The Haryana government is planning to build a dam at a cost of 6,134 crore rupees. It will have a 14-km-long reservoir and will be built 4.5 km upstream from the Hathnikund Barrage in Yamunanagar district. Once the project is completed, the state will have greater availability of irrigation water, groundwater recharge, and aquaculture, apart from generation of 250 MW of electricity.

Its reservoir will have a capacity of 10.82 lakh cusecs. This is likely to prevent floods caused by the Yamuna in Delhi and in adjoining areas of the river in Haryana. The dam area also shares borders with Uttarakhand and Uttar Pradesh.

Last month the Chief Minister informed that the proposal to construct a dam behind the Hathnikund Barrage is being taken up with the Himachal government.  He said that it will help to check the floods caused by excessive rains.
