Lake Charvak (Uzbek: Chorvoq; from Chor bogh, "four gardens" in Persian) 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.
