The impacts due to hydropower development, especially reservoir and dams are always space extensive which covers catchment area of upstream, downstream and on site surrounding area of plants. Generally, HEPs in Kinnaur district have been given all attention regarding its technical design, economical issues and very least or almost negligible attention on social and environmental factors.
