The most beautiful and clean lakes. The cleanest and most transparent lake in the world

lakes- natural reservoirs of water not connected to the oceans. Since ancient times, people settled on their banks and used these reservoirs for household and drinking needs. However, the impact of human activities on lakes is much higher than on rivers.

The water in such reservoirs changes much more slowly, so many lakes, including those related to natural attractions, are heavily polluted. For this reason, the most clear lakes in the world are located in remote areas far from human settlements.

Which lake is the cleanest and most transparent in the world?

Several reservoirs located in different parts of the world are fighting for the title of "the cleanest lake".

Blue - there is no equal in purity

Until recently, Baikal was considered the cleanest lake on Earth. However, recently he was pushed off this unofficial pedestal Blue Lake V .

Its Maori name is Rotomairevenua, meaning "lake of the peaceful land".

In 2011, studies conducted by scientists showed that it was Blue Lake that deserved to bear the title of the cleanest lake. In terms of its transparency, the waters in the Blue Lake are comparable to distilled water, and the visibility of the water column is approximately 80 meters.

The blue lake is fed by the waters of the neighboring lake Constance, in which they undergo a kind of filtering. The water in Blue Lake changes completely within 24 hours. Due to the landslide rocks that make up the bottom of the reservoir, the water in it has different shades:

• Blue;
• Emerald;
• The rarest violet the color that distinguishes the most pure reservoirs.

The lake is located on the largest island of New Zealand - south island. Swimming and diving in the Blue Lake is strictly prohibited not only because of the unique cleanliness, but also because of its sacred status among the local Aborigines - the Maori.

Bowman - crystal clear

The most transparent Bowman Lake, Montana, is considered the lake of peace. A small body of water with an area of ​​less than 10 km² is located in the reserve glacier.

The water in this lake is so clear that you can see every pebble at the bottom. The high transparency of Bowman Lake is preserved, among other things, because it is practically there are no tourists, although visiting the lake is not prohibited.

A dirt road leads to the lake, and on its coast there is a campsite where anyone can order a boat ride on the water surface or fishing.

In addition to its extraordinary appearance, the Lake of the Five Flowers carries a few more mysteries. For example, water level it never changes, although the neighboring lakes dry up in the summer. In addition, in winter the reservoir never freezes. All these factors influenced the fact that the lake acquired a sacred status among the locals.

Peyto

Peyto Lake is located in Canadian rocky mountains, in the province of Alberta, . Alpine lake, located at an altitude of almost 2 km above sea level, is the most popular and famous among the lakes located entirely on Canadian territory.

Peyto gained its enormous popularity for the unusual color of the water in the spring.

When the mountain glaciers that feed the lake begin to melt, the glacial flour gives water pale turquoise color, which is found only in tropical seaside resorts.

Transparent turquoise water against the backdrop of harsh mountains covered with coniferous forests creates several surreal painting. Also unusual is the shape of the lake, resembling a wolf's head.

largest lake system

Great Lakes, located on the border of the USA and Canada, this is the largest lake system in the world, which only Baikal can compete with in terms of water reserves. The lakes are of glacial origin and formed about 10 thousand years ago. The Great Lakes include:

1. Lake Upper(the largest lake in the system);
2. Huron;
3. Michigan;
4. Erie;
5. Ontario.

Also, the Great Lakes system includes a small lake compared to the rest. St. Clair, however, it does not apply directly to the Great Lakes. Lake Superior is the largest freshwater lake in the world, second only to the salty Caspian Sea.

Hundreds of rivers and streams flow into the Great Lakes system, so the water in them has a normal color. A large number of people living on the shores of the lakes, rapid economic and economic activity led to the fact that by the middle of the 20th century the waters of the lakes were strongly got dirty.

Measures taken by the authorities of the United States and Canada have led to the fact that over the past decades the water has been significantly purified.

Now, environmental problems are largely left behind, and many species of fish are found in the lakes, including trout, which can only live in the purest water.

