Zangmar River

The Zangmar River (also known as the Ṭłmut River) is a river in Maku County, West Azarbaijan Province, Iran. It originates in the Zagros Mountains above Maku, Iran along the Turkish-Iranian border, not far from Mount Ararat and flows south and east into the Araxes at the town of Pol Dasht.
