Lake Qaraoun (Arabic: بحيرة القرعون‎‎ / ALA-LC: Buḥayrat al-Qara‘ūn) is an artificial lake or reservoir located in the southern region of the Beqaa Valley, Lebanon. It was created near Qaraoun village in 1959 by building a 61-metre-high (200 ft) concrete-faced rockfill dam (the largest dam in Lebanon) in the middle reaches of the Litani River (longest river in Lebanon). The reservoir has been used for hydropower generation (190 megawatts or 250,000 horsepower), domestic water supply, and for irrigation of 27,500 hectares (68,000 acres).
