Impact:
Over 100 000 people were displaced by the dam.
Ecological Issues: Drowned forest site and associated wildlife.
Challenges:
FACED DELAYS, LEGAL DISPUTES, AND ENVIRONMENTAL PROTESTS. There is a seismographic dread over the place as it is posed near fault lines. Tourism: People come here by tourism because of damming and the water sport facility. Tehri Dam, an important core structure of energy and water infrastructure in India, raises heated debates regarding its environmental and social consequences.
Highest Dam In India Lakhwar Dam
Lakhwar dam is considered one of the major water storage and hydroelectric projects on the Yamuna river in Uttarakhand, India. The major points in respect of Lakhwar Dam are:
Location: Situated on the Yamuna River at the Jaunsar Bawar district, Uttarakhand near the village Lakhwar.
Objective:
Hydroelectric Power: The dam offers hydroelectric power, and its potential capacity is nearly 300 MW.
Water Supply: It looks forward to offering irrigation water to agriculture within the area.
Flood Control: Controls runoff while minimizing the potential of flooding downstream.
Construction
The project was planned so long back; in fact, the construction work was even carried out back in the 1980’s but did face setbacks thereafter.
It is under development by the Uttarakhand Jal Vidyut Nigam Limited (UJVNL).
Design:
Type: The dam would be of a concrete gravity type, and it would be approximately 204 meters high. Reservoir: The dam will create the reservoir which is expected to hold much water for irrigation and hydroelectric generation.
Impact:
Displacement: The dam would displace a certain number of villages in the project area.
Environmental Concern: This would be a concern for the local ecosystems, being a wildlife-and vegetation-related affair along the river.
Problems: Funding and delays: This project has attracted more setbacks due to financial problems, environmental issues, as well as those created by politics. Seismic Risk: Lakhwar Dam, like most projects in the region, is situated on a seismically active zone and has a resultant risk factor for earthquakes.
Highest Dam In India Idukki (Eb)/Idukki Arch Dam
One of the fabulous engineering marvels in India is the Idukki Arch Dam located in the Idukki district of Kerala. Here are the key points about the Idukki Dam:
Location:
Being in the south Indian state of Kerala’s district of Idukki along the Periyar River.

Objective:
Hydroelectric Power Generation: The dam generates considerable power for northern India with an installed capacity of about 1,325 MW.
Irrigation: It has been an essential source of irrigation for the arid regions of Punjab, Haryana, and Rajasthan.
It manages flood waters to regulate the waters of the Sutlej River.
Building:
The construction of the Bhakra Dam started in 1955 and was completed in 1963.
It is a joint organization between the central and state governments, constructed by the Bhakra Beas Management Board.
Agriculture: It has transformed agricultural practices in the states of Punjab, Haryana, and Rajasthan into a more productive practice, especially for crops such as wheat and rice.
Displacement: The construction activity resulted in displacing a large population in the surrounding vicinities.
Environmental Considerations: The dam changed the flora and fauna of that region but contributes to water conservation.
Problems
Seismic Activity: The area is seismically very active; however, the dam has been designed to resist all such hazards.
Maintenance: The dam would require routine maintenance in order to be operated safely and effectively. Tourism: Bhakra Dam is one of those highly visited tourist destinations because of their sheer size and picturesque surroundings.
Highest Dam In India Pakal Dul Dam
Pakal Dul Dam is one of the most prominent hydroelectric projects in the country and located in the Jammu and Kashmir region of India. As such, it falls amongst the significant infrastructure projects being developed in the region. The important points regarding the Pakul-Dul Dam are as follows:
Location:
Located on the Chenab River in the Doda district, northern India, in the state of Jammu and Kashmir.
