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 Iran–Turkey border, not far from Mount Ararat and flows south and east into the Araxes at the town of Pol Dasht.
A major tributary of the Zangmar is the Barun River which is dammed at some above Maku, forming the Maku-Barun reservoir. The dam is rammed earth and riprap with a clay lining high, impounding some of water.
After leaving Maku, the river flows past Tappeh Bashi-ye Namaz, and Moradluy-e Olya before entering the Araxes.