Last look at the interesting video about the cleanest lake in the world:

September 18 is World Water Quality Monitoring Day. This day is intended to remind society of the problems of water pollution around the world. Everyone is invited to conduct a series of simple tests to determine the quality of water in local reservoirs, and publish the results on the World Water Quality Monitoring Day website.

In this post, we recall the 3 cleanest reservoirs in the world.

1. Baikal (Russia)

And we will start with such a native Russian heart of the lake as Baikal. This miracle of Russia is located in the southern part of Eastern Siberia. Baikal can be undoubtedly attributed to the deepest and cleanest lakes in the world! The area is 31,722 km², and the average depth is 744 m. The water here is very clear - in some seasons, the transparency reaches 40 meters. ( photo: open sources)

2. Lake of Five Flowers (China)

Locals say about this lake, located in Sichuan province, like this: "Nothing on earth can compare with Jiuzhaigou." The water in the lake is so clear that you can see the trunks of fallen trees at the bottom. A specific color that changes depending on the season, the water acquires due to mineral salts and aquatic plants. ( photo: open sources)

3. Lake Königssee (Germany)

This lake, 7.7 km long and 5.22 km² in area, is located in the southeast of Bavaria and belongs to the Berchtesgaden National Park. Formed as a result of melting glaciers. Königssee is one of the three deepest lakes in Germany (average depth is 98 meters). The places themselves real paradise for the photographer! The surrounding mountains create stunning landscapes. ( photo: open sources)

With the approach of summer, we increasingly dream of plunging into cool and clean water. True, not always accessible beaches delight with impeccable cleanliness. There are, however, places on Earth where the water is really transparent and practically untouched by civilization.

In today's top ten, we have collected cleanest waters in the world. Yes, not all of them are suitable for swimming, but enjoying the contemplation of the bottom through the 40-meter water column is a special pleasure.

10. Crater Lake (Oregon, USA)

This crater lake is famous for its clear water and deep blue color. The lake was formed over 7,700 years ago. One of the attractions of Crater is a huge log that has been floating vertically over the entire surface for more than a hundred years.

9. Buck Buck Beach (Borneo Island)

The water here is so clear that you can see every blade of algae that covers huge boulders. This beach is not popular among tourists because entry into the water is very inconvenient. It was this circumstance that made it possible to keep the water crystal clear.

8. Lake Mashu (Japan)

The body of water in the Akan National Park is considered one of the cleanest in the world. The lake is located at the foot of the mountain of the same name. The transparency of the water here is amazing - it reaches more than meters. In order for tourists to appreciate the local beauty, several viewing platforms are equipped for them above the water.

7Flooded Red Stone Cave (Australia)

Tourists love to visit this place, looking at the smallest pebbles at the bottom of a rather deep lake for hours. The transparency of the water is somewhat reduced by slight ripples due to a nearby waterfall.

6 Peyto Lake (Canada)

The cleanest lake, located in Banff National Park, was formed as a result of the melting of a glacier at an altitude of 1860 meters. One of the "highlights" of the lake is the tropical turquoise color of the water.

5. Lake Baikal (Russia)

boasts unusually clear water. In some places you can see the bottom, located at a depth of more than meters. Special purity of Baikal water is reached in spring.

4. Lake of Five Flowers (China)

An unusual lake is located in Sichuan province. The bottom of the lake is covered with trunks of fallen trees, which can be seen in every detail, thanks to the crystal clear water. The lake is fed by underground springs, the warmth of which does not allow it to freeze even in harsh winters.

3. Jenny Lake (Wyoming, USA)

The reservoir was formed about a thousand years ago in the process of melting glaciers. By the way, the lake got its name from an Indian girl who married the British pioneer Richard Lee.

2. Rio Sucuri (Brazil)

This river is so clean and transparent that it creates the illusion that fish floating in the water are fluttering in the air. Together with the banks covered with lush greenery, the Sukuri River creates a very picturesque landscape that attracts tourists. One of the most popular activities on Sukuri is snorkelling.

