BIGGEST GREAT 10 GOLD MINES BY RESERVES IN THE WORLD

A Gold mine is a place where gold is dug from the ground. Something that produces something desired (such as money). Gold mines remain important hubs of industry around the world as prospectors gamble on striking it rich with one of the world’s most valuable metals. Demand remains high for the precious metal, particularly in jewellery-making and as a relatively safe investment opportunity. Gold often occurs in free elemental form in rocks, veins and alluvial deposits in the form of nuggets or grains. A mine is a source of great wealth or profit. According to Mining Technology, Here are the 10 Biggest Gold Mines by reserves in the world in the year 2020.

1.Carlin, USA. 411 koz.

The Carlin Trend hosts one of the largest gold concentrations in the western hemisphere. Total Carlin’s production is 4% of world Production. Carlin deposits are 75% of US production. It has good hunting grounds for big deposits. On July 1, 2019, Barrick’s Goldstrike (including 60% share of South Arturo) and Newmont’s Carlin were contributed to Nevada Gold Mines and are now referred to as Carlin. This gigantic integrated operation located west of the city of Elko on the geologic feature known as the Carlin Trend, Stretching 56km (35mi). Nature concentrates the metals by a process of partially melting Crustal rocks at the depth, letting them melt arise through the crust and on the way cool and dumping valueless minerals such as Feldspars and amphiboles and then concentrating the useful minerals and metals in the remaining magma or hydrothermal fluid. Carlin–type gold deposits are sediment-hosted disseminated gold deposits. These deposits are characterized by invisible gold in pyrite and arsenopyrite. This dissolved kind of gold is called “Invisible Gold”, as it can only be found through chemical analysis.

  1. Olimpiada. 277 koz.

Located in one of Russia’s most prolific gold mining provinces, Olimpiada is largest gold mine in Russia, one of the largest gold mines on the globe. It is operated by Polyus. Olimpiada is Polyus’ largest gold operation and accounts for almost half of its total gold production. The company’s Olimpiada and Blagodatnoye mines are part of its Krasnoyarsk business unit, which is the second-largest gold asset in the world by output. The combined production from the two operations represents 63.7% of the company’s total gold output. This ore mined at the site is processed at three plants with a combined capacity of 13 million tonnes of ore annually. Olimpiada is located in the Severo-Yeniseysky District, 25km away from the village of Yeruda. The site is approximately 500km from the city of Krasnoyarsk in the Krasnoyarsk Territory of Western Siberia. It is situated at a distance of 20km from Blagodatnoye mine. Polyus Gold has claimed the Olimpiada gold mine is estimated to contain proven and probable reserves of around 28 million ounces. The mine produced 1.38Moz of gold in 2019 and 1.32Moz of gold in 2018.

  1. Pueblo Viejo, Dominican Republic. 238 koz.

The Pueblo Viejo mine is a gold mine located in the north-central region of the Dominican Republic in the Sanchez Ramirez Province. It is the largest gold mine in the Americas and eighth largest in the world. This mine produced 581,000 ounces of gold in 2018 and 6.55 million ounces of gold in reserve. The mine comprises two major oxide deposits known as Monte Negro and Moore and three other small deposits. The Pueblo Viejo mine in the Dominican Republic is about 100 km northwest of the capital city of Santo Domingo. The mine is operated by the Pueblo Viejo Dominicana Corporation — a joint venture between Barrick (60%) and Newmont (40%). Pueblo Viejo has a mine-life of more than 30 years and is expected to produce over one million ounces of gold per annum. It is the largest undeveloped gold mine in the world.

  1. Cortez, USA. 208 koz.

Cortez Gold Mine is a large gold mining and processing facility in Lander and Eureka County, Nevada, United States, located approximately 75 miles (120 km) southwest of Elko and comprises the Pipeline and South Pipeline deposits and the Cortez Hills deposit. Pipeline and South Pipeline are open pit mines, while Cortez Hills is an underground and open pit mining operation. On July 1, 2019, Cortez was contributed to Nevada Gold Mines, a joint venture between Barrick and Newmont Corporation. It consists of three distinct units: the Cortez open pit and two Carlin-type disseminated gold deposits – Pipeline and South Pipeline. The entire Pipeline complex contained 23 million ounces of gold between the original orebodies, the Pipeline orebody and the later discoveries of South Pipeline, Crossroads and Gap. It will also retain a contingent royalty interest in the future production of the property.

  1. Kibali, DRC. 202 Koz.

The Kibali gold mine is located in the northeast of the Democratic Republic of Congo (DRC), approximately 220 kilometres east of the capital of the Haut Uele province, Isiro, 150 kilometres west of the Ugandan border town of Arua and 1,800 kilometres from the Kenyan port of Mombasa. It is expected to produce 600,000oz of gold per annum for the first 12 years. The Kibali gold mine is located within the Moto greenstone belt. The gold mineralisation is scattered throughout the region. Kibali is co-owned by AngloGold Ashanti (45%), Barrick Gold Corporation (45%) following its merger with Randgold Resources, and Société Minière de Kilo-Moto (SOKIMO) (10%), a state-owned gold mining company. Kibali produced 807,000 ounces of gold in 2018. It comprises an integrated open pit and an underground operation as well as a 7.2Mtpa processing plant. The mine is named for the nearby Kibali River. There are two zones: Kibali-Durba-Karagba trends north-east, and Pakaka-Mengu trends north-west. Gold-bearing deposits are found throughout the region. Facilities include a sulphide and oxide plant that can process 7.2 million tonnes of ore per year, three 44MW hydroelectric stations, a 32MW backup thermal power generator and separate storage facilities for cyanide and flotation tailings.

6.Cadia East, Australia. 195 koz.

Cadia produces gold doré from a gravity circuit and gold-rich copper concentrates from a flotation circuit at Cadia. The gold dore is then refined at the Perth Mint and concentrates are piped to a dewatering plant at nearby Blayney and sent by rail to Port Kembla in New South Wales for export. The Molybdenum Plant is expected to deliver an additional revenue stream in the form of a molybdenum concentrate which will be a by-product credit to AISC per ounce. Newcrest’s Cadia is made up of the Cadia East underground panel cave mine and the Ridgeway underground mine (currently in care and maintenance). Cadia East mine in the Cadia valley produced 752,000 ounces of gold in 2018.
Cadia East is the biggest gold mine in Australia despite 11% production decline in March Quarter 2020. The Cadia East orebody is one of the world’s largest gold deposits, comprising a Mineral Resource of 2,347Mt containing 33.2Moz of gold and 6.59Mt of copper, along with a current Ore Reserve of 18.7Moz of gold and 3.16Mt of copper. It will underpin production from the Cadia Valley for at least the next 30 years. Initial exploration pointed to an underground mine similar to Ridgeway Deeps, however, more recent drilling has revealed that a much larger zone of mineralisation exists, likely to support both underground and open cut mines.

  1. Lihir, PNG. 187 koz.

Newcrest’s Lihir operation on Aniolam Island in the New Ireland Province of Papua New Guinea is 900 kilometres north-east of the capital Port Moresby. The gold deposit at Lihir is within the Luise Caldera, an extinct volcanic crater that is geothermally active.
The Lihir mine produced 976,000 ounces of gold in 2018, a 6% improvement over 2017. Most of the ore extracted from Lihir is treated through pressure oxidation and conventional leaching. The mine produced 933,000oz of gold in the financial year ending June 2019. The mine is expected to produce 1Moz of gold in 2020. Lihir is looking to stabilise throughput at or slightly above these levels and increase focus on lifting recovery rates to maximise overall gold production and cash flow in the future. It employs approximately 4,500 residential and fly-in-fly-out workers.

