Vajiralongkorn Dam, formerly named the Khao Laem Dam, is a concrete-face rock-fill dam (CFRD) in Thong Pha Phum district in Kanchanaburi, Thailand. The dam lies across the Khwae Noi River (River Kwai) and was renamed Vajiralongkorn Dam after Crown Prince Maha Vajiralongkorn on July 13, 2001. Vajiralongkorn Dam is Thailand's first CFRD and supplies a 300 MW hydroelectric power station with water.
Dam construction began in 1979 and took five years to complete. Its reservoir started filling with water in June, 1984. Three 100MW hydropower generators came on line in October and December, 1984 and February 1985 respectively. The reservoir created by the dam has a maximum storage capacity of 8,860 million cubic meters covering a total catchment area of 3,720 square kilometers. Average runoff into the reservoir is approximately 5,500 million cubic meters per year.
