TheLal Bahadur Shastri Dam is also known asAlmatti Dam is a hydroelectric project on theKrishna River[1] inNorth Karnataka, India which was completed in July 2005. The target annual electric output of the dam is 560 MU (or GWh).[2]
The Almatti Dam is the main reservoir of theUpper Krishna Irrigation Project; the 290MW power station is located on the right side of the Almatti Dam. The facility uses verticalKaplan turbines: five 55MW generators and one 15MW generator. Water is released in to theNarayanpur reservoir after using for power generation to serve the downstream irrigation needs. Two separate facilities namely, Almatti 1 Powerhouse and Almatti II Powerhouse each separated by distance do provide power generation capabilities.
During the initial stages of the project, estimated costs were projected as ₹ 1,470 crores, but following the transfer of project's management to theKarnataka Power Corporation Limited (KPCL), the estimated cost was reduced by over fifty percent to ₹ 674 crores. KPCL eventually completed the project at an even lower cost of ₹ 520 crores.[citation needed] The entire dam was finished in less than forty months, with construction ending in July 2005.The dam is located on the edge ofVijayapura andBagalkote districts. Geographically, it is located in the Vijayapura district,[3] but large areas of Bagalkote district have also been submerged due to filling of the reservoir. The dam holds a gross water storage capacity of 123.08TMC at 519 meters MSL.[3][4] The backwaters of the dam host several migratory birds during summer.[5]
The full reservoir level of Almatti dam was originally restricted to 160 feetMSL by thesupreme court of India. The Krishna River conflict betweenAndhra Pradesh,Karnataka, andMaharashtra was resolved by theBrijesh Kumar Tribunal and the dam was authorized to be raised to the height of 524 feet MSL with nearly 200 TMC gross storage capacity.[6]26 different radial spillway gates are housed in the Dam.