  1. Loulo-Gounkoto, Mali. 176 koz.

Barrick’s Loulo-Gounkoto complex comprises two distinct mining permits, Loulo and Gounkoto, and is situated in western Mali, bordering Senegal and adjacent to the Falémé River. Barrick Gold Corporation’s Loulo-Gounkoto complex has demonstrated its mettle, exceeding its 2019 guidance with production of 714,802 ounces of gold. An intensive exploration program in the Kenieba region, Loulo-Gounkoto has significant growth potential and is well-placed to meet all the targets. Société des Mines de Loulo SA (Loulo) owns the Loulo gold mine, and Société des Mines de Gounkoto (Gounkoto) owns the Gounkoto gold mine. Both Loulo and Gounkoto are owned by Barrick (80%), and the State of Mali (20%). This is also the product of a long and constructive partnership between the government of Mali and ourselves, and in this regard it is gratifying to report that we have made significant progress towards settling the dispute between us over tax and related issues which allows us to look forward to continuing to grow our partnership with the Mali government and its people

  1. Fekola, Mali. 164 koz.

The Fekola Mine is located in southwest Mali, on the border between Mali and Senegal, approximately 500 km due west of the capital city, Bamako. B2Gold acquired the world-class Fekola Gold Project through a merger with Papillon Resources Limited in October 2014. The Fekola Mine generated almost US$134 million in revenue for the Government of Mali in 2019. B2Gold will continue to monitor the situation and work to ensure that its mining operations continue normally, providing economic benefits and job creation both to the communities around the mine and to regional and national governments. Foreign investment and political stability in Mali are crucial for the country. B2Gold is a low-cost international senior gold producer headquartered in Vancouver, Canada. Founded in 2007, today, B2Gold has operating gold mines in Mali, Namibia and the Philippines, and numerous exploration and development projects in various countries including Mali and Colombia. In 2020, B2Gold forecasts consolidated gold production of between 1,000,000 and 1,055,000 ounces.

  1. Fosterville, Australia. 160 koz.

Kirkland Lake’s Fosterville Mine is second highest-grade and one of the lowest-cost gold mine globally, located 20km from the city of Bendigo in the State of Victoria, Australia. The Fosterville Mine features growing gold production at increasingly high grades, as well as extensive in-mine and district scale exploration potential. In March Quarter 2020, Kirkland Lake achieved 25% y-o-y production growth at Fosterville. In particular, the Swan Zone contributed 532,000 ounces at an average grade of 58.8 g/t Au (281,000 tonnes) to the updated Mineral Reserve estimate. The mine is located in an area with well-developed infrastructure and is accessible by paved roads. Fosterville’s ore is processed at the Fosterville Mill, a 2,275 tonne per day processing facility.

LARGEST 10 GREAT ECONOMIES IN THE WORLD AND THE SOURCES OF ECONOMY

Economy means the state of a country or region in terms of the production and consumption of goods and services and the supply of money. Economies determine how resources are distributed among members of a society, they determine the value of goods or services. The political and legal structure of a society will govern how wealth can be accumulated, how wealth and resources are distributed, and the manner of competition permitted between different participants in the economy. There are three big economic systems in use by modern governments: capitalism, socialism, and communism. We wanted to understand how the top 10 largest economies in the world measured by GDP(Gross Domestic Product). We took historical GDP figures from the International Monetary Fund (IMF) in 2020.

1.United States

The U.S. has retained its position of being the world’s largest economy since 1871. economy of the United States is that of a highly developed country with a mixed economy. It is the world’s largest economy by nominal GDP and net wealth. U.S. Nominal GDP: $21.44 trillion – U.S. GDP (PPP): $21.44 trillion.
The size of the U.S. economy was at $20.58 trillion in 2018 in nominal terms and is expected to reach $22.32 trillion in 2020. The U.S. is often dubbed as an economic superpower and that’s because the economy constitutes almost a quarter of the global economy, backed by advanced infrastructure, technology, and an abundance of natural resources.
When the economies are assessed in terms of purchasing power parity, the U.S. loses its top spot to its close competitor China. In 2019, the U.S. economy, in terms of GDP (PPP), was at $21.44 trillion, while the Chinese economy was measured at $27.31 trillion. United States has the most technologically powerful economy in the world and its firms are at or near the forefront in technological advances, especially in computers, pharmaceuticals, and medical, aerospace, and military equipment. The largest U.S. trading partners are China, Canada, Mexico, Japan, Germany, South Korea, United Kingdom, France, India, and Taiwan. The nation’s economy is fueled by abundant natural resources, a well-developed infrastructure, and high productivity. It is the world’s largest producer of petroleum and natural gas. U.S. not only has the largest internal market for goods, but also dominates the trade in services.

2.China

China Nominal GDP: $14.14 trillion – China GDP (PPP): $27.31 trillion
China has experienced exponential growth over the past few decades, breaking the barriers of a centrally-planned closed economy to evolve into a manufacturing and exporting hub of the world. China is often referred to as the “world’s factory,” given its huge manufacturing and export base. However, over the years, the role of services has gradually increased and that of manufacturing as a contributor to GDP has declined relatively. The IMF projects a growth of 5.8% in 2020.

The economy of India is characterised as a developing market economy. India was the world’s fastest growing major economy and Historically it is the largest economy in the world. The long-term growth perspective of the Indian economy remains positive due to its young population and corresponding low dependency ratio, healthy savings and investment rates, and is increasing integration into the global economy. Apart from private consumption, India’s GDP is also fueled by government spending, investment, and exports. India has one of the world’s highest number of billionaires and extreme income inequality.
According to World Bank, to achieve sustainable economic development India must focus on public sector reform, infrastructure, agricultural and rural development, removal of land and labour regulations, financial inclusion, spur private investment and exports, education and public health. India’s ten largest trading partners were USA, China, UAE, Saudi Arabia, Hong Kong, Iraq, Singapore, Germany, South Korea and Switzerland. India ranks second globally in food and agricultural production. India’s telecommunication industry is the world’s second largest by number of mobile phone, smartphone, and internet users. It is the world’s tenth-largest oil producer and the third-largest oil consumer.

  1. Japan ( $5.89T )

The economy of Japan is a highly developed free-market economy. With this low growth rate, the national debt of Japan has expanded due to its considerable social welfare spending in an aging society with a shrinking tax-base. The scenario of “Abandoned homes” continues to spread from rural areas to urban areas in Japan.
A mountainous, volcanic island country, Japan has inadequate natural resources to support its growing economy and large population, and therefore exports goods in which it has a comparative advantage such as engineering-oriented, research and development-led industrial products in exchange for the import of raw materials and petroleum. The nation’s large and varied forest resources, which covered 70 percent of the country. Japan is among the top-three importers for agricultural products in the world in total volume for covering of its own domestic agricultural consumption. The nation, therefore, built up the manufacturing and processing industries to convert raw materials imported from abroad.
Japan is the world’s largest single national importer of fish and fishery products. This strategy of economic development necessitated the establishment of a strong economic infrastructure to provide the needed energy, transportation, communications, and technology. Tokyo Metropolitan Central Wholesale Market is the largest wholesale market for primary products in Japan. Although many kinds of minerals were extracted throughout the country, most mineral resources had to be imported in the postwar era. Iron ore, copper, bauxite, and alumina must be imported, as well as many forest products. Local deposits of metal-bearing ores were difficult to process because they were low grade. Deposits of gold, magnesium, and silver meet current industrial demands, but Japan is dependent on foreign sources for many of the minerals essential to modern industry. Japan lags behind other developed countries in labor productivity. Early European visitors were amazed by the quality of Japanese craftsmanship and metalsmithing. This stems from the fact that Japan itself is rather rich in natural resources found commonly in Europe, especially iron.