1. Lake Königssee (Germany)

This one of the world's cleanest reservoirs formed as a result of melting glaciers. Only boats with electric motors, rowing boats and pedal catamarans are allowed to move around the lake. In the very middle of the lake you can hear an unusually clear and clear echo, which is facilitated by the surrounding mountains.

The first thought that arises when looking at this stunning body of water is to jump into its crystal clear water and splash around until exhausted.

The cleanest and concurrently the most beautiful lake on our planet is called Blue Lake and is located on the South Island of New Zealand. The first thought that arises when looking at this stunning reservoir is to jump into its crystal clear water and splash in it until exhaustion. But, unfortunately, this is strictly prohibited!

Incredible landscape. The South Island in New Zealand is the last unspoiled corner of nature.

Relic forests, sheer cliffs and waterfalls - a stunning landscape.

There, deep in the mountains, is the purest lake on Earth fed by the purest water source.

Blue Lake (or in the Maori language - the indigenous people of New Zealand - Rotomairewhenua) is located in the Nelson Lakes National Park on the South Island.

The water in it is so clear that when diving you can see far ahead of you.

Laboratory tests have shown that the visibility range is from seventy meters.

For comparison: in distilled water, this figure is about eighty meters.

This photo shows: the water in the lake is so transparent that it cannot be distinguished from the air.

Swimming is prohibited in the lake due to nature conservation.

Only scientists can obtain special permission to dive into the lake in order to take photographs such as these.

Water of a bewitching azure color, with a visibility of several tens of meters - some of the planet's reservoirs are still distinguished by incredible environmental performance. They miraculously managed to avoid the harmful influence of civilization, for thousands and millions of years the water in them remains crystal clear. Some of the cleanest lakes and rivers on the planet are located in incredibly hard-to-reach places; tourists need to overcome a difficult path to see them. Others, on the contrary, have long been centers of tourist life, which does not prevent them from maintaining their unique environmental performance. All the cleanest reservoirs of the planet are incredibly beautiful and, of course, deserve the attention of the most sophisticated travelers.

Crater Lake, USA

In the United States, in the state of Origon, there is an incredibly beautiful lake Cryter, it was formed in the crater of an extinct volcano. This lake has become famous all over the world for its unique deep blue water, which is considered one of the cleanest in the world. According to scientists, this lake was formed more than 7.5 thousand years ago, its average depth is about 350 meters. The size of the lake is also very impressive, its length is about 9.6 km, and its width is about 8 km.

This lake is one of the deepest not only in the United States, but also in North America. A few years ago around a unique lake was formed national park, on the territory of which today they conduct interesting excursions. The main event for travelers is the ascent to the crater of an extinct volcano, this is the only way to see the beautiful lake with your own eyes. In recent years, about 400,000 tourists from all over the world annually visit this amazing nature reserve.

The crystal clear lake attracts not only inquisitive travelers, but also ecologists and researchers. Several years ago, a group of scientists conducted an interesting experiment here. The fact is that initially no species of fish were found in Lake Kreiter, ecologists decided to add some species of trout and salmon here. Their experiment was a complete success, today the lake is inhabited by fish. Tourists are even allowed to fish here, subject to the only condition - they must use artificial bait.

Lake Zyuratkul, Russia

In Russia, among Ural mountains located amazing lake Zyuratkul, it is located at an altitude of 724 meters above sea level and is the highest mountain lake in the Urals. The maximum depth of this lake is relatively small and is about 12 meters, and the area of ​​\u200b\u200bthe reservoir is 13.5 square meters. km. Today, the amazing lake is considered one of the cleanest in the world, despite the fact that the water in it is by no means transparent. It has a cloudy tea shade, due to the fact that many streams flowing into the lake originate in swamps.

