Hāmūn-e Gows Zerah
Gowd-e Zereh lies at the lowest end of the Sistan basin, amid the deserts south of the Helmand wetlands. In exceptionally wet years, overflow from the Hamun lakes reaches this shallow depression, where water collects without an outlet to the sea. Its brackish waters and surrounding salt flats change greatly with the supply from the rivers, leaving broad dry expanses when floods subside.
