Bihar and Jharkhand on Monday, August 31, signed a Memorandum of Understanding (MoU) in New Delhi to settle their nearly 25-year-old dispute over the sharing of Sone River water. The agreement covers the distribution of 7.75 million acre-feet (MAF) of water originally allocated to undivided Bihar under the 1973 Bansagar Agreement, with 5.75 MAF going to Bihar and 2 MAF to Jharkhand.
The signing took place in the presence of Union Home Minister Amit Shah, Union Jal Shakti Minister C.R. Patil, Bihar Chief Minister Samrat Choudhary, Jharkhand Chief Minister Hemant Soren, Bihar Deputy Chief Minister Vijay Kumar Choudhary, Union Home Secretary Govind Mohan and senior officials from both states and the Centre. Shah said the pact would improve access to irrigation and drinking water across large parts of the two states and directly benefit lakhs of farmers.
He described the settlement as an example of cooperative federalism, saying long-standing disputes can be resolved when states work together through dialogue and consensus. Bihar and Jharkhand welcomed the agreement, which is also expected to clear the way for long-pending water infrastructure projects, including the Indrapuri Reservoir Project.
Water Shares Settled
The agreement settles a complicated question that emerged after Jharkhand was carved out of Bihar in November 2000. Under the 1973 Bansagar Agreement, undivided Bihar had been allocated 7.75 MAF of Sone River water. After bifurcation, however, Jharkhand sought a formal share of that allocation, leading to a prolonged disagreement over how the water should be divided between the two states.
Under the new arrangement, Bihar will receive 5.75 MAF, while Jharkhand will receive 2 MAF as its share. The settlement is expected to benefit several districts that depend heavily on the Sone River and its irrigation network. In Bihar, these include Bhojpur, Buxar, Rohtas, Kaimur, Aurangabad, Arwal, Gaya and Patna. In Jharkhand, Palamu, Garhwa and other areas are expected to gain improved access to water for irrigation and drinking purposes.
Bihar Deputy Chief Minister and Water Resources Minister Vijay Kumar Choudhary described the settlement as being in the interests of both states, saying the removal of the deadlock would allow them to move ahead with irrigation and flood-management requirements.
Dispute’s Long Background
The disagreement was closely linked to the fate of the proposed Indrapuri Reservoir Project in Bihar. Following the creation of Jharkhand, the state sought recognition of its share of the Sone River water and did not give its consent to the reservoir project in the absence of an agreed allocation. The issue remained unresolved for years despite discussions involving the Centre, Bihar and Jharkhand.
In January 2026, the Bihar Cabinet approved a draft water-sharing agreement under which Jharkhand would receive 2 MAF from the 7.75 MAF allocation of undivided Bihar. The move was expected to pave the way for the Indrapuri project and strengthen irrigation facilities across several districts. The latest agreement now formally establishes the allocation between the two states.
Shah said the settlement had “permanently resolved” the nearly 25-year-old dispute and highlighted it as the fourth inter-state water-sharing agreement reached this year through efforts to resolve long-pending issues through dialogue and consensus. Bihar CM Samrat Choudhary and Jharkhand CM Hemant Soren also expressed gratitude to Prime Minister Narendra Modi and Shah for facilitating the agreement.
The Logical Indian’s Perspective
Water is not merely a political or administrative resource; for millions of people, it determines whether crops can be cultivated, whether families have reliable drinking water and whether rural communities can plan for the future with greater security. The Bihar-Jharkhand dispute lasted for almost a quarter of a century, but its resolution demonstrates why dialogue, negotiation and a willingness to accommodate competing needs matter in a federal democracy.
The agreement does not erase the complexity of managing a shared river, but it offers a constructive example of states moving from disagreement towards cooperation. As climate pressures, growing populations and competing demands place greater stress on water resources, such cooperation will become increasingly important. Rather than allowing shared resources to become permanent sources of conflict, governments can work towards arrangements that recognise the needs and dignity of people on both sides of a boundary.
Do you think more long-pending inter-state disputes can be resolved through dialogue and cooperative federalism in a similar way?