The area near the lake is famous not only for its natural beauty, but also for its historical sites. During the study, scientists discovered several important archaeological sites, here they raised the tools of labor of primitive people and found a giant geoglyph. For local residents, Lake Zyuratkul has been a sacred landmark for hundreds of years; many interesting legends and beliefs are associated with it.

In the forests located along the shores of the lake, the Old Believers performed their rituals hundreds of years ago, while walking through them, even today you can see unusual monuments carved from wood. In the territory national park Zyuratkul created excellent conditions for recreation. There are several equipped camping areas here, so in the warm season, travelers can stay in these picturesque places for several days. Hundreds of different excursions are held here, during which you can see the most significant natural attractions, as well as unique historical areas.

Piccaninny Ponds, Australia

In Australia, on the territory of the Piccaninny Reserve, there is a system of ponds of the same name, which have recently been considered a favorite vacation spot for divers. In total, there are three ponds in the system, all of them are characterized by crystal clear water. However, each of these ponds has its own unique features. The "First Pond" is the smallest, its depth is only 10 meters. Much deeper is the "Abyss" pond, its maximum depth is 100 meters. The water in this pond is crystal clear, visibility in it can reach 40 meters.

The most unusual and interesting of the three ponds is the "Cathedral", its depth is 35 meters. This pond was formed in a grotto of a limestone formation and is most popular with divers. The system of ponds is located in a special swampy zone, which is notable not only for its reservoirs, but also for its unique vegetation and fauna. This swampy area is home to several rare species of birds, the observation of which attracts not only ornithologists, but also tourists.

On the territory of Piccaninni Park, there are many hiking trails for tourists, as well as several excellent viewing platforms from which you can admire the beautiful ponds and the surrounding landscapes. The Piccaninny National Park was established in 1969 and covers an area of ​​about 8.6 sq. km. km. Since a few years ago the ponds were open for snorkeling and diving enthusiasts, today ecologists control their cleanliness with particular care. Those who want to swim in these pristine ponds will need to comply with some formalities.

Lake Masyuko, Japan

In Japan, on the territory of the island of Hokkaido, there is another crystal clear lake - Masyuko. It is located in the Akan Nature Reserve, on all sides the lake is surrounded by incredibly beautiful mountain ranges covered with dense vegetation. This crystal-clear lake was formed in the caldera of an active volcano, the water in it has a deep blue color due to its special mineral composition. Hundreds of tourists visit this beautiful lake every day as part of organized excursions around the national reserve.

While walking through the mountainous regions, they will have the opportunity to see many rare plants, animals and birds. It is most interesting to walk through these colorful places in the summer. However, visiting the reserve also has its charms in winter. On the territory of the national park there is another crater lake - Kussiaro, it also has its own unique features. The thing is that several hot springs flow into it, which do not allow some areas of the lake to freeze even in winter. This feature attracts many heat-loving birds to the reservoir; whooper swans always winter here.

The main feature of Lake Masyuko is that not a single stream flows into it, nor does it flow out either. Researchers believe that it is this feature of the lake that allows it to maintain its crystal clearness for hundreds of years. It is also worth noting that there are several interesting miniature villages on the territory of the reserve, where you can get acquainted with the life of local residents and buy interesting souvenirs.

Lake Bowman, USA

In the United States, there is the amazing Lake Bowman, which is also known for its purest water. It is located in the state of Montana, in the territory national reserve Glacier. Despite the fact that the reserve is rich in a variety of natural attractions, it is still visited by a very small number of tourists. This largely contributes to the preservation of the unique ecosystem here. Lake Bowman is impressive in scale, its length is about 11 km, and its width is about 1.5 km.

This fabulously beautiful lake is considered one of the most transparent in the world, today tourists are provided with all the conditions for organizing interesting holiday. They can not only walk around the reserve, but also spend several days in a tent camp.

Toilets and even showers are equipped on its territory, and every effort is being made to preserve the ecology of these places. Today, the main guests of this "resort" are local residents, although in recent years Bowman Lake has attracted a sufficient number of foreign travelers. It is not difficult to get to this wonderful lake; a motor road runs along the part of the reserve.