  1. Germany ( $4.59T )

It has the largest national economy in Europe. The economy of Germany is a highly developed social market economy. The top 10 exports of Germany are vehicles, machinery, chemical goods, electronic products, electrical equipment, pharmaceuticals, transport equipment, basic metals, food products, and rubber and plastics. The economy of Germany is the largest manufacturing economy in Europe and it is less likely to be affected by the financial downturn and conduct applied research with practical industrial value and sees itself as a bridge between the latest university insights and industry-specific product and process improvements, and by generating a great deal of knowledge in its own laboratories as well. Germany is rich in timber, lignite, potash and salt. Some minor sources of natural gas are being exploited in the state of Lower Saxony. Until reunification, the German Democratic Republic mined for uranium in the Ore Mountains.
Energy in Germany is sourced predominantly by fossil fuels (30%), followed by wind second, then nuclear power, gas, solar, biomass and hydro. Germany is the first major industrialized nation to commit to the renewable energy transition called Energiewende. Germany is the leading producer of wind turbines in the world. Germany is the world’s top location for trade fairs. Around two thirds of the world’s leading trade fairs take place in Germany. Over time, other German states joined the customs union and started linking their railroads, which began to connect the corners of Germany together. The growth of free trade and of a rail system across Germany intensified economic development which opened up new markets for local products, created a pool of middle managers, increased the demand for engineers, architects and skilled machinists, and stimulated investments in coal and iron.

  1. Russia ( $4.52T )

The economy of Russia is an upper-middle income mixed and transition economy. Russia contains over 30 percent of the world’s natural resources. Russia relies on energy revenues to drive most of its growth. Russia has an abundance of oil, natural gas and precious metals, which make up a major share of Russia’s exports. Russia is considered an “energy superpower”. It has the world’s largest proven natural gas reserves and is the largest exporter of natural gas. Russia has a large and sophisticated arms industry, capable of designing and manufacturing high-tech military equipment, including a fifth-generation fighter jet, nuclear powered submarines, firearms, and short range/long range ballistic missiles. Top military exports from Russia include combat aircraft, air defence systems, ships and submarines. the wealth held offshore by rich Russians is about three times larger than official net foreign reserves, and is comparable in magnitude to total household financial assets held in Russia.
Russia had undergone a radical transformation, moving from a centrally planned economy to a globally integrated market economy. Especially in the production of oil, gas, and electricity and in the chemical industries—there was a marked diversification in industrial output, including a limited expansion in consumer goods. Major components of the reforms included establishing privately owned industrial and commercial ventures and privatizing state-owned enterprises. To encourage privatization, the government issued vouchers to Russian citizens that enabled them to purchase of shares in privatized firms, though in practice these vouchers frequently were sold for cash and were accumulated by entrepreneurs. A commodity- and stock-exchange system also was established. For business growth, taxes on medium and small enterprises were moderated, and the government began to offer incentives for reinvesting profits into the domestic economy. By the early 21st century, the measures had begun to have a positive effect on the Russian economy, which showed signs of recovery and stable growth. Steady earnings from oil exports permitted investments in factories, and the devalued currency made Russian goods more competitive on the international market.

  1. Indonesia ( $4.01T )

Indonesia is a country in Southeast Asia and Oceania, between the Indian and Pacific oceans. It has charted impressive economic growth since overcoming the Asian financial crisis of the late 1990s. The world’s 10th largest economy in terms of purchasing power parity, and a member of the G-20. Furthermore, Indonesia has made enormous gains in poverty reduction, cutting the poverty rate by more than half since 1999, to 9.78% in 2020. It aims to further strengthen Indonesia’s economy by improving the country’s human capital and competitiveness in the global market. The Indonesian economy has been climbing steadily higher. Indonesia is the world’s largest island country .
Indonesia is composed of some 17,500 islands, of which more than 7,000 are uninhabited. It is the 14th-largest country by land area, at 1,904,569 square kilometres (735,358 square miles). The country’s capital, Jakarta, is the second-most populous urban area in the world. In the early 21st century Indonesia was the fourth most populous in the world. The name Indonesia derives from Greek Indos and the word nesos, meaning “Indian islands”. The economy of Indonesia is the largest in Southeast Asia and is one of the emerging market economies of the world. As an upper-middle income country and member of the G20, Indonesia is classified as a newly industrialised country.

  1. Brazil ( $3.60T )

Brazil is one of the world giants of mining, agriculture, and manufacturing, and it has a strong and rapidly growing service sector. The country was heavily dependent on one or two major agricultural products, whose prices fluctuated widely on international markets. The Brazilian government in the 20th century attempted to diversify the country’s production and reduce its dependency on agricultural exports by strongly encouraging manufacturing. The government initiated several key industries, including a modern shipbuilding program, a petrochemical sector led by the huge Petrobras company, a burgeoning microelectronics and personal computer industry, and aircraft manufacturing by the Embraer corporation, including commercial jetliners, aviation and surveillance equipment, and aircraft for the Brazilian air force. It established a motor vehicle industry in the 1950s to replace U.S. and German imports and assembly plants. The government privatized dozens of financial institutions, manufacturers, and mining companies in the 1990s, including several major steel producers and the Rio Doce Valley Company.
The CVRD, Brazil’s giant mining and shipping conglomerate, was apportioned into separate mining and shipping units. The government also sold a minority of its Petrobras shares to private investors and partially opened the petroleum industry to competition. At the beginning of the 21st century, serious problems marked the Brazilian economy, aggravated by political uncertainties. Inflation, financial instability, and unemployment (or underemployment) remained constant threats, and political and financial scandals periodically erupted throughout the country. Brazil still has one of the world’s most lopsided distributions of wealth. It is a leading producer of a host of minerals, including iron ore, tin, bauxite (the ore of aluminum), manganese, gold, quartz, and diamonds and other gems, and it exports vast quantities of steel, automobiles, electronics, and consumer goods. Brazil is the world’s primary source of coffee, oranges, and cassava (manioc) and a major producer of sugar, soy, and beef.

  1. UK ( $3.24T )

The economy of the United Kingdom is a highly developed social market and market-orientated economy. In 2019, the UK was the fifth-largest exporter in the world and the fifth-largest goods importer. It also had the second-largest inward foreign direct investment, and the third-largest outward foreign direct investment. UK is one of the most globalised economies, and it is composed of England, Scotland, Wales and Northern Ireland. The service sector dominates, contributing around 80% of GDP, the financial services industry is particularly important, and London is the second-largest financial centre in the world. The currency of the UK is the pound sterling, which is the world’s fourth-largest reserve currency. The economy of the United Kingdom has slowly been climbing the ranks of the mostly free for the past decade. Although some economic disruptions are likely, the U.K. will also have new opportunities to expand economic freedom, especially by reducing the tax burden and government spending and pursuing new trade agreements with the United States and other countries.
UK economic output shrank by 20.4% in the second quarter of 2020, the worst quarterly slump on record, pushing the country into the deepest recession of any major global economy. Britain already faces a tough 2021 as the country battles the twin shocks of coronavirus and Brexit. But failing to secure an agreement with the United Kingdom’s biggest export market would amplify the pain. With a limited trade agreement, the UK economy is due to bounce back with growth of 4.6% in 2021 before losing some momentum between 2022 and 2024, according to IFS and Citi projections. Failing to reach a trade deal with Europe would shave as much as one percentage point off that level of growth.

