Across the U.S.-Mexico border, the Colorado River once flowed freely into the ocean. When the freshwater and saltwater met, it created an explosion of life in the desert. But most of that lushness dried up when people used up the river. We meet people who have worked for decades to restore parts of the delta's lost wetlands. They created a historic agreement between the two countries that designates some river water for the environment. That means that sometimes, this dry delta flows with water again, and occasionally, the river meets the ocean. The final installment in our 10-part series.
