The Srisailam Dam is a dam constructed across the Krishna River at Srisailam in the Kurnool district in the state of Andhra Pradesh in India and is the 2nd largest capacity hydroelectric project in the country. The dam was constructed in a deep gorge in the Nallamala Hills, 300 m (980 ft) above sea level. It is 512 m (1,680 ft) long, 240.79 m (790.0 ft) high and has 12 radial crest gates. It has a huge reservoir of 800 km 2 (310 sq mi). The left bank hydroelectric power station generates 6 × 150 MW of power and right bank generates 7 × 110 MW of power. the dam also surrounded by thick forests and beautiful sceneries. The Srisailam project began in 1960, initially as a power project, across the Krishna, near Srisailam in Andhra Pradesh. After several delays, the main dam was finally completed twenty years later in 1981. In the meantime the project was converted into a multipurpose facility with a generating capacity of 770 MW by its second stage which was expected to be completed in 1987. The dam is to provide water for an estimated 2,000 km 2 (770 sq mi) with its catchment area of 206,040 km 2 (79,552 sq mi) and water spread of 1,595 km 2 (616 sq mi). Under the right branch canal 790 km 2 (310 sq mi) in Kurnool and Cuddapah districts will have assured irrigation. From the initial modest estimate of Rs.384.7 million for a power project the total cost of the multipurpose project was estimated to cross Rs.10 billion in its enlarged form. The 143 m (469 ft) high and 512 m (1,680 ft) wide dam has alone cost Rs.4.04 billion together with the installation of four generating sets of 110 MW each. The right branch canal is estimated to cost Rs.4.49 billion and the initial investment of Rs.1.4 billion has been provided by the World Bank. The projected cost-benefit ratio of the project has been worked out at 1:1.91 at 10% interest on capital outlay. On 2 October 2009, SriSailam dam experienced a record inflow which threatened the dam.
