The Andijan Dam is a buttress dam on the Kara Darya River near Andijan in Andijan Province, Uzbekistan. Its reservoir covers 57.28 m (187.9 ft) and stretches into neighboring Osh Province, Kyrgyzstan. The dam serves several purposes to include irrigation in the Fergana Valley and hydroelectric power production. Water released from the dam can enter a canal on either side of the river downstream. The dam has two power stations located at its base, Andijan 1 and Andijan 2. The former contains four 35 MW turbine-generators and the latter contains two 25 MW Francis turbine-generators for a total installed capacity of 190 MW. Construction on the dam began in 1969 and the generators in Andijan 1 were commissioned between 1974 and 1984.^[1] Construction on Andijan 2 began in 2007 and it was commissioned on 2 September 2010. It cost US$28.5 million of which US$15.93 million was supplied by the Exim Bank of China.^[2]
