The Haryana government is planning to build a dam at a cost of Rs 6,134 crore, with the aim to prevent floods caused by the Yamuna in Delhi and adjoining areas in Haryana.

The 14-km-long reservoir will be built 4.5 km upstream from the Hathnikund Barrage in Yamunanagar district. Once the project is completed, its reservoir will have a capacity of 10.82 lakh cusecs, which will enable the availability of additional irrigation water, groundwater recharge, apart from generation of 250 MW electricity in the state. The reservoir water is expected to irrigate nearly 2.24 lakh acres in Haryana and other states during rabi crop season, from October to December.

The initial survey of the proposed dam has already taken place in the areas concerned in Haryana and Himachal Pradesh. To make way for the dam project, nine villages will be displaced along with shifting of an 11-km stretch of NH-73.
