Chhattisgarh CM says Mahanadi water dispute with Odisha will end soon

Chhattisgarh's Chief Minister says the Mahanadi water dispute with Odisha will be settled very soon. He says both States have agreed to accept whatever the Central Water Commission decides. The core issue, pending before a tribunal since 2018, is how much water reaches Odisha in the dry months.

  1. Context1 / 5
    • Chhattisgarh Chief Minister Vishnu Deo Sai began a two-day visit to Odisha on 20 September 2026.
    • He met Odisha Chief Minister Mohan Charan Majhi at Majhi's residence in Bhubaneswar.
    • Sai said the Mahanadi water dispute between the two States will be resolved very soon.
    • He said both States have told the Centre they will accept the Central Water Commission's decision on the matter.
  2. Key highlights2 / 5

    Odisha's complaint: Odisha says Chhattisgarh blocked the river's natural flow by building barrages and weirs upstream to supply water to industries.

    Dry-season flow: Odisha says these projects cut the water reaching the Hirakud Reservoir and downstream areas in the non-monsoon months.

    Tribunal still active: The Centre set up the Mahanadi Water Disputes Tribunal on 12 March 2018. Its next hearing is on 28 September.

    Earlier talks: The two Chief Ministers met in New Delhi on 30 July, with Union Water Resources Minister C.R. Patil present. Majhi then said he expected a settlement before Diwali.

    Technical talks: Technical teams from both States were due to meet again on 21 September.

    Sai's reasoning: Sai linked the expected settlement to the BJP governing both States and the Centre. This is his assessment, not an agreed outcome.

  3. Key concepts3 / 5
    1. Inter-State river water disputes — Article 262
    • Article 262 lets Parliament make a law to settle disputes over rivers that flow through more than one State.
    • Under it, Parliament passed the Inter-State River Water Disputes Act, 1956. The Act lets the Centre set up a tribunal when a State complains and talks fail.
    • Article 262(2) lets Parliament stop courts, including the Supreme Court, from hearing such disputes. The 1956 Act does this for disputes sent to a tribunal.
    • A 2002 amendment gave a tribunal's final award the same force as a Supreme Court order.
    • Distinction: A tribunal decides the dispute under law. A negotiated deal depends on both States agreeing.

    News connection: The Mahanadi tribunal is still hearing the case, even as the two States try to settle it through talks.

    1. Central Water Commission (CWC)
    • The CWC is India's top technical body on water resources. It works under the Ministry of Jal Shakti.
    • It collects river flow data, examines irrigation and dam projects, and advises States on water planning.
    • It is not a court. Its role here rests only on both States agreeing to accept its view.

    News connection: Sai says both States have handed the CWC the job of settling the dispute through dialogue.

    1. The Mahanadi basin and the upstream–downstream problem
    • The Mahanadi rises near Sihawa in Chhattisgarh's Dhamtari district. It flows east through Odisha into the Bay of Bengal.
    • Main tributaries include the Seonath, Hasdeo, Mand and Ib on the left bank, and the Ong and Tel on the right.
    • The Hirakud Dam near Sambalpur, Odisha, stores the river's water for irrigation, power and flood control.
    • Upstream versus downstream: The upstream State controls how much water flows on. The downstream State bears any shortfall. The monsoon hides this gap. The dry months expose it.

    News connection: Odisha, the downstream State, says Chhattisgarh's upstream barrages reduce its dry-season share.

  4. Way forward4 / 5

    Share one set of data: Make basin-wide flow data public, so both States argue from the same numbers.

    Protect environmental flow: Keep a minimum flow in the river all year. Environmental flow is the water a river needs to sustain its fish, wetlands and delta.

    Make any deal binding: Record the settlement formally, for example before the tribunal, so it survives a change of government in either State.

    Which one of the following is not a feature to Indian federalism?

    1. There is an independent judiciary in India.
    2. Powers have been clearly divided between the Centre and the States.
    3. The federating units have been given unequal representation in the Rajya Sabha.
    4. It is the result of an agreement among the federating units.
    Show answer

    Answer: D. VERDICT: The answer is that it is the result of an agreement among the federating units. Indian federalism did not arise from such an agreement. ANALYSIS: The Constitution establishes a federal system with two governments, a division of powers, a written and supreme Constitution, an independent judiciary and bicameralism, so the first three options all describe genuine features. Article 1 describes India as a Union of States, and the framers chose that phrase deliberately to convey two things: the Indian federation is not the result of an agreement among the States, and no State has the right to secede from it. The fourth option therefore states precisely what Indian federalism is not. SOURCE: M. Laxmikanth, Indian Polity, chapter on salient features of the Constitution. Source type EM. HOW TO CRACK IT: The phrase Union of States in Article 1 is doing constitutional work, and the reason the framers preferred it to Federation is exactly what this question tests. Contrast the American model, formed by a compact among pre existing states with an implied right of exit, against the Indian model, formed by an indestructible Union. Comparative framing is the fastest route through questions on the nature of Indian federalism.

    The distribution of powers between the Centre and the States in the Indian Constitution is based on the scheme provided in the

    1. Morley-Minto Reforms, 1909
    2. Montagu-Chelmsford Act, 1919
    3. Government of India Act, 1935
    4. Indian Independence Act, 1947
    Show answer

    Answer: C. Correct Answer: Government of India Act, 1935 The distribution of powers between the Centre and the States in the Indian Constitution is largely based on the Government of India Act, 1935. This Act introduced a federal scheme with separate lists of subjects. Explanation 1. Morley-Minto Reforms, 1909 — Incorrect The Morley-Minto Reforms mainly expanded legislative councils and introduced separate electorates for Muslims. They did not provide a federal distribution of powers between the Centre and provinces. 2. Montagu-Chelmsford Act, 1919 — Incorrect The 1919 Act introduced dyarchy at the provincial level. It divided subjects into Central and Provincial categories, but it did not establish a proper federal distribution of powers like the present Constitution. 3. Government of India Act, 1935 — Correct This Act provided for an All-India Federation and introduced a three-fold division of legislative powers. It had Federal, Provincial and Concurrent Lists, which influenced the present Union, State and Concurrent Lists. 4. Indian Independence Act, 1947 — Incorrect This Act mainly dealt with partition and transfer of power to India and Pakistan. It did not create the scheme of distribution of powers between the Centre and States. Extra UPSC Info * The Government of India Act, 1935 is the most important source of many features of the Indian Constitution. * It introduced the idea of a federal structure, though the federation never fully came into operation. * The present Constitution distributes subjects through the Seventh Schedule. * Article 246 deals with the distribution of legislative powers between Union and States. * Article 248 gives residuary powers to Parliament. * Under the 1935 Act, residuary powers were with the Governor-General. * The Indian Constitution gives a strong Centre, influenced partly by the Canadian model. Final Takeaway The present Centre-State distribution of powers in India is mainly derived from the Government of India Act, 1935.

Entry 81 of the Union List mentions Inter-State migration and inter-State quarantine. Option (c) – CORRECT: Inter-State quarantine is a Union subject under the Union List (Entry 81). Option (d) – INCORRECT: Corporation Tax is Entry 85 in the Union List — it is a Union subject, not a State subject. Hence option (c) is the correct answer.
