Bang Lang Dam

Bang Lang Dam is a large multipurpose dam on the Pattani River in Bannang Sata District, Yala Province, southern Thailand. Completed in 1981 by the Electricity Generating Authority of Thailand, it is the largest dam in southern Thailand. The dam provides hydroelectric power, irrigation and flood control, and forms a vast reservoir surrounded by forested mountains, making it a notable scenic and engineering landmark.

Visitors can expect a large concrete arch dam with a vast reservoir set among forested mountains. The site offers panoramic viewpoints over the reservoir and dam wall, a crest road, and landscaped areas for sightseeing and photography. The reservoir is used for boat trips to view the surrounding hills and shoreline. Facilities are basic and focused on scenic viewing rather than extensive recreation.

Constructed by the Electricity Generating Authority of Thailand (EGAT) between July 1976 and September 1981 as the first multipurpose dam in southern Thailand. The project was developed for hydroelectric power generation, irrigation, flood mitigation and water supply on the Pattani River. The dam is a concrete arch type, 85 meters high and 422 meters long, with an installed capacity of 72 MW.
