Lake Charvak (from Chor bogh, four gardens in Persian) (also transliterated as Tcharvak) Uzbek: Chorvoq is a water reservoir in the northern part of Tashkent Province, Uzbekistan. The reservoir was created by erecting a 168 m (551 ft) high stone dam (Charvak Hydropower Station) on the Chirchiq River, a short distance downstream from the confluence of Pskem, Ko'ksu and Chatkal rivers in the western Tian-Shan mountains, which provide the main volume of water. Currently the confuence cannot be seen and all three rivers discharge directly into Charvak.
