Tipaimukh Dam is a proposed embankment dam on the river Barak in Manipur state India, first commissioned in 1983. The purpose of the dam is flood control and hydroelectric power generation. It has been subject to repeated delays as the project developed, as there has been controversy between India and Bangladesh over water rights, in addition to questions of environmental effects of the huge project, as well as the need to relocate indigenous Hmar people to make way for a vast reservoir. [1] In 2013, the governments of India and Bangladesh announced further delays, as the latter nation undertakes additional studies about expected effects and mitigating measures.


Technical features

The dam is planned to be 390m long and 162.8m high, across the Barak River, which enters Bangladesh below the proposed dam location. The dam's crest elevation will be at an altitude of about 180 m. above mean sea level, with a maximum reservoir level of 178 m. The dam was originally designed for flood control, to contain waters in the lower Barak valley. Hydro-power generation was later incorporated into the project. The project will have an installation capacity of 1500 MW, supplied by six 250 MW Francis turbine-generators. [2]


Bangladeshi experts have said the massive dam will disrupt the seasonal rhythm of the river and have an adverse effect on downstream agriculture and fisheries. [3] The government of Bangladesh has decided to send an expert team to the dam area to examine the features and likely impact of the dam on the flow of water into the Surma and the Kushiara.

Another is the environmental factor. The Tipaimukh area lies in an ecologically sensitive and topographically fragile region. It is within one of the most seismically volatile regions on the planet. A major earthquake of magnitude of 6.6 on the Richter Scale rocked Manipur-Myanmar border on 6 August 1988 at the epicenter of lat. 25°7′48″N95°9′0″E / 25.13000°N 95.15000°E / 25.13000; 95.15000 , 240 km (150 mi) northeast of the dam site. [4]

In 2013 the two governments announced up to a 2-year delay, to allow Bangladesh to complete additional environmental studies.

Loktak Lake Lake in North East India

Loktak Lake is the largest freshwater lake in India. It is a pulsating lake, with surface area varying from 250 sq km to 500 sq km during rainy season with a typical area of 287 sq km. The lake is located at Moirang in Manipur state, India. The etymology of Loktak is Lok = "stream" and tak = "the end".It is famous for the phumdis floating over it. The largest of all the phumdis covers an area of 40 km2 (15 sq mi) and is situated on the southeastern shore of the lake. Located on this phumdi, Keibul Lamjao National Park is the only floating national park in the world. The park is the last natural refuge of the endangered Sangai, Rucervus eldii eldii or Manipur brow-antlered deer, one of three subspecies of Eld's deer.

Indian rivers interlinking project Project to interlink rivers of India

The Indian Rivers Inter-link is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking Indian rivers by a network of reservoirs and canals to enhance irrigation and groundwater recharge, reduce persistent floods in some parts and water shortages in other parts of India. India accounts for 18% of the world population and about 4% of the world’s water resources. One of the solutions to solve the country’s water woes is to link rivers and lakes.

The Indira Sagar Dam is the largest dam in India, in terms of volume of water stored in the reservoir. It is located on the Narmada River at the town of Narmada Nagar, Punasa in the Khandwa district of Madhya Pradesh in India.

The downstream projects of ISP are Omkareshwar, Maheshwar, and Sardar Sarovar Project. To build it, a town of 22,000 people and 100 villages were displaced.

Barak River

The Barak River flows 900 kilometres (560 mi) through the states of Manipur, Nagaland, Mizoram and Assam in India. Further it enters Bangladesh where it is known by the name of the Surma and the Kushiyara and later called the Meghna before receiving the combined flow of the Ganga and the Brahmaputra. It flows into the Bay of Bengal via Bangladesh. Of its length 524 km (326 mi) is in India, 31 km (19 mi) on the Indo–Bangladesh border and the rest is in Bangladesh. The upper part of its navigable part is in India — 121 km (75 mi) between Lakhipur and Bhanga, declared as National Waterway 6, (NW-6) since the year 2016. It drains a basin of 52,000 km2 (20,000 sq mi), of which 41,723 km2 (16,109 sq mi) lies in India, 1.38% (rounded) of the country. The water and banks host or are visited by a wide variety of flora and fauna.

Salal Dam Dam in Jammu and Kashmir

Salal Dam, also known as Salal Hydroelectric Power Station, is a run-of-the-river hydropower project on the Chenab River in the Reasi district of the Jammu and Kashmir. It was the first hydropower project built by India in Jammu and Kashmir under the Indus Water Treaty regime. After having reached a bilateral agreement with Pakistan in 1978, with significant concessions made to Pakistan in the design of the dam, reducing its height, eliminating operating pool, and plugging the under-sluices meant for sediment management, India completed the project in 1987. The concessions made in the interest of bilateralism damaged the long-term sustainability of the dam, which silted up in five years. It currently runs at 57% capacity factor. Its long-term future is uncertain.

Run-of-the-river hydroelectricity Hydroelectric power station

Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture.
