Baia California, Mexico
The 100 m false-colour image of 25 March 2017 shows us the Colorado River Delta with surrounding desert. It is a region where the Colorado River flows into the Gulf of California (also known as the Sea of Cortez). Historically, the interaction of the river’s flow and the ocean’s tide created a dynamic environment, supporting freshwater, brackish, and saltwater species. Within the delta region, the river split into multiple braided channels and formed complex estuary and terrestrial ecosystems. Use of water upstream and the accompanying reduction of fresh water flow has resulted in loss of most of the wetlands of the area, as well as drastic changes to the aquatic ecosystems. However, a scheme is currently in place which aims to rejuvenate the wetlands by releasing a pulse of water down the river delta.
