Vajiralongkorn Dam

Vajiralongkorn Dam, formerly Khao Laem Dam, is a rockfill dam on the Khwae Noi River in Nong Lu, Sangkhla Buri District, Kanchanaburi Province, western Thailand. Operated by the Electricity Generating Authority of Thailand (EGAT), it was constructed between 1979 and 1984 for hydroelectric power generation, irrigation and flood control. The dam creates a large reservoir surrounded by forested mountains and is a notable viewpoint and engineering attraction near the Myanmar border.

Visitors can expect a large rockfill dam with a concrete-faced embankment, a wide reservoir extending north toward Sangkhla Buri, and panoramic viewpoints from the dam crest and designated overlooks. The site includes an EGAT visitor area, exhibition displays about power generation, and open paved areas for sightseeing and photography. The surrounding landscape is mountainous and forested, with calm reservoir waters used for boating and scenic views, especially at sunrise and sunset.

Construction began in 1979 and was completed in 1984 as Khao Laem Dam, a rockfill dam with concrete facing on the Khwae Noi River for hydroelectric power, irrigation and flood control. It was later renamed Vajiralongkorn Dam in 2001. The project is managed by the Electricity Generating Authority of Thailand and was one of the major hydroelectric developments in western Thailand.
