Bihar, Jharkhand to Sign MoU on Sone River Water Sharing
UPSC / SSC current affairs note · Polity
Why in news
Bihar and Jharkhand are set to sign a Memorandum of Understanding (MoU) to formalize the sharing of Sone river waters, ending a dispute that has persisted since Jharkhand's creation in 2000. The Union government is finalizing the signing date, with both states having completed internal approvals.
Background
The Sone river water sharing dispute arose after Jharkhand was carved out of Bihar in November 2000. The Bansagar Agreement of 1973, which allocated 7.75 million acre-feet (MAF) of Sone water to undivided Bihar, continued post-bifurcation but the division between the two successor states remained unresolved for nearly 25 years.
Key facts
Bihar and Jharkhand will sign an MoU to share Sone river waters, resolving a 25-year-old dispute.
The agreement divides the undivided Bihar's allocation under the 1973 Bansagar Agreement.
Bihar will receive 5.75 MAF and Jharkhand 2.0 MAF of Sone river water.
The allocation follows the unanimous recommendation of a Centre-constituted committee chaired by the Central Water Commission.
Jharkhand's cabinet approved the matter earlier in July 2026.
The Ministry of Jal Shakti issued an Office Memorandum on July 14, 2026, confirming both states' consent.
The signing is proposed for August 2026 in the presence of the Union Jal Shakti Minister and both chief ministers.
