Bang Lang Dam

The Bang Lang Dam (Thai: , RTGS: Khuean Bang Lang, pronounced [kan bāŋ lāŋ]), also known as the Pattani Dam (, RTGS: Khuean Pattani, pronounced [kan pàt.tā.nī]), is a multi-purpose hydroelectric dam in the Bannang Sata District of Yala Province, Thailand. It was the first multi-purpose dam developed in Thailand's southern region. The dam impounds the Pattani River, creating the Bang Lang Reservoir. The dam and its accompanying power plant were developed as part of the Pattani Project.

Bang Lang Dam is an earth core rockfill dam. It is 430 m (1,410 ft) long and 85 m (279 ft) high. Its reservoir has a maximum storage capacity of 1,420,000,000 m3 (5.0×1010 ft3) with a catchment area of 2,080 km2 (800 mi2). The dam is considered multi-purpose supporting electricity generation, irrigation, flood control, fisheries and recreation activities.

The dam's power plant has three hydroelectric Francis turbine-generating units, each with an installed capacity of 24 MW. A nearby mini hydroelectric project at Ban Santi has a 1.275 MW generating unit and is also part of the Pattani Project. The combined annual power generation is 200 GWh.
