Indus River Delta

"Originating high on the Tibetan Plateau, the Indus River flows more than 3,000km before emptying into the Arabian Sea. It is here where the fan-shaped delta forms an extensive system of swamps, mudflats, creeks, estuaries, marshes and mangroves forests. The Indus River Delta is an important region for migrating water birds, and is an area rich in fish, including giant snakehead," Indus baril, Indus garua, and Rita catfish. "It is also home to one of the few species of freshwater dolphin, the Indus river dolphin . . . Dams along the river reduce flows, particularly in lower parts of the Indus River, limiting the transport of much-needed fertile sediments downstream into the delta. They also fragment freshwater habitat, posing a serious threat to the survival of the river dolphin and other species. Water extraction for irrigation, runoff of chemicals into the river and introduced species also threaten the delta's freshwater species."
