Highest Dam in India 2022

Highest Dam in India is located in which state?

A dam acts like a barrier that stops the flow of water, which makes a water reservoir. The water reservoir is used to generate electricity. The electricity produced by this process is called hydroelectricity. The reservoir is not only used for generating electricity, but it is also used for irrigation and aquaculture, and it also suppresses the formation of floods. The dam is designed in such a way that it preserves water and also uses the proper method to execute the controlled release of water.

Highest dam in India- Height, River and State

The Tehri Dam is the highest in India, it is about 260.5 meters high and 592 meters long. The Tehri dam and hydropower plant are used for hydroelectricity generation and irrigation purposes. Tehri dam is across the Bhagirathi River in Uttarakhand, India.

The construction of the Tehri dam began in 1978, but the investigation and design were completed in 1961 and 1972 respectively. The delay in the construction of the dam was caused due to financial and economic impacts. The construction of the Tehri dam was under the supervision of the irrigation department of Uttar Pradesh. Later in 1988, Tehri Hydro Development Corporation was formed to manage the dam. The funds were divided into two, 75% was provided by the federal government and 25% from the state.

Tehri Dam is about 855 ft and its length is 1,886 ft, the width of the dam is 66 ft, and the width of the base is 3,701 ft. The reservoir created by the dam is about 3,200,000 acre-ft or 4.0 cubic kilometers. The hydro capacity installed in the dam is 1000 MW, with 1000MV of storage hydroelectricity pump.

Both the Tehri dam and Tehri pumped-storage hydroelectricity power plant are part of the Tehri Hydropower Complex. The total expenditure of this project under the Tehri Hydropower Complex was 1 billion USD. Power generated from the reservoir is distributed all around northern India. It includes the states like Jammu and Kashmir, Himachal Pradesh, Uttrakhand, Uttar Pradesh, Punjab, Delhi, Haryana, Rajasthan, and Chandigarh.

With every good project, there are a lot of objections against it. Similarly, when Tehri Dam was founded, a person named Virendra Dutt Saklani formed the Anti-Tehri Dam struggle committee. From the 1980s to 2004 this committee was led by environmental activist Sunderlal Bahuguna. The main reason for the protest was the displacement of the inhabitants of the place where the dam was being built and the environmental cause like deforestation and pollution of water.

How electricity is produced in Dams?

Dams are generally used for electricity generation and other water-related purposes like irrigation, flood management, water management, etc. The dams block the flow of water and make a reservoir, this reservoir helps in generating electricity. At the bottom of the reservoir, a turbine propeller is installed. The water pressure which passes through the spinning turbine generates power. The power generated from the turbine is used to generate electricity.

Types of Dams

There are many types of dams found in India. Based on the structure the dams are of the following types

  1. Gravity Dam- Gravity Dams are dams constructed with concrete and stone masonry. The mechanism is very simple, the dams are designed in such a way that it holds back water by using the weight of the material only. It is designed in such a way that every section of the dam is independent of the other section.
  2. Arch Dams – it is a concrete dam that is curved upstream. The arch Dams are designed in such a way that the force of water or hydraulic pressure, presses against the arch which straightens the arch and gives strength to the structure. For narrow canyons or Gorges with steep walls, arch Dams help to support the structure and are most suitable for that type of water body.
  3. Arch-Gravity Dams – It is made from both the characteristics of arch and gravity dams. The dam is curved upstream which directs the water pressure against the walls of the canyons.
  4. Embankment Dams- It is large artificial dams. A semi-plastic mound of many compositions of soil, sand, and clay is used to create artificial dams. It is waterproof.
  5. Earth-fill Dams- These are constructed similar to embankment Dams but with well-compacted earth. It is called earthen dams or rolled earth dams or earth dams.
