Ratchburi Electricity Generating Holding Company said in a statement the dam, which it referred to as ‘Saddle Dam D’, was eight meters (26 feet) wide, 770 meters (2,526 feet) long and 16 meters (52 feet) high.
The dam “was fractured and the water had leaked to the downstream area and down to the Xe-Pian River which is about five kilometers from the dam,†said Kijja Sripatthangkura, chief executive officer of Ratchaburi Electricity Generating Holding Company.
International Rivers, a U.S.-based group that works to protect rivers and the rights of communities dependent on them, said the accident exposed “major risks†associated with some dam designs that cannot cope with extreme weather conditions.
