Construction of Dams
Majority of the projects in Arunachal Pradesh are Run of the River projects with limited pondage and are unlikely to have any major impact on the average flow pattern in the River. Some of the proposed storage dams in Arunachal Pradesh with flood cushion will reduce the possibility of downstream flooding to a certain extent during the flood season.

The Ministry of Environment & Forests prescribes minimum environmental flow to be maintained for the downstream stretches of river for maintenance of aquatic ecology for all river valley and hydro power projects, while granting mandatory environmental clearance under the Environment Impact Assessment (EIA) Notification, 2006. Further, an Environment Impact Assessment study of Siang and Subansiri sub basins of River Brahmaputra in Arunachal Pradesh is undertaken by Central Water Commission to assess the cumulative impacts of hydropower development in these basins including downstream impact on Assam.

This information was given by the Minister of State for Water Resources and Minority Affairs Shri Vincent H. Pala in a written reply to a question in Lok Sabha today.
