Structure of Tunga Bhadra Dam
Tunga Bhadra Dam's chief architect was Dr. Thirumalai Iyengar. Since the dam was built as per his plans, a general purpose hall at this place was made in his honour. The storage capacity of the dam is 135 Tmcft. Due to siltation, the capacity of this dam is decreased to 30 Tmcft. In case of late and seasonal rains, 235 Tmcft water, reserved in the dam, is distributed.
Of the three canals included in the Tungabhadra project, the Left Bank Canal is 225 kilometers in length with a capacity of 7000 cusecs cubic feet per second. It has the potential to provide irrigation to about 3 lakh hectares of land in the Raichur and Bellary district in the state of Karnataka and Kurnool, Cuddapah and Anantpur district in the state of Andhra Pradesh.
The Low Level Canal is 349 kilometers in length. Originating from the right bank of the Tungabhadra River, this canal runs through the states of Andhra Pradesh and Karnataka.
