WHAT is the largest freshwater lake in the world
The largest reservoir of fresh water on planet Earth
Lake Baikal is not only the most voluminous lake. It is the deepest and one of the oldest. Baikal is the deepest cleft on the surface of the planet. This cleft is the most complex and least understood fault zone of the earth’s crust. The depth of the lake on average is 745 meters and the deepest point reaches 1637 meters. The lake stretches for 636 km, while its width is 80 km from the Surface of the lake is 31 000 km2.
This ancient lake is formed 20-30 million years ago by tectonic shifts. Fresh and clean water in the lake is maintained by two factors. First, it is home to the endemic Baikal epishura – microscopic crustacean that filters a huge number of algae and bacteria. In addition, most of the watershed of lake Baikal supported by craggy rocks. Thus, the flow of water towards the lake is almost in contact with the sediment and minerals. This oligotrophic lake, and its water has an excellent drinking quality.
Flows into the lake, 365 rivers, including the Yenisei – the largest river of Siberia. The lake contains 20% of fresh water on the Earth’s surface. The volume of fresh water in the lake is 26 000 cubic kilometers. The ancient cistern is one of the cleanest in the world. Water extracted from the depths of the lake, you can drink without prior treatment. In winter the lake freezes and is covered by ice.
The most oligotrophic lake in the world
Lake superior relative to the system of freshwater lakes in North America, is the largest water surface area freshwater lake in the world. Its surface is 82 170 km2. It contains as much water as all the Great lakes combined: 11 600 cubic kilometers. Fresh water lake is 10% of total stock on the surface of planet Earth. The shore of lake superior is due rare natural phenomenon – snow lake effect, winter when cold air over a warm surface is saturated with water vapor, forms clouds, and then precipitation falls as snow.
The amount of water in the lake is enough to flood North and South America to a depth of 30 cm at its deepest mark in the lake is 400 m In lake superior receives more than 300 rivers and streams.
If you stretch the shoreline of the lake in a straight line, it would connect Bahamas and Duluth, a city in Minnesota, United States.
The average water clarity in the lake is 8 meters deep. This is the most clean and clear from the Great lakes and the most oligotrophic lake in the world. The length of the lake is 563 km long, 257 km and the width in the Summer sun on the Western shore of lake rolled on 35 minutes later than at its southeastern shore. The largest lake in the world Caspian sea. But it is not freshwater. The salinity of the water in it is approximately a third the salinity of the water in the seas of the planet.
Lake superior is one of the youngest lakes in the world. He is only 10 000 years.