10.France ($3.16T )

The economy of France is highly developed and free-market-oriented. France is one of the major economic powers of the world, ranking along with such countries as the United States, Japan, Germany, Italy, and the United Kingdom. It included the large industrial companies such as Renault. France is also the most visited destination in the world, as well the European Union’s leading agricultural power. France IS the largest Foreign Direct Investment recipient in Europe in 2020. Paris is a leading global city and it has one of the largest city GPD in the world. Paris has been ranked as the 2nd most attractive global city in the world in 2019 by KPMG. 31 companies that are part of the world’s biggest 500 companies are existing here. It is the world’s fourth largest private oil company.
Another indicator of improved living standards is the growth of ownership of various household and consumer goods, particularly such items as automobiles and computers. Here indirect taxation in the form of a value-added tax (VAT) is relatively high. The top individual income tax rate is 45 percent, and the top corporate tax rate is 31 percent. Other taxes include a value-added tax. The overall tax burden equals 46.2 percent of total domestic income. The overall managerial environment is bolstered by France’s modern business culture, mature financial markets, skilled entrepreneurs, and well-protected intellectual property rights. The total value of exports and imports of goods and services equals 63.4 percent of GDP. State ownership is primarily concentrated in transport, defense, and broadcasting.

LARGEST 10 GREAT HYDROELECTRIC DAMS IN THE WORLD IN TERMS OF INSTALLED POWER

A hydroelectric dam is one of the major components of a hydroelectric facility. A dam is a large, man-made structure built to contain some body of water. In addition to construction for the purpose of producing hydroelectric power, dams are created to control river flow and regulate flooding. In some rivers, small scale dams known as weirs are built to control and measure water flow. Dams fall into the category of retaining structures, or structures that are built to create large standing bodies of water known as reservoirs. These reservoirs can be used for irrigation, electrical generation, or water supply. Hydroelectricity is one of the fore-runners of the renewable energy industry. Here are 10 Largest hydroelectric Dams in the World in terms of installed power.

1.Three Gorges Dam, China

The Three Gorges Dam has been the world’s largest power station in terms of installed capacity (22,500 MW) since 2012. In 2018, the dam generated 101.6 terawatt-hours (TWh). As well as producing electricity, the dam is intended to increase the Yangtze River’s shipping capacity. The dam is located 44km from the city of Yichang in Hubei province. The project has 34 generators, which includes 32 main generators. The other two are power generators with a capacity of 50MW each. When construction of the dam officially began in 1994, it was the largest engineering project in China. At the time of its completion in 2006, it was the largest dam structure in the world. The height of Three Gorges is about 594 feet (181 meters (m)) and the length is about 7,770 feet (2, 335 m).
The dam creates the Three Gorges Reservoir, which has a surface area of about 400 square miles (1,045 square kilometers) and extends upstream from the dam about 370 miles (600 kilometers). The gorge controls approximately one million square kilometres of drainage area and averages a runoff of 451 billion cubic metres annually. Ecology and environmental monitoring information system for the project was opened in 2007. Fish Nurturing Centre Base was also built for the conservation of Asian carp and other species through the eco-scheduling process. The official total cost of the Three Gorges Dam project was estimated as CNY203bn ($29bn).

2.Itaipu Dam, Brazil and Paraguay

The Itaipu Dam is a hydroelectric dam on the Parana River located on the border between Brazil and Paraguay. The volume of this Dam is 12,300,000 m3 (430,000,000 cu ft) and total capacity is 29 km3 (24,000,000 acre⋅ft). It’s location is Foz do Iguacu, ‎Hernandarias. Itaipu Hydroelectric Dam is the world’s second-largest operational hydroelectric power plant in terms of installed power. With an installed generation capacity of 14GW, the plant is operated by Itaipu Binacional and located on the border between Brazil and Paraguay. Energy generated by Itaipu helps to meet the demands of the two countries. Approximately 90% of the energy generated by the plant is used by Brazil. Itaipu has 20 generating units, each with a capacity of 700MW. The dam’s reservoir, which covers an area of 1,350km² with Spanning of 170 kilometers in length.
The name “Itaipu” was taken from an isle that existed near the construction site. In the Guarani language, Itaipu means “the sounding stone”. To ensure water quantity and quality, Itaipu has created an environmental conservation area, planting more than 44 million trees. The protected areas now total over 100,000 hectares, including reserves and wildlife refuges in both countries and the biological forest corridor that protects the reservoir.Recently, Itaipu became the first hydroelectric plant in the world to have its own protected areas and supporting landscapes which are now recognized by UNESCO as a Biosphere Reserve. Although forest conservation is an essential safety measure for water security, it also depends on other environmental priorities, especially those that relate to land use. It regularly surpasses the production of the larger dam and holds the world record for energy produced, achieving 103.1 terawatt-hours (TWh) in 2016.

3.Xiluodu Dam, China

The Xiluodu Dam is an arch dam on the Jinsha River, i.e. the upper course of the Yangtze in China. It is located near the town of Xiluodu in Yongshan County of Yunnan Province but the dam straddles into Leibo County . The primary purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 13,860 MW. The primary purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 13,860 MW. Additionally, the dam provides for flood control, silt control and its regulated water releases are intended to improve navigation downstream. Xiluodu power plant offsets approximately 150m tonnes of carbon dioxide emissions a year. It reduces the consumption of 41 million tonnes of coal for electricity generation. The Xiluodu plant generates 64bkWh of electricity a year.
The Xiluodu plant is made up of two power houses located on both sides of the dam. The power house comprises 18 Francis turbine-generators and an air-cooled generator with 855.6MVA output. The reservoir has a total storage capacity of 16.5 billion cubic yards, of which six billion cubic yards are for flood control. The construction of the dam was carried out using belt conveyors, crawler tractors, hydraulic excavators, rock trucks and wheel loaders. The water discharge structures of Xiluodu Hydropower Station are composed of 7 surface holes of the dam body, 8 deep holes and 4 spillway tunnels on the bank. The main task of flood control operation of Xiluodu Hydropower Station is to control the flood of the Chuanjiang River section and enhance the flood control standard of cities such as Yibin along the bank, while ensuring the safety of the hydro-complex project.

4.Guri Dam, Venezuela

The Guri power project, also known as the Simon Bolivar hydroelectric power station, is located on the Caroni River in the Bolivar State of southeastern Venezuela. Installed Capacity is 10,235 MW. The power plant consists of 20 generating units of different capacities ranging between 130MW and 770MW. Surface Area of this dam is 4,250 km2 (1,641 sq mi). The Guri dam measures 532ft in height and 4,314ft in length. To free a greater proportion of the country’s petroleum for sale and export, the Venezuelan government made the bold move to transition from hydrocarbon- to hydroelectric-generated power as the country’s primary electricity source. The economic efficiency of Guri Dam’s construction can be attributed to its phased development. While other concepts called for the dam to be built to the final height at the first stage a much easier design the region would not have been able to absorb all of the generated power, making it more difficult to finance.
In addition, the compact and incremental design of the dam resulted in inexpensive power at the time approximately US$550 per kW, which attracted aluminum and iron ore smelting industries to the area. Fulfilled government’s goal to significantly decrease dependence on petroleum as a domestic power source: ability to generate more than 10,000MW and produce up to 50,000GWh per year—the equivalent of 300,000 barrels of oil per day. Alstom was awarded two contracts in 2007 and 2009 to refurbish four 400MW units and five 630MW respectively. Andritz received a contract to supply five 770MW Francis turbines for the powerhouse II of Guri in 2007. The Guri power station supplies approximately 12,900GW/h of energy for Venezuela. The plant provides approximately 50,000GW/h of energy to the country annually.

