         To commemorate the 5th cycle Birthday Anniversary of His Majesty King Bhumibol Adulyadej, the project on the construction of Chiew Lan for the purpose of irrigation and power generation was incorporated in the 4th National Economic and Social Development Plan (1977-1981).
         The construction of Chiew Lan Dam commenced on February 9, 1982 and was completed in September 1987. His Majesty King Bhumibol Adulyadej graciously gave the name “Rajjaprabha” meaning “the Light of the Kingdom” to the dam. The dam and the hydropower plant were inaugurated by His Majesty King Bhumibol Adulyadej accompanied by Her Royal Highness Princess Maha Chakri Sirindhorn on September 30, 1987.
