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.

A major tributary of the Zangmar is the Barun River which is dammed at 39°11′17″N 44°28′55″E some 12 miles (19 km) above Maku, forming the Maku-Barun reservoir. The dam is rammed earth and riprap with a clay lining 78 metres (256 ft) high, impounding some 135,000,000 cubic metres (109,000 acre⋅ft) of water.[1]

After leaving Maku, the river flows past Tappeh Bashi-ye Namaz, and Moradluy-e Olya before entering the Araxes at 39°21′08″N 45°05′07″E.
