The Sumbar (also Sari-su, Sara-su and Ṣáríṣú) is a fast flowing river in southern Turkmenistan and northern Iran. It a tributary of the Atrek. The name Sari-su means yellow water in Turkic languages, but is applied to a number of other rivers as well. It used to be an area for Caspian tigers[1] in Turkmenistan, until the last individual was killed in January 1954.
The Sumbar is 245km (152miles) long and drains a basin of 8300km2. It arises in the Kopet Dag mountains in Iran and flows into Turkmenistan. For a long stretch before the Sumbar runs into the Atrek, it is separated from the latter by a range of hills called the Marábeh.[2] The Atrek becomes part of the Turkmenistan-Iran border where the Sumbar flows into it, at 37.9911°N 55.2747°W.
