Boiling and radioactive: the most terrible lake of the planet

Toxic gases and radioactive radiation, human carelessness and mistakes of nature made these lakes the most dangerous on the planet.


The scenic lake Kivu, which is on the border between the Democratic Republic of the Congo and Rwanda, attracted the attention of scientists from all over the world, but the popularity of the reservoir is not linked to its beauty.

Under a layer of water of the lake keeps dangerous deposits of carbon dioxide and tens of billions of cubic meters of methane generated by bacteria in the pond. This deadly combination makes lake Kivu the real bomb. If in these parts there’s an earthquake, the deadly ingredients “mixed” and the lake will simply explode.

Scientists estimate that lake Kivu is a threat to at least two million people who live in a dangerous area. In the event of volcanic activity or earthquake they will be killed by the explosion of methane and of carbon dioxide poisoning.


Lake Karachay is located in the Urals, in the chemical plant “lighthouse”, and today is the most deadly lake in the world.

In 1951 the lake was used for storage of liquid radioactive waste, and over the past decade there has accumulated about 120 million curies of radioactive materials, mainly cesium-137 and strontium-90. The lake is so toxic that a five-minute visit to its shores is able to cause significant harm to human health, and a one-hour stay is guaranteed to end in death from exposure.

During a drought in 1961, the wind blew toxic dust, irradiating 500 thousand people, which is comparable with the effect of the atomic bomb dropped on Hiroshima. The last 20 years are working on filling the deadly lake.


The name of the lake speaks for itself. Located in Dominica, on the beautiful island in the Caribbean, this lake is the second largest natural hot spring on earth and is considered one of the natural wonders of the world.

The water temperature in the lake –80-92 °C, and in the center of the reservoir in some areas it reaches boiling point. The reason for this are faults on the bottom of the lake and volcanic activity-lava simply heats the water to such a record temperatures.


Despite the primitive name, horseshoe lake, located near the town of Mammoth lakes (Mammoth Lakes) in California, is considered a terrible silent killer.

The town of Mammoth lakes was built not in the best place – on top of an active volcano. For many years this lake has attracted people’s attention only because of its unusual curved shape resembling a horseshoe, but 20 years ago, residents noticed that the trees around the pond had become dry and die. After exclusion of all possible diseases, scientists have found that plants suffocate from excessive levels of carbon dioxide, which oozes through the ground from underground voids – magmatic chambers. People on this lake also acts detrimental: in 2006, three people took refuge in a cave near Horse horseshoe and died from carbon dioxide poisoning which has accumulated inside it.


Mono lake in California is very ancient. It is so salty (salt content more than twice exceeds indicators of the ocean) that it is no fish, but scientists try, its enterings in local water was not successful.

The pond was struck by its beauty of all who have ever visited its shores. But in 1941 it started to be too actively used to provide local residents with water. This went on for almost 50 years, the lake is strong words … When the water level dropped, exposing the hidden calc-tuff towers – one of the natural wonders of the lake.

The resource of this lake stopped in 1990, by which time Mono lost more than half its volume. Then a Committee was formed, which deals with matters of restoration of the unique waterfront.


Located in the crater lake Monoun at first glance looks like a normal pond. But actually it, as well as Kivu in the Congo is volatile.

During one eruption in 1984, Monoun killed 37 people, sending forth a cloud of carbon dioxide.


Only 62 km from Moon is another dangerous lake – Nous. In 1986, it exploded after ejection from the ground carbon dioxide, turned the water Nwas in carbonic acid. Was formed by a giant cloud of carbon dioxide, which has killed thousands of people and animals from the local towns and villages.

The lake today is a threat to the local population, because the slightest shifts of the earth’s crust and volcanic activity can cause a new explosion.


Lake Michigan, one of the five great lakes on the border of Canada and USA, also included in the list of deadly.

Warm water lake attracts hundreds of tourists and locals, who enjoy swimming here in the summer. But dangerous undercurrents, resulting from the unique shape of the lake, which annually claim the lives of people.

Michigan becomes especially dangerous in October and November, when sudden changes in air temperature and water can increase the speed and force of the currents.
