and powers our lives, irrigating millions of acres of farmland and generating billions of kilowatt-hours in hydroelectric power. Forty million people get drinking water from the Colorado River. Cities from Denver to Los Angeles couldn’t exist without it. It supports 30 Tribal Nations.

But we’re using more water than the river has to give. The Colorado River has already lost trillions of gallons to rising temperatures over the last two decades. Meanwhile, rampant growth and water-intensive farming have depleted groundwater supplies. This means Western states must fundamentally rethink how water is divided up and used. In the latest season of “How We Survive,” we unpack the water crisis in the American West and investigate the solutions that could help us survive.
