Tehri Dam


Tehri Dam is the primary dam of the Tehri Development Project, a major hydroelectric project centered near Tehri Town in the state of Uttaranchal in India. Located on the Bhagirathi River, the principal tributary of the sacred River Ganges, the Tehri Dam has a height of 855 feet (261 m), making it the 5th tallest dam in the world.

The dam's intended capabilities include a power generation capacity of 2400 MW, provision of irrigation to an area of 270,000 hectares, irrigation stabilization to an area of 600,000 hectares, and a supply of 270 million gallons of drinking water per day to the industrialized areas of Delhi, Uttar Pradesh and Uttarakhand. There is another smaller dam 14 km downstream at Koteshwar that will produce 400 MW of electricity, and is still considered part of the TDP hydroelectric plan.

Terrorist may attack on the tehri dam.

I had already indicated that since Tehri dam plans to store water over a depth of 850ft. (260meters) any bombing by the agents of enemy countries or militants or terrorists, the dam being made of earth, sand and gravel will easily collapse, killing millions of Indians and destroying holy temples and sacred towns and cities as stated already. Crops, buildings and properties estimated at more than several lakh crores of rupees will be destroyed. In view of the latest terrorist attack on the World Trade Centre and Pentagaon buildings in USA a similar attack by terrorists, militants or enemies on Tehri dam should be anticipated because it will be an inexpensive bid for them to easily destroy the life and culture of the whole of Aryavartha.


Infact Dr.Narendrapuri, Professor of Structural Engineering, Roorkee University presented an animated picture before Dr.M.M.Joshi and our committee members as to how the Westerns bombed one of the dams when flash floods caused large scale destruction of human and animal populations and properties on the down stream side of the broken dam.


As it is the Tehri dam is under-designed and very unsafe. But some of the proponents of the dam who have vested interests in the project are misleading the secretaries to the Government who inturn are misleading the Prime Minister to take unscientific and hazardous decisions to continue work on the Tehri project even though it is highly detrimental to the life and culture of people of India in general and the Gangetic states in particular. Tehri dam is an easy target for terrorists to ruin the economy of India and thereby threaten the national security, promote the growth of poverty, unemployment and violence in this holy land of Buddha, Mahavir and Mahatma Gandhi.


Surprisingly the Union Ministry of Power in its letter dated 10-4-2001 on the constitution of the expert committee to examine the seismic safety of Tehri dam in the light of the Bhuj Earthquake under the chairmanship of Dr.M.M.Joshi states that the Tehri dam is safe to withstand the maximum credible earthquake as per the experts. There is lot of misunderstanding among the experts as to what exactly is meant by the seismic safety of Tehri dam because most of the experts who pronounced judgements on the issue have taken academic degrees in the collateral but not the relevant seismic and environmental safety fields of study and hence their decisions are bound to be imperfect, unscientific and harmful to national interests.



According to law an expert opinion becomes relevant for right decision, if only it conforms to certain fundamental norms. According to sec.45 of the Evidence Act, a person specially skilled, is considered as an expert. When the court has to form an opinion upon a point of science, art or engineering, the opinions upon that point of such persons who are specially skilled in such science, art or engineering are relevant facts. But an expert in order to become a competent witness need not acquire special knowledge or skill professionally because it is enough if he made a special study of the subject or acquired special experience therein.

Before the testimony of a person becomes acceptable his competency as an expert must be proved, may be by showing that he possesses the required qualification or that he has acquired skill therein by experience. An expert should be subjected to cross examination because like any other witness, the expert is fallible and the real value of his evidence consists in the rightful inferences which he draws from what he himself has observed and not from what he merely surmises. Facts which are not otherwise relevant become relevant, if they support or overthrow the opinion of experts when such opinions are relevant.


Where the opinion of an expert is to be acceptable, the grounds or reasoning upon which such opinion is based may also be inquired into. Opinion is no evidence, without assigning the reason for such opinion. The correctness of the opinion can better be estimated in many instances when the reason upon which is it is based are known. If the reasons are frivolous or inconclusive, the opinion is worth nothing. While the value of non-expert witness depends upon the credibility of the witness (i.e. his inclination and capacity of telling the truth), the value of opinion of an expert depends largely on the cogency of the reasons on which it is based, and the competency of the expert to form a reliable opinion. An expert opinion cannot be the basis for decision-making, unless the expert opinion is also corroborated by other evidence.

Tehri (Uttrakhand), July 10 (ANI): Delay in monsoons has decreased the water level in the Tehri Dam, significantly leading to a fall in the production of electricity. The Tehri Dam, one of the biggest in the country, provides drinking water and electricity to Uttarakhand, Delhi and Uttar Pradesh. The reservoir is currently down by six metres. “There is water scarcity due to which the electricity production has been affected,” said A.I. Shah, general manager, Tehri Dam. ” Last year we were producing 10 million units of electricity, but this time, it has reduced to four million units. If it does not rain, the situation will only worsen,” he added. The dam provides irrigation to an area of 270,000 hectares. Located on the River Bhagirathi and situated at a height of 855 feet, it is the one of the tallest dams in the world. The dam has a power generation capacity of 2400 MW, and supplies 270 million gallons of drinking water. (ANI)

Tehri dam: Power generation from March December 19, 2005 15:05 IST After 17 years and Rs 7,300 crore (Rs 73 billion) of investment, the countdown has finally begun for power generation in Tehri Dam and Hydro Power Plant, India's [ Images ] largest and yet one of the most controversial hydroelectric projects. The water level at the reservoir is expected to touch the magical 720-metre mark, crucial to start power generation in March 2006. "We are giving final touches to our preparation for the test power generation in March next. The water level in the dam has already touched 702 m height. As soon as it gets to the 720 m mark, we will turn keys for test generation," S K Shukla, general manager, Tehri Hydro Development Corporation Ltd (Project) told PTI. On Sunday, the lower reach of old Tehri town, which houses a college, a market and residential areas, was submerged and water level was estimated to be rising by 40 cm per day. While green activists have been opposing the project citing environmental concerns, rights activists want the displaced people to be properly compensated.
