The Lam Takhong Dam is an embankment dam on the Lam Takhong River between Pak Chong District and Sikhio District in Nakhon Ratchasima Province. The dam was originally constructed in 1974 for the purposes of irrigation and water supply but after 2002, its water storage also serves as the lower reservoir for the Lam Takhong pumped storage power plant, Thailand's first power plant of that type.
Lam Takhong is also a water reservoir with a total capacity of 310×106 m3 (251,321 acre⋅ft) and has become an attraction in its own rite. Stunning views of the reservoir can be had from the Mittraphap Highway and there are various options to stop along the reservoir and dam.
