The dam is situated between Pak Chona and Sikhiu districts in Nakhon Ratchasima province, Isaan.
The dam's purpose was to retain water for irrigation and water supply. After 2002 the stored water also serves as the reservoir for the Lam Takhong Pumped Storage Power Plant, the first plant one of this kind in Thailand.
Along the highway number 2 there are a few restaurants overlooking the dam. They offer typical Isaan food such as gai yang (BBQ chicken), somtam (papaya salad) and all sorts of fish.... of course served with khao nio (sticky rice).
