Alaknanda

Dams have reduced the Alaknanda to a trickle and altered the socioeconomic fabric of the villages in its course. A living entity status may just save it from damnation.

The river Alaknanda holds a special, sacred place for Indians. One of the two headstreams of the holiest river Ganga, Alaknanda originates from glaciers at the head of the Alaknanda valley in Uttarakhand's Chamoli district. It runs a 190-km-course in the state's hilly districts of Pauri Garhwal, Rudraprayag and Tehri before merging with Bhagirathi that originates from the Gangotri glacier in the Himalayan state's Uttarkashi district.

This study of the water quality of the Ganga was commissioned after the construction of the Tehri Dam. It acknowledges that most people in India have a belief that water from the Ganga has bactericidal properties and this might be affected by the dam. National Environmental Engineering Research Institute (NEERI) was retained by the Tehri Hydro Development Corporation Limited (THDC) to investigate any impact that the Tehri Dam might have on the water quality of the Ganga. This report presents the results of that investigation.

Studying the environmental impact of Phata-Byung & Singoli-Bhatwari hydro power projects on the river Mandakini. Is it actually a threat?

This report by MoEF regarding the environmental impact of Phata-Byung & Singoli-Bhatwari hydro power projects on the river Mandakini deals with the additional safeguards and proper monitoring & supervision to help protect the environment in these project areas. It says that since a fairly large portion of the works has been taken up it may not be worth to abandon the project. It has proposed certain remedial measures to mitigate the damage if caused to the environment and local villagers. 

The Phata-Byung and Singoli-Bhatwari hydro power projects, are Run of the River (RoR) projects on the river Mandakini. The series of RoR projects proposed and under construction as a part of cascade development are to generate electrical energy which is considered to be clean power as it is non-polluting and renewable in nature.