5.Belo Monte Dam, Brazil

The Belo Monte power station is owned and operated by Norte Energia. The Belo Monte hydropower project under construction on the lower reach of the Xingu River, in Para, Brazil, was installed with 9.39GW generating capacity as of September 2019. The project comprises two dams and two powerhouses, including a main powerhouse equipped with 18 Francis turbines of 611MW capacity each, and a supplemental power house with six 38.85 MW Bulb turbines. The capacity of the dam is 11,233 megawatts (MW). This Dam is the second largest hydroelectric dam in Brazil. Brazil’s rapid economic growth over the last decade has provoked a huge demand for new and stable sources of energy, especially to supply its growing industries. In Brazil, hydroelectric power plants produce over 85% of the electrical energy. The aim is to stimulate the country’s economic growth by building a huge infrastructure of roads and dams, mainly in the Amazon region. The controversial Belo Monte mega-dam in Para state has done significant socio environmental harm to the Xingu River and the indigenous and traditional people living beside it.
Important Brazilian Panel on Climate Change report warned that global warming could drop water levels all across the Amazon basin, putting hydropower in serious jeopardy. Brazil needs Belo Monte and 60 other major dam projects in the Amazon to meet its growing energy demand. Belo Monte’s 668km2 reservoir will flood over 400km2 of forest, generating enormous qualities methane, a greenhouse gas that is 25 times more potent than CO2. Like other big dams, Belo Monte would cause considerable direct and indirect environmental destruction. Belo Monte is only one dam complex, not a series of upstream dams. The government is aware that Belo Monte’s seasonal inefficiency can only be managed by creating more dam reservoirs upstream, allowing technicians to regulate river flows for the entire year. As such, project plans continue to point to the eventual construction of four dams in addition to Belo Monte: Altamira, Iriri, Pombal, and Sao Felix.

6.Tucurui Dam, Brazil

A more modest hydroelectric facility on a small river north of Manaus supplies that city with power. The Tucuruí Hydropower Complex situated on the lower Tocantins River in Tucurui, Para, Brazil. It involved installation of 11 generating units with 370MW capacity each. It is the first large-scale hydroelectric project in the Brazilian Amazon rainforest. The installed capacity of the 25-unit plant is 8,370 megawatts (11,220,000 hp). The power station delivers electricity to the Belem town and the surrounding area. It is located about 350 kilometers from the state’s capital Belém, it caused the flooding of an area of about 3,014 km2 and displaced about 32,000 people. A case study on the social impacts of the Tucuruí dam by Fearnside (1999) reported a systematic overestimation of the plant’s benefits by public authorities, while social and environmental impacts have rather been downplayed, making it an example of Brazil’s unlearned lessons in hydroelectric development.
It notes that most generated power was used for the highly subsidized aluminum industry in Barcarena and Sao Luis. Additionally, dams disturb the flow and composition of the water within rivers and channels. Water released downstream from dams has unnaturally high energy and very little sediment, which causes “hungry water” to run forcefully, eroding the riverbeds, without sufficient sediment concentration to slow it down. This deepens the riverbed compared to the surrounding water table, which causes the ground water to rush into the channel and become surface water – a process known as incision.

7.Grand Coulee Dam, USA

The Grand Coulee hydropower project located on the Columbia River in Washington, US. The annual generating capacity of the plant is more than 24TWh. It consists of total 18 Francis turbines rated 125MW and three 10MW additional units. The Grand Coulee is an ancient river bed in the U.S. state. This area has underlying granite bedrock, formed deep in the Earth’s crust 40 to 60 million years ago. The land periodically uplifted and subsided over millions of years giving rise to some small mountains and, eventually, an inland sea. The dam has four power plants. It is 550 feet (167.6 meters) tall, measured from its foundation in solid granite, or approximately 350 feet (106.7 meters) from the downstream river surface to the top of the dam. It is 5,223 feet (1,592 meters) long, or 57 feet short of a mile. The two original power plants. The total generating capacity is 6,809 megawatts and its average annual energy output is about 2,300 megawatts, or enough power to continuously supply the needs of two cities the size of Seattle.
Hydropower accounts for 79.7 percent of Grand Coulee’s authorized purposes, the others being irrigation and flood control. While hydropower is the primary purpose of the dam today, the public desire for irrigation was the driving force behind its construction. Hydroelectric power plants provide a very efficient, renewable method of generating electricity without producing air pollution. Hydroelectricity produced electricity currently accounts for nearly 7% of the total electricity generated in the United States. However, currently less than 3% of all dams in the United States are used to generate electricity. This discrepancy presents a great opportunity to increase the use of renewable energy production through hydroelectric power. There are many factors which make hydroelectric energy a desirable alternative to the burning of fossil fuels, yet the construction and operation of hydroelectric plants also involves a number of disadvantages. These drawbacks include environmental changes which could adversely affect the health of humans and animals.

8.Xiangjiaba, China

Xiangjiaba is built on the outlet of Jinsha River canyon, which is located Yibin City of Sichuan and Shuifu County, Yunnan, China. The reservoir area is 458,800km² and the reservoir capacity is 5.163 billion cubic metres. The power plant is installed with eight units of 800MW each and comprises various structures for flood discharge, diversion, power generation, and ship lift. The Xiangjiaba is gravity dam with 162m-high and has a crest elevation of 384m. The annual generating capacity of the power plant is 30.88kWh. The Xiangjiaba hydropower facility exploits the lower mainstream water of Jinsha River, a tributary of the Yangtze River. After the successful launch of the Three Gorges hydro power project in 1994, the CTG was authorised for building four hydropower plants namely Xiluodu, Xiangjiaba, Wudongde and Baihetan, all located either on the mainstream or on the tributaries of the Yangtze River. The power output of the Xiangjiaba hydroelectric plant is supplied to central China and east China via the 800kV Xiangjiaba-Shanghai UHVDC (Ultra High Voltage Direct Current) transmission link.
Xiangjiaba will be the third largest hydropower project in the country, after Three Gorges and Xiluodu. As an important part of China’s Great Western Development Programme, the project is expected to drive local social and economic development. It will primarily supply power to China’s central and eastern regions, while at the same time meeting power demand in the Sichuan and Yunnan provinces. The project Xiangjiaba hydro project includes eight turbine generator sets. Major benefits are from power generation to CO2 reduction and flood control. The Xiangjiaba hydropower project brings major flood control benefits, and its combined operation with the Xiluodu hydropower project will improve flood prevention in the downstream coastal cities of Yibin, Luzhou and Chongqing.

