of Bachawat tribunal dated 31 May 1976 is applicable for sharing the water available in the river among the riparian states. The Brijesh Kumar tribunal award given on 29 November 2013 is challenged by Andhra Pradesh in the Supreme Court and the case pending since then. The newly created state of Telangana also approached Supreme Court demanding a fresh tribunal hearing to secure its water needs on equitable basis. Even though the river does not flow through Tamil Nadu, the Telugu Ganga Project is a canal system that brings Krishna river water to that state's capital city of Chennai with the agreement of all basin states. Dams There are many dams constructed across the Krishna river. Dhom Dam Hippargi barrage Almatti Dam Narayanpur Dam Bhima Dam Jurala Dam Srisailam Dam Nagarjuna Sagar Dam Nagarjuna Sagar tail pond Pulichinthala Dam Prakasam Barrage Tungabhadra Dam Rajolibanda barrage Sunkesula barrage Hydroelectric power stations Krishna river is one of the rivers whose water energy is harnessed to a large extent by various hydro electric power stations in India. The following is the list of hydro electric power stations excluding small and medium installations. Mineral deposits Krishna river basin is endowed with rich mineral deposits such as oil & gas, coal, iron, limestone, dolomite, gold, granite, laterite, uranium, diamonds, etc. The following are the few noted deposits: Krishna Godavari Basin, oil & gas Yellandu, coal Bayyaram Mines, iron Kudremukh, iron Donimalai, iron Jaggayapeta mines, dolomite Nalgonda uranium deposits, Kollur Mine, diamonds Hatti Gold Mines, Pollution Most of the years, the river water is not joining the sea due to full utilisation of water mainly in agriculture. Closed river basin of Krishna means that the river ecosystem is on the verge of death. The river receives the waste from the large number of cities and the river basin population has increased to 80 million enhancing pollution load many folds into the river. Adequate average and minimum continuous environmental flows to the sea are not taking place in most of the years constricting salt export and leading to formation of saline and sodic alkaline soils in the lower reaches of the river basin. High alkalinity water is discharged from the ash dump areas of many coal fired power stations into the river which further increases the alkalinity of the river water whose water is naturally of high alkalinity since the river basin is draining vast area of
