Atrek River

The Atrek River is a prominent waterway in Western Asia, originating in northeastern Iran and flowing for approximately 669 kilometers into the Caspian Sea. It holds the distinction of being the only river to reach the Caspian Sea from Turkmen territory, with its lower course serving as the natural border between Iran and Turkmenistan. The river's flow is marked by extreme variability, primarily due to heavy extraction for irrigation and inconsistent precipitation in the Kopet Dag mountains. In dry years, the Atrek often fails to reach the sea coast as its entire volume is diverted into irrigation canals for agriculture. Geographically, the river is divided into the mountainous upper course in Iran and the flat lower course in the Turkmen lowlands. The delta region is a critical stopover for migratory birds and supports unique flora adapted to the saline soils of the coastal environment.
