The King Fahad Dam, previously known as Bisha Dam, is a gravity dam on Wadi Bisha about 35 km (22 mi) south of Bisha in the 'Asir Region of southwestern Saudi Arabia. The dam has many purposes , such as serving flood control, supplying water to nearby localities, irrigation and groundwater recharge. A water treatment plant was built in conjunction with the dam and it can supply up to 40,000 m3 (1,400,000 cu ft) of water to the city of Bisha a day. The dam was constructed between 1986 and 1997. It is named after King Fahad and is managed the Ministry of Water and Electricity. At 103 m (338 ft) in height, it was the tallest dam in the country until the 106 m (348 ft) Baysh Dam was completed in 2009. King Fahad's reservoir still has the largest storage capacity, at 325,000,000 m3 (263,000 acre⋅ft).[1]
