Named after the second daughter of King Bhumibol, the Sirindhorn Dam was built in 1971. The reservoir it created is 27 miles (43 km) from north to south; the turbines produce 24,000 kilowatts of electricity. There is a park at the dam HQ, and a restaurant and bungalows. It is possible to walk out over the dam and to take a boat on the reservoir. Dams in Thailand have been funded by the World Bank since the 1950s to meet Thailand’s ever-increasing need for electricity. They are given support mainly by politicians and the business community. Residents and envir onmental groups have begun to campaign against the construction of new dams.
