About Khun Dan Prakan Chon Dam
Khun Dan Prakan Chon Dam is a large roller-compacted concrete dam in Hin Tang Subdistrict, Mueang Nakhon Nayok District, Nakhon Nayok Province, Thailand. Completed in 2004 as a royal initiative of King Bhumibol Adulyadej (Rama IX), it is among the world's longest RCC dams at 2,720 meters long. The dam impounds the Khlong Tha Dan River for irrigation, flood control and hydroelectricity, and is a major viewpoint and recreational reservoir surrounded by forested mountains.
