Not all lakes are suitable for swimming. In some of them it is more than dangerous.
Monster in the lake: Brosno (Russia)
Locals often see an ancient pangolin in this lake. Scientists have tried to help them find this terrifying "dragon Brosno", but to no avail. What is really going on here? The decomposition process that occurs at the bottom leads to the appearance of bubbles on the surface. These bubbles are so powerful they can flip a boat, so it's no surprise that they cause fear among the locals.
Lake Hillier (Australia)
Can't believe your eyes? Rose water, eucalyptus forests and no monsters? You can die from one of its kind. But seriously, scientists attribute the unusual pink color of the water to a variety of microorganisms that live in the lake.

Acid Lake Ijen (Indonesia)
Meet the most acidic lake on the planet. The water is a delicate turquoise color, 200 degrees Celsius at the bottom, deadly methane that glows a strange blue at night. However, regardless of this, the inhabitants of the surrounding area manage to collect sulfur from the shores of this lake, without even wearing protective masks.
Unexpected Lake: Gafsa (Tunisia)
The strangest thing about this lake is that it appears right in the middle of the desert. According to scientists, this lake appeared as a result of seismic activity, but it is still not clear how this could happen so quickly. However, it is not recommended to swim in it, as it contains potentially poisonous algae, and its waters can also be radioactive due to nearby phosphate mines.
Boiling Lake (Dominica)
This lake is literally boiling. The water temperature here is 92 degrees Celsius. You cannot swim in this lake if you are not eager to boil alive. From the point of view of science, this is very easy to explain: it is located in the crater of a volcano, so the water in it is constantly heated from below.
Killer Lake Nyos (Cameroon)
This lake killed 1,746 people. On August 21, 1985, a cloud of deadly gas appeared in the vicinity of Nyos, killing all life. As the scientists explained, this was due to a volcano located at the bottom of the lake. Carbon dioxide from the volcano entered the water, rose to the surface and spread everywhere in the form of a cloud. Before you go swimming, check what is on the bottom.
Surprise from the bottom: Lake Michigan (United States of America)
At first glance, this lake looks great. Delicate color of water, absolutely no monsters and other horrors. However, the trap is at depth. There are very strong spontaneous currents that carry people away from the coast. And in the autumn season, waves appear on the surface of the lake, which are in no way inferior to oceanic ones.
Roopkund, or Skeleton Lake (Himalayas)
The remains of more than two hundred people who died a mysterious death remained at the bottom of this lake for eleven centuries, until the British army discovered them in 1942. What happened to 200 people at the same time? The answer was simple: a deadly hail the size of cricket balls (7 centimeters in diameter). It is now forbidden to swim in this lake, since no one knows what other deadly surprises may await here.
Explosive Lake: Kivu (between Democratic Republic of Congo and Rwanda)
This is one of the most dangerous reservoirs on Earth. If volcanic activity or even the weakest earthquake occurs here, it will instantly explode, killing two million people living nearby. The reason is thick layers of carbon dioxide and large amounts of methane in the water.
Lake Natron (Tanzania) turns all life into stone
This lake has a very unusual way of dealing with creatures that die in its waters. It turns them into statues and then throws them ashore. Hydrogen and alkali create salt and limestone that preserve organisms and prevent them from decomposing.
Bonus: Jacuzzi of Despair - Toxic Salt Lake (Gulf of Mexico)
This lake has earned its nickname "the whirlpool of despair" for its relatively pleasant temperature (19 degrees Celsius) and bubbles. But at the same time, it contains a large amount of methane and sulfides, therefore it is very toxic.