9.Sayano-Shushenskaya, Russia

The Sayano-Shushenskaya hydropower plant located on the Yenisei River in Sayanogorsk, Khakassia, Russia. It is operated by RusHydro. An arch-gravity dam 242m tall and 1,066m long was constructed as part of the project. The power plant consists of ten Francis generating units with a capacity of 640MW each. It generates 23.5TWh of energy a year, of which 70% is delivered to four aluminium smelters in Siberia. It is the largest power plant in Russia and the 9th-largest hydroelectric plant in the world, by average power generation. Plant operated ten hydro turbines manufactured at the Leningradsky Metallichesky Zavod, each of which at 194-metre (636 ft) head. The destruction of the turbines and auxiliary equipment at Russia’s Sayano-Shushenskaya Hydro Power Plant in August 2009 claimed the lives of 75 workers and wrecked an indispensable source of electricity that will take years to fully restore.
The disaster, as this report explains, was predictable and preventable. technicians were operating multiple hydroelectric turbines at the plant, including Unit 2, and plant maintenance work on other equipment was continuing. About 70% of the energy generated by RusHydro goes to United Company Rusal’s aluminum smelters, which produce about 12% of the world’s aluminum. It consists of a solid left-bank dam 246.1 metres long, a power dam 331.8 metres long, a spillway dam 189.6 metres long and a solid right-bank dam 298.5 metres long. The dam supports the Sayano-Shushenskoe reservoir, with a total capacity of 31.34 km3, useful capacity of 15.34 km3 and surface area of 621 km2.

10.Longtan Dam, China

The Longtan hydropower project located on the Hongshui River in Tian’e County, Guangxi, China, is the sixth biggest in Asia. The hydroelectric power station consists of nine Francis 700MW generating units. The Longtan dam is a roller-compacted concrete gravity dam 216.5m in height and 832m in width. The dam is intended for hydroelectric power production, flood control and navigation. The dam contains seven surface spillways, two bottom outlets and an underground power station. This gravity dam more than 700 feet tall, So this is the tallest of its type in the world. The hydroelectric power station consists of 9 power generating units with a capacity of more than 17.3 billion kilowatt hours. This system of valves provides a high quality, reliable solution to the stringent requirements of one of the largest and most advanced hydroelectric generation plants of its kind, ensuring optimal utilization of available natural resources. The project is owned by Longtan Hydropower Development. The dam’s newest hydroelectric turbine was installed in 2009. The design and construction of the dam have applied the state of the art of modern RCC and it also represents the highest level of present RCC construction. After reservoir impoundment, the dam’s operation is normal and presents good performance.

THE GREAT 10 FRESH WATER LAKES IN THE WORLD BY SURFACE AREA

Freshwater lakes are bodies of still, unsalted water surrounded by land. They are usually found in low lying areas and are fed from streams, rivers and runoff from the surrounding area. Lake, any relatively large body of slowly moving or standing water that occupies an inland basin of appreciable size. Definitions that precisely distinguish lakes, ponds, swamps, and even rivers and other bodies of non oceanic water are not well established. Fresh water can be defined as water with less than 500 parts per million (ppm) of dissolved salts. Water is critical to the survival of all living organisms. 3% of the earth’s water is fresh. 2.5% of the earth’s fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth’s surface to be extracted at an affordable cost. 0.5% of the earth’s water is available fresh water. Here are the top 10 largest freshwater lakes by Surface Area in the world.

1.Lake Superior

Lake Superior is the Largest fresh water lake by surface area. It has taken into the account of the saline Caspian sea. Lake Superior has been described as “the most oligotrophic lake in the world.” It is also the second largest lake in the world. It is shared by the USA and Canada, also the part of the Great Lakes of North America. Lake Superion occupies an area of 82,400 square kilometers. These magnificent freshwater lakes are not only beautiful, but also essential for human survival. Lake Superior is home to 88 species of fish. Lake Superior contains 10% of all the earth’s fresh surface water. The deepest point in Lake Superior (about 40 miles north of Munising, Michigan) is 1,300 feet (400 meters) below the surface. Lake Superior has over 400 islands, the largest of which is Isle Royale, with a size of 207 square miles. The lake has an island called the Isle Royal, which contains many smaller lakes, which in turn have their own islands as well. The Lake Superior shoreline, if straightened out, could connect Duluth and the Bahama Islands.
The average underwater visibility of Lake Superior is 27 feet, making it easily the cleanest and clearest of the Great Lakes. Underwater visibility in places reaches 100 feet. The lake is home to many endemic species of fish, however, some have been wiped out due to overfishing and exotic species being introduced. The lake’s primary inflows are the Nipigon River, the St. Louis River, the Pigeon River, the Pic River, the White River, the Michipicoten River and the Kaministiquia River. The only outflow of Lake Superior is the St. Mary’s River. We must srtive to protect these from further degredation, for our sake, and for the sake of their intrinsic value. Water in Lake Superior is retained, on average, 191 years. Migrating birds of prey funnel down Lake Superior’s north shore in great numbers each fall. On a single day at Duluth’s Hawk Ridge as many as 100,000 birds of prey might pass by. Lake Superior rests mostly on Precambrian rock at the southern edge of the Canadian shield, the largest exposure of such bedrock on the planet.

2.Lake Victoria

Lake Victoria is the world’s largest tropical lake and the second largest freshwater lake. It has 69,485 square kilometres area and is shared by Kenya, Uganda and Tanzania. It covers with a maximum depth of 80 m it is relatively shallow. A population of over 30 million people live in its basin. Lake Victoria is one of the African Great Lakes and is named after Queen Victoria. There are 84 islands inside the lake itself. In Lake Victoria the water hyacinth caused a reduction in fish through de-oxygenation of water, blocking of the in flow and out-flow of the lake, and disruption in fishing activities and lake transportation in late 1990s. Water hyacinth is a fresh water plant capable of vigorous growth. It was introduced on the African continent as an ornamental plant in early 20th century, and since then has spread rampantly. This massive lake, commonly known as Nyanza, is twice the size of Wales, and forms a natural boundary between Kenya, Tanzania and Uganda. The lake is the heart of the African continent, the source of its mightiest river, the Nile.
This mighty body of water is rich in fish life, with shimmering shoals of colourful cichlids and large Nile Perch. The ecological health of Lake Victoria has been affected profoundly as a result of a rapidly growing population, clearance of natural vegetation along the shores, a booming fish-export industry, the introduction of several exotic plant and animal species, the disappearance of about 50 % of its fish species, prolific growth of algae, and dumping of untreated effluent by several industries and human settlements. It has suffered tremendously in terms of biodiversity due to the introduction of new exotic species and water pollution. As a result, the fishing industry of the area has also suffered. The lake receives water from annual rainfall, as it lies in the tropical regions. Lake Kagera is also one of the sources of water. The lake’s outflow is the river Nile, which is most famous.

3.Lake Huron

West of Lake Michigan is Lake Huron, which is shared between USA and Canada. The lake reaches a maximum depth of 750 ft. It has a surface area of 59,600 square kilometres but has lower volumes of water than Lake Michigan. The name of the lake is derived from early French explorers who named it for the Huron people inhabiting the region. The Huronian glaciation was named due to evidence collected from Lake Huron region. The northern parts of the lake include the North Channel and Georgian Bay. Lake Huron was originally called La Mer Douce, or “the freshwater sea,” by French explorers. It has the longest shoreline of the Great Lakes. Mackinac Island is a popular tourist attraction. It is home to the Manitoulin Island, which is the largest island to be found in any lake throughout the world.
Lumbering and fishing have been important economic activities in the Lake Huron region, and many resorts line the lake’s shores. The Saginaw River basin is intensively farmed and contains the Flint and Saginaw-Bay City metropolitan areas. The lake was once home to a number of fish and other species of animals, but this has suffered due to the introduction of exotic and invasive species post colonisation. As part of the St. Lawrence Seaway, the lake supports heavy commercial traffic in iron ore, grain, and limestone. The primary inflows of the glacial lake are the Straits of Mackinac, the St. Marys River. The main outflow of this river is the St. Claire River. The lake is 206 mi (331 km) long from northwest to southeast, and its maximum width is 183 mi.

