Lam Takhong Dam

Lam Takhong Dam is an earthfill dam on the Lam Takhong River in Sikhio District, Nakhon Ratchasima Province, northeastern Thailand, about 60 km southwest of Nakhon Ratchasima city. Completed in 1974, it impounds a large reservoir used for irrigation, flood control, water supply and hydroelectric power, including a pumped-storage plant. The reservoir and surrounding hills offer scenic views and the dam is a popular stop along Mittraphap Road (Highway 2).

Visitors can expect a large reservoir set among low forested hills, an accessible earthfill dam crest with panoramic water views, and a designated viewpoint and rest area along Highway 2. The site includes landscaped picnic areas, parking, food stalls and photo spots overlooking the reservoir and the upper reservoir of the pumped-storage plant on the hilltop. The environment is open, windy and scenic, commonly visited as a short stop en route to Khao Yai.

Constructed between 1969 and 1974 by the Royal Irrigation Department as an earthfill dam on the Lam Takhong River for irrigation, flood control and water supply. Later developed for power generation with a conventional hydroelectric plant and Thailand's first pumped-storage power plant operated by the Electricity Generating Authority of Thailand (EGAT), with initial units commissioned in 1995 and expansion completed in 2002.

Provides irrigation water, domestic water supply and electricity for Nakhon Ratchasima Province and the northeastern region. The reservoir is a well-known local recreation area and landmark for travelers between Bangkok and Isan, and is often associated with scenic stops on the route to Khao Yai.
