During the night of June 20, 2020 pre-monsoon showers left series of gully formations on one of the muck dump sites of the under construction 120 MW Vyasi Hydro Electric Project (HEP) in Hathiyari area of Vikas Nagar tehsil, Dehradun district in Uttarakhand. Huge amount of muck washed down into Yamuna River, exposing the credibility of the Uttarakhand Jal Vidyut Nigam Ltd. (UJVNL), the developer of Vyasi HEP.
Local people said that since June 2019, the UJVNL has spent over Rs. 40 lakh on geo jute and hydro seeding (grass slope protection) work at Hathiyari muck dumping yard. The project has already missed several deadlines, the work is far from complete. The careless handling of muck generated during the construction of 2.7 km long, 7-m dia tunnel in last eight years has added -+to the woes of local people and Yamuna river.
