Tungabhadra Dam is across the river Tungabhadra, a tributary of River Krishna. The dam is near the town of Hosapete in Karnataka. It is considered a multipurpose dam. Its storage capacity is 135 Tmcft. Owing to siltation, the capacity has come down by about 30 tmcft. If there are seasonal and late rains, the dam releases an estimated 235 tmcft. It is filled when water is let into the canals during the rainy season. The main architect of the dam was Thirumalai Iyengar, an engineer from Madras; a general-purpose hall was named after him. (Multipurpose dams help in generation of electricity, irrigation of land, prevention and control of floods, etc.) It has become a picnic or tourist spot over the years. Tungabhadra Dam is near heritage site Hampi. One of the major problems and concerns associated with TB Dam is it has been undergoing lot of silting. Because of silt deposition in the dam, the storage capacity of the dam is coming down. Another major problem associated with TB Dam is increased pollution, resulting in decreasing fish population. This is seriously affecting fishermen, who are solely dependent on the river for their livelihood.
