Pak Mun Dam

The Pak Mun Dam (Thai: เขื่อนปากมูล) is a gravity dam located 5.5 km west of the confluence of the Mun and Mekong rivers in Ubon Ratchathani province, Thailand. It was constructed by the Electricity Generating Authority of Thailand (EGAT) with support from the World Bank at a total cost of US$240 million, and completed in 1994.

The project has been criticized for adverse effects on the fisheries of the Mun River, insufficient compensation payments to affected villagers, and failure to produce the projected power output. The immediate impact of the dam was to flood 117 square kilometres of land and displace around 3,000 families. In all around 25,000 villagers claim to have been affected by the dam. Protests have been staged at the dam site and outside Government House in Bangkok. EGAT has paid out US$44.24 million in relocation compensation, plus US$15.8 million for loss of fisheries.
