Telangana Chief Minister A. Revanth Reddy met Union Jal Shakti Minister C.R. Patil on 5 August 2026 and sought the Centre's help in resolving the Tummidihatti barrage height dispute with Maharashtra.
Telangana wants the proposed barrage on the Pranahita river raised from the agreed 148 metres to 150-152 metres.
The state argues that a 148-metre structure would not deliver sufficient water by gravity flow.
A Central Water and Power Research Station study found little difference in submergence between 148 metres and 152 metres, with about half the affected area lying within the river bed itself.
The barrage forms part of the Pranahita-Chevella scheme and is proposed at Tummidihetti village in Kouthala mandal of the erstwhile Adilabad district.
In an irrigation scheme, the height at which water is held decides whether it must be lifted or whether it will travel on its own. Water flows by gravity only if the source is above the command area it must reach, so raising a barrage by even a few metres can convert a project that needs continuous pumping into one that needs none — with an enormous difference in running cost and in the electricity the state must supply forever afterwards. That is Telangana's case for 150-152 metres. The reason the neighbouring state resists is symmetrical: the higher the water is held, the further upstream the reservoir spreads, and the submergence falls on Maharashtra's territory, villages and forest. Every barrage dispute between two states on a shared river reduces to this arithmetic — the benefit accrues downstream and the cost accrues upstream. This is why the submergence study matters so much here: if the additional area flooded by going to 152 metres lies mostly within the river bed, the upstream cost of the extra height is far smaller than it first appears.
Simple Analogy: Raising the barrage is like lifting one end of a water channel — a small lift at the source can make the whole length run by itself, but it also floods more of the ground behind you.
The Pranahita is formed by the meeting of the Wardha and Wainganga rivers and flows along the Telangana-Maharashtra boundary before joining the Godavari. The proposed barrage site at Tummidihetti lies in Kouthala mandal of the erstwhile Adilabad district in northern Telangana, close to that confluence. Because the river marks the state boundary along this reach, any structure raised on it puts the storage on one side and much of the submergence on the other, which is the structural reason the two states have to negotiate rather than decide unilaterally.
The Pranahita is among the largest tributaries feeding the Godavari, India's second longest river, which makes disputes on it consequential for the whole basin's allocation.
The statutory route for adjudicating such disagreements through a tribunal, which states usually try to avoid by negotiating bilaterally with Central facilitation, as Telangana is attempting here.
Water is in the State List, but inter-state rivers fall under Entry 56 of the Union List, which is what gives the Centre a role in convening these talks.
Telangana's insistence on extra height is fundamentally about avoiding lift irrigation costs, the same consideration that shapes several of the state's other Godavari projects.
