The Ubol Ratana Dam (pronounced: Ubon Rat), formerly known as the "Phong Neeb Dam", is a multi-purpose dam in tambon Khok Sung, Ubolratana district, approximately 50 km (31 mi) north of Khon Kaen, Khon Kaen province, Thailand. It was the first hydroelectric power project developed in Thailand's northeastern area of Isan.[1] The dam impounds the Nam Phong, which flows into the Chi River and thence to the Mun River, a tributary of the Mekong River. The dam was given its current name by royal permission in 1966, in honour of princess Ubol Ratana, the eldest child of King Bhumibol Adulyadej.
