Victoria Dam

Victoria Dam (Sinhala: වික්ටෝරියා වේල්ල Viktoriya Vella) is an arch dam located 130 mi (209 km) upstream of the Mahaweli River's mouth and 4 mi (6 km) from Teldeniya in Sri Lanka. It is named in honour of Queen Victoria of the United Kingdom. Its main purposes are irrigation and hydroelectric power production. It is the tallest dam in Sri Lanka, and supports a 210 MW power station, the largest hydroelectric power station in the country. Construction of the dam commenced in 1978, funded by aid granted by the United Kingdom under the patronage of Queen Elizabeth II, was completed during the presidency of Junius Richard Jayewardene, and was ceremonially opened by the prime minister of the United Kingdom, Margaret Thatcher.
