Top 10 Largest Dams in The World

Dams play a major role in providing a proper structured outlet for water gushing out with great pressure around waterfalls and major rivers. Along with keeping the neighbouring cities safe from floods, it is also crucial for sending water and hydroelectric power to a lot of cities in its dire need. So, here is a list of the top 10 largest dams in the world 2019.

Guri, the world’s fifth biggest dam, has a storage capacity of 135 billion cubic metres and creates the Guri Lake covering 4,000km2. The concrete gravity and embankment dam measures 1,300m in length and 16m in height, and provides for 70% of the country’s electricity needs. It is operated by CVG Electrification del Caroni CA (Edelca).

4. Daniel Johnson Dam, Canada:

Largest Dams

The Daniel Johnson Dam, also known as Manic 5 Dam, impounds the Manicouagan River that creates the Manicouagan Reservoir with a storage capacity of 139.8 billion cubic metres. The reservoir, having a surface area of 1,973km2, is the fourth biggest in the world.The dam is also touted as the world’s biggest hollowbody multiple-arch-and-buttress dam. It is 1,310.6m long and 213.97m high, and features 14 buttresses and 13 arches. It was constructed using 2.2 million cubic metres of concrete. The dam is owned by Hydro-Québec and was constructed from 1959 to 1968. The dam’s two power stations feature 12 units with a combined installed capacity of 2,660MW.

3. Akosombo Dam, Ghana:

Largest Dams

Akosombo dam, located in Ghana, is the third biggest dam based on water storage capacity. Constructed on the Volta River, the dam creates the 8,500km2 Lake Volta, which is the world’s biggest reservoir by surface area. The lake impounds a mammoth 144 billion cubic metres of water.The rock-fill embankment dam has a crest length of about 700m and a height of 134m, and involved 12 million cubic metres of surface excavation. It was constructed from 1961 to 1966 primarily for the purpose of electricity generation, but also provides a livelihood for about 300,000 people through fisheries in the lake.

2. Bratsk Dam, Russia:

Largest Dams

Bratsk Dam in Siberia, Russia, ranks as the second largest dams in the world thanks to its 169.27 billion cubic metres reservoir. The dam impounds the Angara River and the reservoir created by it covers a surface area of 5,540 sq.kmThe concrete gravity dam is owned by Irkutskenergo and was constructed from 1954 to 1964 by Bratskgesstroy.

1. Kariba Dam, Zimbabwe:

Largest Dams

Kariba Dam is the world’s largest dams based on water storage capacity. Located at the former Kariwa (Kariba) Gorge, the dam creates Lake Kariba, which has a storage capacity of 185 billion cubic metres of water and a surface area of 5,580km2. The Lake Kariba covers a length of 280km and is 32km wide at its widest section. The double curvature concrete arch dam is owned by Zambezi River Authority and was constructed between 1955 and 1959 by Impresit of Italy. The dam is designed to avert a one in 10,000-year flood event.

This was the list of the top 10 largest dams in the world 2019 that have been built in view to serve the purposes of supplying water, and of course hydroelectric power, no doubt these dams play a major role in our lives. At least, these largest dams from the list surely do.
