Hyderabad Nagarjuna Sagar Water Releases Renew State Tensions
A fresh dispute over Krishna river water erupted at Nagarjuna Sagar on Wednesday after Andhra Pradesh and Telangana released water through their respective powerhouses, each questioning the other’s actions. The confrontation highlights how unresolved allocation issues continue to complicate reservoir operations and water security across the two states as the 2026–27 water year gets underway.
The latest episode began when Andhra Pradesh released around 2,000 cusecs through its powerhouse into the right main canal. Telangana subsequently released a similar quantity through its left-bank powerhouse, citing drinking water requirements. Both states brought the development to the attention of the Krishna River Management Board (KRMB). Telangana officials alleged that Andhra Pradesh started power generation without prior permission from the KRMB or information to the state administration. At the time, the reservoir level was reported at about 535.5 feet. The dispute comes soon after the states failed to settle their competing requirements at a KRMB committee meeting on Krishna water sharing. For the current water year, Telangana has sought 112 thousand million cubic feet (tmcft), while Andhra Pradesh has sought 47 tmcft through October, primarily citing drinking water needs.
The disagreement reflects a larger challenge facing the Krishna basin: water requirements are increasingly being negotiated against uncertain availability, competing urban and agricultural demands and the operational needs of reservoirs and hydropower projects. Nagarjuna Sagar is particularly sensitive because releases through its powerhouses can simultaneously serve electricity generation and downstream water requirements. Decisions taken at the reservoir can therefore have consequences beyond the immediate canal system, affecting irrigation planning, drinking water supplies and power operations. The two states have faced repeated confrontations over the management of shared Krishna projects. Tensions at Nagarjuna Sagar escalated sharply in late 2023, when a dispute over operational control prompted the deployment of central security forces. Subsequent arrangements established clearer operational jurisdictions for the respective portions of the dam.
The recurring disagreements point to the limitations of ad-hoc decisions during periods of water stress. Water managers and policy experts have increasingly emphasised transparent accounting, real-time reservoir data and clearly defined operating protocols as essential for reducing conflict between basin states. For cities and rural communities dependent on Krishna supplies, the issue is ultimately less about administrative control and more about reliability. Drinking water systems, farming operations and power planning all require predictable releases, particularly during years when inflows are difficult to forecast. The immediate standoff will now depend on discussions through the KRMB and the respective state administrations. A durable solution will require the two states to follow agreed operating procedures while building a more transparent framework for allocating and monitoring a resource under growing climatic and demand pressures.
