INTRODUCTION
The Srinagar Hydroelectric project was cleared by the Environment Ministry in 1987, and its capacity was increased to 330 MW in 1995. Alaknanda Hydro Power Company undertook development of the Srinagar Hydroelectric Plant located on the Alaknanda river in the state of Uttarakhand. The objective of the project was to increase the generation capacity of the plant to 330MW, achieved by utilizing a head of 66m and design discharge of 560m3/s. The project included a 95m high concrete gravity diversion dam with 12 spillway bays, two 1km long head race tunnels, a 3.05km concrete lined power channel, a forebay, a by-pass channel, four 114m penstocks, a surface powerhouse, a switchyard and tail race channel.
Environment impact:
This project is an impounded type hydro power project and it has a large dam to store the water as shown in the picture above. So the river length that will be affected by this project is 4500 meters, the forest land taken for project is 339 ha and the area that will be submerged by the reservoir is 68.73ha. The submergence area of the Srinagar Hydroelectric project starts from an elevation of about 500m above sea level at the dam site near Koteswar and extends up to an elevation of 600m above sea level near village Narkota
