The Himachal Pradesh High Court has restrained the Shanan Hydroelectric Project from conducting de-silting at the Barot site before March 1 each year to safeguard the trout breeding season. This decision was made to prioritize environmental rights over economic gains. The court also mandated scientific monitoring of sediment discharge and ordered a payment of Rs 12 lakh for the restoration of trout populations.
The court took action after concerns were raised about silt discharge from the Barot dam degrading water quality and harming aquatic life in Mandi district. It was observed that the project had been carrying out de-silting activities during the trout breeding season for economic reasons, despite recommendations against it. The court emphasized the need to protect marine life and balance power generation concerns with ecological preservation.
To ensure future compliance, the court directed the installation of sensors to monitor Total Suspended Solids levels during de-silting activities. Additionally, the Fisheries Department was tasked with overseeing the release of minimum water discharge during lean flow periods and verifying that water is not being stored by the project. A River Monitoring Committee will be established to advise on de-silting timing and methods, with a focus on protecting trout-rich areas.
The court also ordered the project proponent to deposit Rs 12 lakh for the phased stocking of Brown Trout and Rainbow Trout, with the possibility of using the funds for broader aquatic restoration efforts. It highlighted the ecological harm caused by previous desilting activities and stressed the importance of upholding environmental responsibilities.
