1. Why is the Kishau Dam So Important?

The Kishau Dam is a massive infrastructure project designed to capture and store the heavy monsoon rains in the upper mountains.

• Where is it?: The 232-meter-high concrete dam will be built on the Tons River (the Yamuna’s biggest tributary), sitting right on the border of Himachal Pradesh and Uttarakhand.
• Power and Farming: Once finished, it will generate 422 MW of clean electricity and provide enough water to irrigate over 97,000 hectares of farmland across northern India.
• Stopping Water Waste: Right now, because there are no dams in the upper mountains, 75% of the Yamuna’s rainwater simply flows away. This causes deadly floods during the monsoons and severe water shortages in the summer.

2. How the 8-Year Fight Was Finally Resolved

For eight years, the project was stuck because states were arguing over who would pay for it and how to compensate the displaced villages.

• The Money Fight: Earlier rules forced mountain states like Himachal Pradesh to pay hundreds of crores for the dam, even though lowland states like Haryana were getting most of the water.
• The 90:10 Solution: The Central Government finally stepped in and declared it a “National Project.” Now, the Centre will pay 90% of the massive cost, while the six benefiting states just share the remaining 10%.
• Sharing the Water: The saved water has been carefully divided. Haryana gets the most to boost its farming, while Delhi gets a guaranteed supply to help solve its daily drinking water crisis.