Lake Sheosar, Pakistan


In the northern part of Pakistan, on the territory of the Deosai National Park, there is a fabulously beautiful Lake Sheosar. It gained popularity among tourists precisely because of its crystal clear water. For hundreds of years, this lake has remained one of the cleanest reservoirs on the planet. The maximum depth of this lake is 40 meters, its length reaches 2.3 km, and its width is 1.8 km. This lake is located in a very inaccessible mountainous area, at an altitude of 4,142 meters above sea level.

For travelers, both car and walking tours of the nature reserve are organized. It takes just a few hours to get to the hard-to-reach mountainous area by jeep, while the walk usually takes at least two days. It is best for nature lovers to walk around the reserve on foot. There are several specially designated areas on its territory where you can set up a tent camp.

best time the period from the beginning of June to the end of September is considered to visit the beautiful lake and walks around the reserve, at which time the plateaus surrounding the lake are covered with carpets of bright colors. Butterflies are one of the main inhabitants of these picturesque places; there are several dozen species of them here. Already in November, a beautiful valley and a lake hides snow under its thickness, it completely disappears only by May. During the cold season, excursions around the reserve are not carried out.

Peyto Lake, Canada

In Canada, one of the cleanest lakes is worth looking for on the territory of Banff National Park, where the world-famous Peyto Lake is located. This lake is located in an incredibly beautiful foothill area, its area is about 5.3 square meters. km. The length of the lake stretches for 2.8 km, and its average width is only 800 meters. The first to discover this amazing lake was the traveler Bill Peyto, in honor of his discoverer, the lake got its name.

One of the main features of the lake is its unusual shape, if you look at it from a bird's eye view, it resembles a huge wolf's head. The water in the lake has a rich turquoise hue, which also attracts attention. Every year the lake is replenished with water from nearby glaciers. Mountain streams bring with them the smallest particles of minerals into the lake, which make the color of the water so unusual. Now, several comfortable recreation centers are equipped for tourists on the shore of the lake. Here you can have a great rest for several days and enjoy the natural splendor.

Fishing enthusiasts are especially attracted to these places; rainbow trout, salmon, pike and other species of noble fish are found in the lake.

Lake Baikal, Russia

In the south of Eastern Siberia there is a world-famous attraction - Lake Baikal. It is the world's largest reservoir of fresh water and the most deep lake on the planet, its maximum depth is 1,642 meters. The area of ​​the lake is 31.7 sq. km. The lake is interesting not only in itself, it is surrounded by unique natural landscapes. Many unique endemic animals live here, and you can also see a lot of rare plants.

Lake Baikal has a tectonic origin, the water in it is considered one of the cleanest in the world and is home to valuable fish species. One of the main features of water is the high oxygen content, while the amount of minerals is very small. Lake Baikal is also one of the coldest in the world, the water temperature in it, even in the summer months, does not rise above +8 degrees Celsius.

One of the main unresolved issues related to the lake remains the theory of its origin. According to scientists, its formation was provoked by tectonic activity, the age of the lake is at least 25 million years. The inhabitants of the lake are of great interest to researchers; there are more than 2,600 species of them here. More than half of the aquatic inhabitants are endemic, they cannot be found in any other body of water in the world. One of the most important ecological problems of Lake Baikal is sewage. Many rivers flow into the lake, the water in some of them is polluted by industrial waste.

Moraine Lake, Canada

In Canada, there is the famous glacial lake Moraine, it is located on the territory of Banff National Park. This lake is very small, its area is only 500 square meters. meters, and the maximum depth reaches 14 meters. However, the beauty of this lake is difficult to find equal. The discoverer of this unique natural landmark was explorer Walter Wilcox. When he discovered this lake, then inseparably admire it for half an hour. Later, in his manuscripts, the scientist noted that these were the happiest half an hour in his life.

