The Vorotan ( Armenian Որոտան , in scientific transliteration Orotan , Azerbaijani Bazarçay) is a river in the Transcaucasus .
The Worotan rises in the north of the Armenian province of Sjunik and initially flows 119 kilometers in a generally south-easterly direction through Armenian territory and then another 50 kilometers through the Nagorno-Karabakh republic , before it finally flows into the Hakari , a tributary of the Macaw . The provincial capital Sissian , the villages Aghitu and Vorotan , the monasteries Vorotnavank and Tatew as well as the Azerbaijani city of Qubadlı , which is controlled by Armenia, lie on its course. The Vorotan flows through mountainous terrain and in parts through deep gorges. During the Soviet era , three dams with hydroelectric power stations were built on the Vorotan .
In order to raise the water level in Lake Sevan , water from the Ketschut reservoir (between Gndevank and Jermuk ) has been fed into Lake Sevan through a 48.3 km long tunnel since the early 1990s . Since the amount of water supplied was not sufficient to raise the water level, the construction of a 21.6 km long tunnel from the Spandarjan reservoir on the Vorotan (near Sissian) to the Kechut reservoir was started in the 1980s. The construction work had to be stopped at short notice in 1988 after 18 kilometers were completed, because an armed conflict broke out between Armenia and Azerbaijan over the Nagorno-Karabakh region . At the end of the 1990s, construction began again. The Worotan-Arpa Tunnel was put into operation in 2004.
