The site of the Tehri Dam was chosen in 1961. It was an urban center on the banks of the river Bhaghirthi, one of the three rivers which join at Deoprayaga to form Ganga. The plan also envisages another dam named Koteshwari Dam. The project is being looked after by Tehri Hydro Development Corporation. The Government of India and Government of Uttranchal are the joint partners of this corporation. The Planning Commission had sanctioned the Tehri Dam in 1972. The work on the dam started in 1978. The land was acquired in 1976. The Koteshwari Dam will be started only when Tehri Dam will be completed. Hence, there will be two reservoirs on Bhagirithi River before it joins Alaknanda River at Deoprayaga.
In 1980, the then prime minister of India, Indra Gandhi, again got it reviewed. At that time, the committee under Dr. S. K. Roy strongly ruled against the project and the project was abandoned. It is on record that there is a comment by Prime Minister Indra Gandhi on the file that the project would benefit only the contractors.
In 1987-88, this project was reviewed by the government of the time. At that time, the Soviet Union showed interest in it. The standing committee of Ministry of Environment and Forest of Government of India again ruled against it. However, the Government of India overruled the recommendation of the ministry and sanctioned the project.
Even before that, this site was chosen for making a dam by the British Indian Government. However, due to strong opposition by the people and under the leadership of Madan Mohan Malvia, it was abandoned.
The site stands on seismic activity which when come into play may create a earthquake of the magnitude of 8 to 9 on the Richter scale of 12.
The dam will impound 700 billions gallon of water. The height of the dam will be 260.5 m. The dam will produce nearly 2400 MW of power. It will also facilitate irrigation of nearly 2.6 lakh hectares of agricultural land. It will provide the 270 million gallons of drinking water to Uttranchal, Uttar Pardesh and Delhi. The life span of dam is estimated at 30 years from 2015 onwards. After that, it has to be abandoned due to siltation.
The electricity generation machinery is being provided by Voith Siemens. The construction work is being carried out by JP Industries.
On December 5, 2001, the impounding of the water has started.
The Controversies and Issues:
Since the day of inception of this plan the project has been embroiled in controversies.
The first issue came in form of concern for the environment and preservation of flora and fauna. There was strong demand for environment studies that should be carried out and also need for the clearance from the environment ministry. However, the clearance of environment ministry came in 1990.
The second major issue was the location of the project and the design of the dam. It is still strongly contended that the dam stands in a seismic sensitive area and will cause great damage in case of earthquake. Related to this issue is the design of the dam which is made to withstand Peak Ground Acceleration of 0.25 g. It is argued at in case of a earthquake of the magnitude of 8, the PGC will be 1.0 g. In addition to that, there are regular landslides which will be cause of increased siltation reducing the total life span of the dam before the estimated age of the dam. Further, the cost of generation of electricity will be more than what is being generated from other hydroelectric units. It is argued on the basis that the cost of raising the dam has already increased to a level that it will be not profitable at all for the Uttranchal government. It is further argued that beneficiary states in case of irrigation and electricity will only be Uttar Pardesh and Delhi.
The third issue is the rehabilitation of the displaced people. It is strongly protested in the press media that the government is not keeping its promise in rehabilitating nearly one lakh people displaced in and around Tihari. However, the rebahilitation is being carried out as per the recommendation of Hanumantha Rao Committee. Hanumantha Rao Committee was established in 1996 after environmentalist Shri Sundar Lal Bahuguna went on hunger strike. The recommendations of Hanumantha Rao Committee was accepted in 1997. However, the dam has displaced a large number of people and created a major social problem for the area which requires compensation more than what the committee has recommended. The Janmanch has given an extensive report on the Resettlement and Rehabilitation.
The fourth issue is the emotional and religious issue which comes again and again in form of headlines. It is belief of Hindus that the three streams which join to form Ganga are vital for the present characteristics of the water of Ganga. When the dams will be raised on Bhagirithi and Alaknanda (Which is the second project after Tehri), the water will be entrapped for a longer period. That will destroy the original purity of the water of Ganga. They argue that only the flowing water will ensure the purity of the water of Ganga. The second issue is that Bhagirith had brought down the river Ganga for the salvation of his ancestors. It is a matter of belief that the same credit is gained by all the followers of Vedic religion (Hindu Religion). As per mythology, any obstruction or stopping of Ganga at any stage will bring catastrophe for the region. There are some stories in Puranic literature which tells that in case Ganga disappears, it brings great hardship for the people of the region.
The fifth controversy is that there is a section of experts who say that there is not need of raising huge dams. They claim that it is there expeerience that such huge dams are not profitable in long run as they cause more environmental harm. Ramaswamy Iyer of the Center for Policy Research in New Delhi is strongly against such big dams. He believes that water harvesting is the better answer. (Quoted from a report of Don Oko given on the website of www.grist.org)
The sixth controversy is the corruption and embezzlement while undertaking the rehabilitation and resettlement.