This lake is located in a very inaccessible mountainous area, so for a long time no one knew about its existence. The water in the lake, which fills it from year to year during the melting of glaciers, has a rich sapphire hue. Against the backdrop of the surrounding mountain ranges, the lake looks fantastic. The best time to visit the lake is June, when the peak of the melting of glaciers falls, the lake reaches its maximum size.

Travelers can visit Moraine Lake only from May to September, the rest of the year the mountain road is closed for safety reasons. You can easily get to the lake by car; the nearest large settlement to it is the city of Calgary. In recent years, organized excursions have been conducted to the lake, according to tourist route bus runs. Half an hour from the lake there is a small mountain village, which will also be very interesting to visit as part of the tour.

Jenny Lake, USA

Jenny Lake is located in northwestern Wyoming, today it is part of the Grand Triton National Park. This lake also has a glacial origin, it is located at an altitude of more than 2,000 meters above sea level. According to researchers, the lake was formed about 12,000 years ago, its maximum depth reaches 129 meters, and the area is about 482 square meters. km. Despite the fact that this lake is one of the cleanest in the world, motor boats are allowed on it, which is actively used not only by researchers, but also by tourists.

The main route, formed along the shores of the lake, is called the Jenny Lake Trail. Excursions are carried out here not only during the day, but also at night. Nearby is the beautiful Cascade Canyon, which is also an important attraction of these places. The name of the lake has a very interesting story. In 1872, one of the first large expeditionary groups worked on the lake, led by the Englishman Richard Lee. This beautiful lake was later named after his wife Jenny.

Another attractive feature of the reservoir is the diversity of fish species. Fishing was allowed here several years ago. The most treasured prey of fishermen is trout, to go fishing here, you need to get a special license. Tourists are allowed to travel to these places only accompanied by guides, among the inhabitants of the nearby forests there are many predatory animals, bears are also found here. Like many years ago, today the national park attracts hunters, and climbers like to relax here.

Lake Pukaki, New Zealand

There are also many wonderful lakes in New Zealand, noteworthy tourists. One of them is worth looking for on the South Island, where the beautiful Pukaki Lake is located. This lake of glacial origin has become known throughout the world due to the rich blue color of the water, which, among other things, is also incredibly clean. The area of ​​the lake is 178.7 sq. km, it is located at an altitude of more than 500 meters above sea level. This fabulously beautiful reservoir stretches for 15 km in length, and its width is about 8 km.

A few years ago, Lake Pukaki became part of a large hydropower system, experts made sure that such use of the reservoir would in no way affect its environmental performance. For local residents, the appearance of a hydrotechnical hub was a real breakthrough, it was thanks to the lake that they finally received stable electricity.

Not everyone knows that the original glacial lake was very small, its maximum depth was no more than 25 meters. When in the 40s of the last century they began to build a hydrotechnical station, the volume of the lake was significantly increased. Initially, in the center of the lake there was a small island, which, as a result of the expansion of the reservoir, was flooded. The water in the glacial lake is always very cold, so not everyone dares to swim in its crystal clear azure water. Even at the height of summer, its temperature is no more than + 7 degrees Celsius. Local residents have many beautiful legends connected with the lake. It got its name in honor of one of the mythical warriors.

Lake Tahoe, USA

In California, there is an amazing freshwater Lake Tahoe, it is located in the picturesque foothills of the Sierra Nevada. This lake is well known to tourists, in the immediate vicinity there are several popular ski resorts. Lake Tahoe is the second deepest lake in the United States, with an average depth of 305 meters and an area of ​​about 495 square kilometers. km. Of the most beautiful lakes in the world, Tahoe is considered one of the most easily accessible; major highways run along the entire perimeter of the reservoir.

The lake was formed at the site of a geological fault in the earth's crust about 3 million years ago. Today, not only the lake itself with fantastic sky-colored water is of great interest, but also the coniferous forests surrounding it. Here you can see many rare species of pines and fir, as well as rare species of shrubs and herbs. The lake was discovered relatively recently, in 1844, its discoverer is Lieutenant John Fremont.

