Arunachal Pradesh has informed the Centre that downstream impacts can be studied during construction of the 1,750MW Lower Demwe project which should be cleared as it will not affect Dibru-Saikhowa National Park in Dibrugarh district of Assam. “The downstream impacts are limited to a few months of the lean season and will be confined to low-lying flood plains in the Brahmaputra basin. These impacts can always be studied during construction of the project.
