Saving the Colorado River Delta, One Habitat at a Time

This image highlights the generally arid setting of the Colorada River delta estuary at its terminus and at low tide.
The Colorado River is the largest watershed in the southwestern US, emptying into the Salton Trough before reaching the Sea of Cortez. Over the past 2-3 million years, river sediments built a delta that extends from the US-Mexico border for a distance of 87 miles (140 km). However, today the Colorado River delta is undergoing significant erosion and diminishing in size due to the lack of sediment replenishment from upstream sources. Prior to impoundment of water from upstream dams the delta provided habitat for a wide variety of species including shrimp, corvina fish, and vaquita porpoise.
