What Happened

Haryana and Rajasthan signed a Memorandum of Understanding (MoU) in New Delhi on June 29, 2026, to operationalise the 1994 Upper Yamuna River Board (UYRB) Agreement — a pact that had remained largely unimplemented for 32 years.
The signing was presided over by the Union Home Ministry, reflecting the Centre's role as facilitator in inter-state water disputes.
Under the new arrangement, Rajasthan will receive its allocated share of Yamuna water through an underground pipeline via the Western Yamuna Canal system during the monsoon season, targeting drought-prone districts such as Churu, Sikar, and Jhunjhunu.
A Rs 34,102 crore water project has been cleared to build the infrastructure necessary to deliver Rajasthan's share of the water from Hathinikund Barrage in Haryana.
The agreement resolves a long-standing dispute rooted in Rajasthan's claim that it was not receiving its due water allocation under the 1994 pact.

The 1994 Upper Yamuna River Board (UYRB) Agreement

The Memorandum of Understanding on sharing the surface flow of the Yamuna River was signed on May 12, 1994, among five riparian states and territories: Uttar Pradesh, Haryana, Rajasthan, Himachal Pradesh, and the National Capital Territory of Delhi. The agreement established the Upper Yamuna River Board (UYRB) — a statutory body under the Union government — to regulate the allocation and distribution of Yamuna waters among the basin states as per the agreed shares. Despite being in force for over three decades, implementation disputes, particularly regarding Rajasthan's share during lean-flow periods, kept the agreement largely non-functional.

Signed: May 12, 1994.
Parties: UP, Haryana, Rajasthan, Himachal Pradesh, NCT of Delhi.
Nodal body: Upper Yamuna River Board (UYRB), under the Union Ministry of Jal Shakti.
Mechanism: In surplus years, water distributed in proportion to allocations; in deficit years, Delhi's drinking water needs are met first, with the balance distributed proportionally among other states.
Key infrastructure: Hathinikund Barrage (Haryana) — the primary point of flow regulation on the upper Yamuna.

Connection to this news: The June 2026 MoU is not a new water-sharing agreement but an implementation pact to make the 32-year-old 1994 agreement operational, specifically for Rajasthan's water delivery through the Western Yamuna Canal system.

Inter-State Water Disputes: Constitutional and Statutory Framework

Water — specifically the "water, that is to say, water supplies, irrigation and canals, drainage and embankments, water storage and water power subject to the provisions of entry 56 of List I" — is a State subject under Entry 17 of the State List (Schedule VII) of the Indian Constitution. However, rivers flowing through multiple states (inter-state rivers) are governed at the Union level under Entry 56 of the Union List, which gives Parliament authority to regulate inter-state rivers in the public interest. Article 262 of the Constitution specifically deals with the adjudication of inter-state river water disputes, empowering Parliament to legislate for dispute resolution and, importantly, to exclude the jurisdiction of the Supreme Court from such disputes.

The Inter-State River Water Disputes Act, 1956 (IRWD Act), enacted under Article 262, is the primary statute. It provides for the constitution of a Tribunal by the Central Government when a dispute between states cannot be settled by negotiation. Tribunal awards are binding on all parties and carry the force of law once notified in the Official Gazette.

Constitutional provision: Article 262 — Parliament may legislate for adjudication of inter-state water disputes; may also bar Supreme Court/High Court jurisdiction.
State List Entry 17 (Schedule VII): water supply, irrigation, canals, drainage — state subject.
Union List Entry 56 (Schedule VII): regulation and development of inter-state rivers — Union subject.
Statute: Inter-State River Water Disputes Act, 1956 (amended 2002).
Tribunal mechanism: Central Government constitutes a tribunal (Chairman + 2 members, all Supreme Court judges) when negotiations fail.
Major water tribunals: Cauvery, Krishna, Godavari, Ravi-Beas, Mahadayi.

Connection to this news: The Haryana-Rajasthan dispute over the 1994 UYRB Agreement falls within this constitutional framework. The Centre's facilitation role (presiding over the MoU signing) reflects Union authority over inter-state rivers under Entry 56, without requiring a formal tribunal since both states reached agreement through negotiation.

Western Yamuna Canal System

The Western Yamuna Canal (WYC) is one of India's oldest irrigation canals, originating from Tajewala in Haryana (near Yamunanagar). Historically, it was developed during the Mughal period and substantially expanded under British administration. It serves as the primary surface water irrigation canal in Haryana and is the conduit through which Rajasthan's share of Yamuna water will now flow via a new underground pipeline. The canal draws water from the Hathinikund Barrage, which replaced the older Tajewala Headworks after 1999.

Western Yamuna Canal (WYC): originates at Hathinikund Barrage, Haryana.
Hathinikund Barrage: built 1999, replaced Tajewala Headworks; primary flow-regulation point on upper Yamuna.
Under the 2026 MoU: Rajasthan will receive water via an underground pipeline connected to the WYC during monsoon months when surplus water is available.
Target districts: Churu, Sikar, Jhunjhunu (arid/semi-arid areas with acute water scarcity).
Project cost: Rs 34,102 crore.

Connection to this news: The Rs 34,102 crore project will build the underground pipeline and related infrastructure to physically deliver Rajasthan's UYRB-allocated share through the Western Yamuna Canal network, converting a 32-year-old paper commitment into operational water supply.

Inter-state water disputes are among India's most persistent governance challenges, combining complex hydrology, conflicting agricultural and drinking water needs, and state political dynamics. The pattern of disputes — Cauvery (Karnataka vs. Tamil Nadu), Krishna (AP vs. Telangana vs. Maharashtra), Ravi-Beas (Punjab vs. Haryana vs. Rajasthan), Mahadayi (Goa vs. Karnataka vs. Maharashtra) — reveals structural issues: colonial-era agreements that did not anticipate post-independence state reorganisation, growing demand from agriculture (70% of India's freshwater use), and inadequate real-time monitoring of river flows.

India has 17 major inter-state river basins.
IRWD Act, 1956: only mechanism for formal adjudication — tribunals can take 10–30 years to resolve disputes.
Pendency: several tribunal awards remain unimplemented decades after issuance (e.g., Cauvery Water Disputes Tribunal, 1990 → Supreme Court final order 2018).
Jal Shakti Ministry: nodal ministry for water, created in 2019 by merging Ministry of Water Resources and Ministry of Drinking Water and Sanitation.

Connection to this news: The Haryana-Rajasthan MoU is notable as a rare case of inter-state water dispute resolution achieved through negotiation facilitated by the Centre — outside the formal tribunal mechanism — offering a potential model for other pending disputes.