4.Lake Michigan

Lake Michigan is one of the five Great Lakes of North America. Lake Michigan is the only one of the Great Lakes located entirely within one country, the United States. Dipping the toes into the freshwater and watching a Pure Michigan sunset will become a great experience in the life. It is shared, from west to east, by the states of Wisconsin, Illinois, Indiana, and Michigan. Green Bay is a large bay in its northwest and Grand Traverse Bay is in the northeast. Michigan’s western Great Lakes region benefits from a unique climate, which creates a favorable environment for growing a wealth of agricultural products. The word “Michigan” is believed to come from the Ojibwe word Michi Gami meaning “large lake”. This lake is with a water surface area of 22,300 square miles. The lake also contains numerous islands, notably the Beaver Island archipelago and the North and South Manitou Islands located between the Upper and Lower peninsulas. Approximately 100 streams flow into the lake, only a few of which are of appreciable size. The Manistee, Pere Marquette, White, Muskegon, Grand, Kalamazoo, and St. Joseph rivers enter the lake from the east.
There are 59 lighthouses that stand on the beaches of Lake Michigan as reminders of the importance of the centuries-old shipping industry, a story told well at the Michigan Maritime Museum in South Haven. The state is a leader in many crops including blueberries, cherries, asparagus and grapes for juice and wine. Approximately 12 million people live along the shores of Lake Michigan. There are a number of beaches along the coast, and the Great Lakes are sometimes referred to as the “Third Coast” behind the Pacific and Atlantic. Some of the most popular “beach” towns on the Michigan side of the lake include St. Joseph, South Haven, Grand Haven and Holland. The water of Lake Michigan has an unusual circulatory pattern. Winds and resulting waves keep Lake Michigan from freezing over, but it has been 90 percent frozen on a number of occasions. The lake’s average water depth is 279 feet (85 meters) and its maximum depth is 925 feet (282 meters).

5.Lake Tanganyika

Lake Tanganyika is an African Great Lake With a maximum depth of 1470 m and an area of 32 900 km². Its volume of 18 880 km³ It is the second-oldest freshwater lake in the world, the second-largest by volume. It is the deepest lake in Africa and holds the greatest volume of fresh water, accounting for 16% of the world’s available fresh water. Tanganyika is considered one of the most biologically rich lakes on the planet. According to the World Conservation Union (IUCN), “no place on earth holds such a variety of life.” Of the 2000 plus species found in the lake, over half are found nowhere else. At least 90% of the water influx is from rain falling on the lake’s surface and at least 90% of the water loss is from direct evaporation. The clear waters host more than 350 different species of fish and is well known for aquarium fish exports and excellent angling. The major river flowing into the lake is the Ruzizi River, formed about 10,000 years ago, which enters the north of the lake from Lake Kivu. Lake Tanganyika has a remarkably uniform temperature. The lower regions are only a mere 3° C colder than the surface.
The reason for this strange phenomenon has yet to be discovered. The lake has a complex history of changing flow patterns, due to its high altitude, great depth, slow rate of refill, and mountainous location in a turbulently volcanic area that has undergone climate changes. Lake Tanganyika is an ancient lake. Its three basins, which in periods with much lower water levels were separate lakes, are of different ages. It’s water tend to be brackish. Though fed by a number of rivers, the lake is not the centre of an extensive drainage area. The largest rivers discharging into the lake are the Malagarasi, the Ruzizi, and the Kalambo, which has one of the highest waterfalls in the world (704 feet [215 metres]). Lake Tanganyika is also an evolutionary showcase due to its great age and stability. Ninety eight percent of the lake’s cychlids (which comprise two thirds of all the lake’s fish) are unique to Tanganyika. Also endemic are all seven of its crabs, five out of the thirteen bivalve molluscs, more than half of its gastropod molluscs and eleven of its thirty three copepod crustaceans. Sport fishing is very popular here and catches include the goliath tigerfish and Nile perch.

6.Lake Baikal

Situated in south-east Siberia, the 3.15-million-ha Lake Baikal is the oldest (25 million years) and deepest (1,700 m) lake in the world. It is the largest freshwater lake by volume in the world, containing 22–23% of the world’s fresh surface water With 23,615.39 km3 (5,670 cu mi) of fresh water. It contains more water than the North American Great Lakes combined. With a maximum depth of 1,642 m (5,387 ft) Baikal is the world’s deepest lake. It is considered among the world’s clearest lakes. Baikal is home to thousands of species of plants and animals, many of which are endemic to the region. It is also home to Buryat tribes, residing on the eastern side of the lake, raising goats, camels, cattle, sheep, and horses, where the mean temperature varies from a winter minimum of −19 °C to a summer maximum of 14 °C. Known as the ‘Galapagos of Russia’, its age and isolation have produced one of the world’s richest and most unusual freshwater faunas, which is of exceptional value to evolutionary science. It is home to approximately 1,700 to 1,800 endemic plant and animal species. Lake Baikal has historically played a large role in the Russian imagination.
It represents the unspoiled beauty of Russia and is sometimes referred to as the Sacred Sea. It attracts more than 500,000 tourists a year. The lands around Lake Baikal are generally warmer than the rest of the area because large bodies of water have a moderating force. There are 27 mostly uninhabited islands in Lake Baikal. More than 300 streams and rivers feed into Lake Baikal, but the Angara River is the only outlet. It carries out about 60 cubic km (15.8 trillion gallons) of water per year into the Yenisei River. During the summer, when the lake is full of melted ice from the Siberian mountains, it is sometimes possible to see more than 130 feet (39 m) down. The stunning clarity is the result of the melted ice’s purity, plankton that eat floating debris and a lack of mineral salts in the lake , according to Baikal World Web. There are several theories about what could have caused the unification, including sinking earth, falling rocks, erosion and earthquakes. Likely, it was a combination of all factors. Lake Baikal is in a rift valley and up to 2,000 earthquake tremors are detected each year.

7.Great Bear Lake

Great Bear Lake, lake in northern Fort Smith region and southeastern Inuvik region, Northwest Territories, Canada, lying astride the Arctic Circle. The Great Bear Lake is a lake in the Canadian boreal forest. It is the largest lake entirely in Canada. The fourth-largest in North America, and the seventh-largest in the world. The name originated from the Chipewyan language word satudene, meaning “grizzly bear water people.” The Sahtu Dene people are named after the lake. Grizzly Bear Mountain on the shore of the lake also comes from Chipewyan, meaning, “bear large hill.” Irregular in shape and containing many small islands, Great Bear Lake is roughly 200 miles (320 km) long and 25–110 miles (40–175 km) wide and has a maximum depth of 1,356 feet (413 m). Its area of 12,096 square miles (31,328 square km) makes it the largest lake entirely within Canada and the fourth largest in North America. The 70-mile- (113-kilometre-) long Great Bear River, which drains the lake westward through marshes into the Mackenzie River, forms an important transportation link during its four ice-free months.

