Lake Charvak (Uzbek: Chorvoq; from چهارباغ Char bagh, "four gardens" in Persian) is a water reservoir in Boʻstonliq District in the northern part of Tashkent Region, Uzbekistan, separating Ugam (north), Pskem (east), and Chatkal (south) ranges.

The reservoir was created by erecting a 168 m (551 ft) high stone dam (Charvak Hydropower Station) on the river Chirchiq, a short distance downstream from the confluence of Pskem, Koʻksuv and Chatkal rivers in the western Tian Shan mountains, which provide the main volume of water.

These sites were investigated by the Institute of History and Archaeology of Uzbekistan before the dam was constructed.

[2] Lake Charvak is a popular resort in Tashkent region and thousands of holiday makers from all over Uzbekistan and neighbouring countries visit the reservoir.

Villages on the banks of Charvak such as Yusufhona, Burchmullo, Nanay, Chorvoq, Sidjak, Bogʻiston, and their surroundings offer wide range of hotels, dachas, houses and tapchans to accommodate tourists.
