Deciding About the Colorado River Delta takes a look at what is arguably one of the biggest environmental issues in the Colorado River Basin: the Mexican delta. Home to hundreds of species of birds and numerous endangered species, the Delta has become a point of interest because of its valuable wetland and estuary habitat. However, since the damming of the Colorado River, water that used to flow into the Delta no longer does except in very wet years. Environmentalists have been pushing for the U.S. to increase flood flows to Mexico in order to support the habitat.