He explored these mountainous regions in search of a river, and discovered an incredibly beautiful lake, which, after a few years, was explored by scientists from all over the world. Most tourists began to visit these places after 1960, when the Winter Olympic Games were held at one of the local resorts. Since those times, an excellent tourist infrastructure has remained here, today comfortable hotels are located near the lake, and there are also many ski slopes of various difficulty levels. Hikers will also find it interesting to relax here. Exciting excursions are held near the lake at any time of the year.

Blue Lake, New Zealand

One of the cleanest and most unusual lakes on the planet with the complex name Rotomairewhenua is located in New Zealand, translated from the Maori language, its name means "Blue Lake". This miniature freshwater lake is located within the Nelson National Wildlife Refuge and is part of a complex system of lakes. Ecologists began to study the reservoir in detail only in 2011, they accidentally discovered that the water in the lake is extremely clean.

Visibility in it can reach 80 meters. From year to year, the lake is fed by water from nearby glaciers. Flowing from the mountain peaks, it passes through many natural rocks that act as a natural filter. Largely due to its purity, the water in the lake has an amazing shade that varies from deep blue to light purple during the day.

One of the first specialists to show interest in the lake was hydrologist Rob Mirriles. After admiring the crystal clear water, travelers should definitely take a walk through the forests surrounding the reservoir and mountain ranges. There are no tourist bases near the lake; it is extremely rare to meet travelers here. The main visitors to these picturesque places are researchers and ecologists, not so long ago, as a result of a major study, the water in the Blue Lake was equated in properties and quality with distilled water.

Petermann River, Greenland

Some rivers also amaze with amazing purity of water. An excellent example is the Petermann River, located in Greenland, known to a wide range of travelers under the unofficial name of the Blue River. The location of the river is the glacier of the same name, which melts in the summer and forms many small streams. All of them converge into a single river, the water in which has a rich blue hue.

The incredibly beautiful and clean river poses a huge threat to the world ecology. In recent years, the Petermann Glacier has begun to melt four times faster, which contributes to a significant increase in the level of the world's oceans. According to researchers, in the coming years, the glacier will melt even more intensively, which can lead to serious environmental disasters. In the meantime, the crystal clear river is of great interest to scientists. They can assess the composition of glacial waters that have been frozen for millions of years.

It is very difficult for ordinary travelers to get to this remote corner of the world with an incredibly harsh climate; this can only be done together with organized expedition groups. Now ecologists are trying to take all possible measures to minimize the influx of glacier meltwater into the world ocean. In the coming years, he may lose up to 100 square meters. kilometers of ice, this amount of melt water would be enough to provide a large metropolis for 10 years.

Weddell Sea, Antarctica

Off the coast of West Antarctica lies the beautiful Weddell Lake, which is also one of the cleanest bodies of water on the planet. It bears its name in honor of the discoverer J. Weddell, who made an expedition to these places in 1832. The area of ​​the sea is 2,900,000 sq. km, and its maximum depth reaches 6,800 meters. In addition to the incredibly beautiful sky-colored water, the sea is distinguished by a huge number of ice floes that float in it all year round.

This beautiful clear sea has become home to thousands of aquatic inhabitants, huge populations of whales, seals and fish live here, and penguins are also typical inhabitants of these places. Today, the Weddell Sea is considered the cleanest in the world. The last major survey of its water was in 1986, with an average visibility of 79 meters, which is in line with distilled water.

Far from all research groups decide to swim in this sea, not to mention ordinary tourists, drifting ice poses a huge threat to ships. Many natural and physical phenomena are associated with the northern sea. The water in it never freezes, despite the fact that its temperature can reach -25 degrees Celsius. The Weddell Sea is the coldest and cleanest sea on the planet. To see it with their own eyes, travelers need to be part of one of the research expeditions, but they rarely go to this harsh sea.
