Temenggor Dam is now the third largest dam in Malaya. It was once the largest dam and largest hydroelectric generation facility upon completion in 1979, before being overtaken by the Kenyir Dam in 1985. It holds a special place in the history of Malaysia for its military role in flooding the Upper Perak River and cutting off the communist terrorists' infiltration route from the Betong salient in Thailand.
