Lakhwar-Vyasi Dam project on Yamuna River, includes under-construction Lakhwar Dam and Power Station, Vyasi Dam, Hathiari Power Station and Katapathar Barrage, near the Lakhwar town in Kalsi block of Dehradun district of Uttarakhand in India, for the purpose of irrigation of 40,000 hectare land and total 927 MW hydroelectric power generation. "Lakhwar Dam" is a gravity dam near the Lohari village with 300MW power generation capacity. "Vyasi Dam" will be built 5 km downstream along with 120 MW "Hathiari Power Station" further 0.5 km downstream. "Katapathar Barrage", with the maximum ponding water level at 514.5m elevation, will be built further 2.75 km downstream of the Hathiari Power Station to supply the water to stakeholder states. Project will hold 580 million cubic metres water during monsoon and release into Yamuna during dry months.
Construction of Lakhwar dam commenced in early 2018 with the 4 year target completion date of December 2022. Vyasi dam has already been under construction since 2016.