8.Lake Malawi

Lake Malawi is an African Great Lake and the southernmost lake in the East African Rift System, located between Malawi, Tanzania and Mozambique. Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique. It is the fourth largest fresh water lake in the world by volume. Lake Malawi is between 560 and 580 kilometers long and about 75 kilometers wide at its widest point. The lake has a total surface area of about 29,600 square kilometers. The lake is 706 m at its deepest point. This is the third largest and second deepest lake in Africa. Lake Malawi is a meromictic lake, meaning that its water layers do not mix. The property is an area of exceptional natural beauty with the rugged landscapes around it contrasting with the remarkably clear waters of the lake. Lake Malawi is globally important for biodiversity conservation due to its outstanding diversity of its fresh water fishes.
The property is considered to be a separate bio-geographical province with estimates of up to 1000 species of fish half occurring within the property, estimated as the largest number of fish species of any lake in the world. Endemism is very high: of particular significance are the cichlid fish, of which all but 5 of over 350 species are endemic. The lake contains 30% of all known cichlids species in the world. The property is also rich in other fauna including mammals, birds and reptiles. There are five villages included within enclaves inside the property. Here the soil is poor and crop failure frequency is high. Collaboration with the governments of Tanzania and Mozambique needs to be maintained and strengthened for the long term protection and management of the entire lake ecosystem, and consideration of the potential for its extension is required.

9.Great Slave Lake

Great Slave Lake is the second-largest lake in the Northwest Territories of Canada. It is also the deepest lake in North America at 614 metres (2,014 ft), and the nineth-largest lake in the world. It covers an area of 28,568 km2 (10,502 sq mi) in the southern part of the territory. The lake shares its name with the First Nations peoples called Slavey of the Dene family by their enemies the Cree. This place gets in our soul. It’s the endless water and endless land. It’s that feeling you get when you take off from civilization with the roar of twin otter engines in your ears – and the freedom you feel once you arrive. Great Slave has been at the heart of history, culture and recreation in the Northwest Territories. Every year some 5,000 trophy fishers come North, many bound for the Great Slave’s North Arm and East Arm. Because the lake is clean and cold, fish keep near the surface in summer. Yellow Knife, the capital of the Northwest Territories, is an isolated mining town built on gold and now sustained by diamonds—an outpost of civilization surrounded by a vast, austere landscape of rock and tundra and water—most notably, the enormous Great Slave Lake, on whose shore the city is built. Yellowknife Bay shelters a fleet of more than two-dozen houseboats, all brightly painted and lovingly adorned. Residents run their floating homes on some combination of solar power and batteries. This pretty, nautical neighbourhood even hosts its own version of a drive-in film festival, albeit with canoes and kayaks. The lake is fed by several rivers, of which the Slave River from the south is the most important, and is drained to the west by the Mackenzie River, which eventually empties into the Arctic Ocean. Many of these communities depend on the lake for its abundance of fish, which helps drive the fishing and tourism industry.

10.Lake Erie

It forms the boundary between Canada (Ontario) to the north and the United States (Michigan, Ohio, Pennsylvania, and New York) to the west, south, and east. It is the southernmost, shallowest, and smallest by volume of the Great Lakes and therefore also has the shortest average water residence time. The major axis of the lake extends from west-southwest to east-northeast for 241 miles (388 km), and the lake has a maximum width of 57 miles. Approximately twelve million people live in the watershed, including seventeen metropolitan areas with more than 50,000 residents. The lake provides drinking water for about eleven million of these inhabitants. At its deepest point Lake Erie is 210 feet (64 metres) deep. The lake was named by the Erie people, a Native American people who lived along its southern shore. The tribal name “erie” is a shortened form of the Iroquoian word erielhonan, meaning long tail. The total area of the lake’s drainage basin is 30,140 square miles (78,062 square km), exclusive of surface area, which is 9,910 square miles.
Numerous new cleanliness and wellness policies and procedures have been put into place throughout the region to ensure that our guests not only have a fun and memorable visit, but a safe one. A place where time moves a little slower, loved ones feel a little closer and there’s a Great Lake between you and your worries. From island hopping to birdwatching, record-breaking roller coasters to water parks, wineries to dockside dining, plus hidden gems that keep the fun going all year long. Algae can persist for weeks during summer by blooms carried by winds and currents eastward through the lake. Eighty percent of Lake Erie’s total inflow of water comes through the Detroit River. Eleven percent is from precipitation (rain and snow). The remaining nine percent comes from the other tributaries

THE GREAT LARGEST 10 LIBRARIES IN THE WORLD ACCORDING TO THE COLLECTION OF ITEMS

Library is a building or room containing collections of books, periodicals, and sometimes films and recorded music for use or borrowing by the public or the members of an institution.

The Polish-language books from the library (numbering some 55,000 titles) were returned to Poland by the Russian SFSR in 1921. For five years after its foundation, the library was run by Comte Marie-Gabriel-Florent-Auguste de Choiseul-Gouffier.

The Royal Library in Copenhagen is the national library of Denmark. Collection of books are more than 35.1 million in this Library and it is largest in the Nordic countries. In 2017 it merged with the State and University Library in Aarhus to form a combined national library. The combined library organisation is known as the Royal Danish Library. The “Black Diamond” is a characteristic new library building at the waterfront of Copenhagen. The building from 1999 is designed by the Danish architects Schmidt, Hammer and Lassen. The Library building is shiny, black facets mirror the sea and the sky at the harbour front. It is an extension to the Royal Library. It is founded in 1648. It houses many ancient manuscripts, notably The Gutenberg Bible and the manuscripts and letters of Hans Christian Andersen. The name refers to the prismatic sharp edges and the black marble plates and glass of the exterior, that reflects the water of the harbour. Also from the wave-like balconies of central foyer, that cuts into the building as an 24 meter high atrium, there is a panoramic view over the harbour.
The variety of cultural activities of the new building has turned The Royal Library into a central cultural centre of Copenhagen as part of the harbour promenade. The ceiling of the bridge between the old and the new is decorated by the Danish artist Per Kirkeby. In the old building of The Royal Library a Jewish museum has been designed by Daniel Libeskind in 2004 with sloping floors and light wooden interior.

The glass facade is held by iron girders weighing approximately one metric tonne per metre.

  1. The National Library of China

The National Library of China in Beijing has many rare Chinese items such as ancient books, oracle bones and tortoise shells from the Shang dynasty, and Buddhist manuscripts from the sixth century. Collection of items are more than 35.1 million in this Library. In 1916, the library received depository library status. In July 1928, its name was changed to National Peiping Library and was later changed to the National Library. The design of KSP Jurgen Engel for the new National Library of China in Beijing was the winning entry in an international competition. It is founded in 1909. The tripartite design of the library, symbolizing the past, present and future, consists of a solid base, a glazed center section enclosing structural cores and a steel-clad volume at the top. The stone-clad plinth houses the books and documents, representing China‘s rich cultural tradition. The steel box at the top houses the digital library. Weighing 10,388 tons, the 120 × 105 m earthquake-proof steel of the roof structure is designed as a steel lattice framework. Six reinforced cores transfer this load to the base, thus enabling the column-free floating ceiling over the grand reading room.
The glazed center section accommodates the public information area, access to reading rooms, foyer and cafeteria – all activities anchored to the present. The NLC faces the challenges of readership in the technological age. The creation of the National Digital Library is part of a strategy to combat this trend and to provide integrated services that include the availability of 10,000 e-books, mobile phone enabled library services and the use of RFID technology for the ease of locating items. Web pages, e-journals, blogs and so on – that appear only electronically.” With only 20 % of the National Library’s holdings available to the public in digital form in 2008, the Digital Library will greatly increase the reach of the National Library.
