Situated in a National Park Nelson lakes(New Zealand), Blue lake, known as Rotomahana – holds the title of the cleanest lakes in the world. Scientific tests carried out in 2011 the new Zealand National Institute of water and atmospheric research (NIWA) showed that Rotomahana – pristine freshwater lake known to man.
According to research it was noted that visibility through the water is 80 meters.Blue lake is characterized by purple-blue shades which may be seen in clear water like this:
Blue lake fed by another, nearby, lake Constance:
The lake is situated at an altitude of over kilometers above sea level, to be precise – 1200 meters. The water temperature is always within 5-8 degrees Celsius. Pure Blue lakes are sacred to local Maori tribes, and to enter into the lake is strictly prohibited. Even to make underwater photos, the authorities had negotiated with Maori representatives dive into the water.

The lake — it is a closed recess sushi filled with water and which has no direct connection with the ocean. Unlike rivers, lakes — the reservoirs slow water exchange. The total area of the lakes of the Earth about 2.7 million km2, or about 1.8% of the land surface. Lakes are everywhere, but unevenly. On the geographical distribution of lakes is greatly influenced by the climate, causing them to diet and evaporation, as well as the factors contributing to the formation of the lake basin. In areas with a humid climate, many lakes, they are flowing, fresh and mostly running. In areas with a dry climate, ceteris paribus smaller lakes, often dry, often closed, and that is often salty. Thus, the distribution of lakes and their hydrochemical characteristics due to the geographical zoning .
The largest lake — Caspian (area 368 km2). The largest are lake superior. Huron and Michigan (Sat. America), Victoria (Africa ), The Aral Sea (Eurasia ). The most profound — Baikal (Eurasia) — 1620 m and Tanganyika (Africa) — 1470 m.
Lakes are often classified by four characteristics:
the origin of lake basins;
the origin of the water mass ;
the water regime;
the salinity (amount of dissolved substances).
Origin of lake basins of the lake are divided into five groups.
1. Tectonic lake basins are formed as a result of the formation Continue reading
Lake Baikal – the oldest and deepest lake in the world, one of the greatest freshwater reservoirs in the world. It possesses unusual magnetic properties. It is celebrated by all the tourists who at least once in life visited the planet’s most unique lake, located in Russia. Primarily on the Baikal go for a healing holiday, getting natural and cleaning. Travel thousands of miles by plane, train, car to see its wonderful spaces.
Lake Baikal is located in the South of Eastern Siberia, between Irkutsk oblast and Republic of Buryatia. Baikal is known worldwide. In 1996 the lake was included in the UNESCO world natural heritage site by UNESCO. It flows about 350 lakes and rivers, constantly filling his water. Interestingly, it derives from only one river – the Angara. And the amount of water exceeds the volume of all the combined five Great American lakes. Lake Baikal is sometimes called the sea.
The extraordinary purity and transparency of the lake makes it beyond comparison with other reservoirs of the planet. It absorbs 20% of global and 90% of Russian reserves of fresh water corresponding to all the parameters of the best quality drinking water. From lake Baikal to drink Continue reading
