Key takeaways

  • Six northern states signed a historic agreement to construct the Kishau Multipurpose Project on the Tons river along the Uttarakhand-Himachal Pradesh border.
  • Under a cooperative federalism framework, Delhi and Rajasthan agreed to pay Himachal Pradesh's Rs 2,000-crore power component liability in a 75:25 ratio.
  • The 422-MW project will generate 1,476 million units of electricity and bring irrigation to 97,000 hectares of farmland.
  • Delhi will receive 110 MCM of drinking water, and 25% of the project water is reserved for Yamuna river environmental flow to support the 2029 clean Yamuna target.

Why in News

  • Six northern states signed a historic Memorandum of Understanding (MoU) to clear the long-pending Kishau Multipurpose Project.
  • The states involved include Uttarakhand, Himachal Pradesh, Uttar Pradesh, Haryana, Rajasthan, and Delhi.
  • This agreement resolves a major dispute regarding cost-sharing and water allocation among Yamuna basin states.

Background and the 1994 Yamuna Agreement

  • In 1994, Yamuna basin states signed an agreement to allocate the surface water of the Yamuna river.
  • The Upper Yamuna stretch from Yamunotri glacier to Okhla barrage lacked major water storage structures.
  • To fix this, the 1994 agreement identified three storage projects: Lakhwar in Uttarakhand, Renukaji in Himachal Pradesh, and Kishau on the HP-Uttarakhand border.

Key Features and Funding Disputes

  • The Kishau Multipurpose Project involves building a 232.6-metre-high concrete gravity dam on the Tons river, a main tributary of the Yamuna.
  • As a designated National Project, the Central Government funds 90% of the water component, while basin states share the remaining 10%.
  • A major deadlock arose over the Rs 2,000-crore power component, which Himachal Pradesh refused to pay due to local ecological and displacement burdens.

Resolution Through Cooperative Federalism

  • The financial deadlock was solved through cooperative federalism among the participating states.
  • Downstream beneficiary states agreed to cover Himachal Pradesh's power liability to ensure project progress.
  • Delhi and Rajasthan agreed to pay this Rs 2,000-crore liability in a 75:25 ratio based on their drinking water benefits.

Socio-Economic Impact and Environmental Benefits

  • The 422-MW project will generate 1,476 million units of hydropower and irrigate 97,000 hectares of farmland.
  • Delhi will receive 110 million cubic metres (MCM) of water to fulfill its long-term drinking water requirements.
  • The project reserves 25% of its water flow strictly to maintain the environmental flow of the Yamuna river under the National Mission for Clean Ganga (NMCG) target for 2029.
