Polavaram Project is a multi-purpose irrigation project which has been accorded national project status by the central government.〔(【引用サイトリンク】title= Indirasagar (Polavaram) Project, Ministry of water resources, GoI )〕 This dam across the Godavari River is under construction located in West Godavari District and East Godavari District in Andhra Pradesh state and its reservoir spreads in parts of Chhattisgarh and Odisha States also.〔(【引用サイトリンク】title= Agitation against Polavaram, SANDRP )〕 == Purpose == National River-Linking Project, which works under the aegis of the Indian Ministry of Water Resources, was designed to overcome the deficit in water in the country. As a part of this plan, surplus water from the Himalayan rivers is to be transferred to the peninsular rivers of India. This exercise, with a combined network of 30 river-links and a total length of at an estimated cost of US$120 billion (in 1999), would be the largest ever infrastructure project in the world. In this project's case, the Godavari river basin〔("Godavari river basin map" )〕 is considered as a surplus one, while the Krishna River basin is considered to be a deficit one. As of 2008, 644 tmcft of underutilised water from Godavari River flowed into the Bay of Bengal. Based on the estimated water requirements in 2025, the Study recommended that sizeable surplus water was to be transferred from the Godavari River basin to the Krishna River basin.〔 In July 1941, the first conceptual proposal for the project came from the erstwhile Madras Presidency. Later Diwan Bahadur L. Venkata Krishna Iyer, then chief engineer in the Presidency's irrigation department, made the first survey of the project site and made a definitive proposal for a reservoir at Polavaram. Sri Iyer not only visioned cultivation of over two crop seasons through this project, but also planned for a 40 megawatt hydroelectric plant within the project. The entire project was estimated to cost about . The old final designs〔Gujja, Biksham (2006). Perspectives on Polavaram, a major irrigation project on Godavari. Academic Foundation. pp. 17–19. ISBN 81-7188-578-0. http://books.google.co.in/books?id=HSnDO8Nlj2IC&lpg=PP1&dq=Perspectives%20on%20Polavaram%2C%20a%20major%20irrigation%20project%20on%20Godavari&pg=PP1#v=onepage&q&f=false.〕 of Polavaram dam was planned at full reservoir level (FRL) 208 ft MSL with 836 tmcft gross storage capacity and 150 MW hydroelectric plant. By 1946–47, the estimated cost rose to 1.29 billion. It was named the "Ramapada Sagar Project" since the backwaters of the reservoir would touch the Lord Rama temple at Bhadrachalam. In the old finalised project design by Dr. K.L. Rao, the right bank canal of Polavaram project was extended to south of Krishna River to serve irrigation needs in old Guntur district by envisaging aqueduct across the Krishna River.〔(【引用サイトリンク】title= Detailed report on Polavaram Project, GoAP )〕 The project presently under construction is scaled down to FRL 150 ft MSL. The project cost estimate in 2004 stood at 86.21 billion. In 1980, then Chief Minister of Andhra Pradesh T. Anjaiah laid the foundation stone for the project. However the project stayed idle until 2004 when the Y. S. Rajasekhara Reddy-led government came to power. In 2004, the Government of Andhra Pradesh sanctioned for the project. Soon after, tenders were issued for the commensurate worth of services for the right canal of the project. For the left canal, another 13.53 billion were sanctioned by the state government.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polavaram Project」の詳細全文を読む スポンサード リンク
