List of Top 9 Deadliest Lakes  in the World

26th February, 2024


In 1986, this crater lake silently released a massive cloud of carbon dioxide. The gas suffocated over 1,700 people and thousands of animals in nearby villages. Degassing efforts are ongoing to prevent another disaster.

Lake Nyos (Cameroon)

Lake Kivu (Congo)

This lake holds massive amounts of carbon dioxide and methane trapped beneath its depths. A volcanic eruption or earthquake could cause a "limnic eruption," releasing deadly gases. Scientists monitor the lake closely, hoping to minimize risks to millions living nearby.

Lake Monoun (Cameroon)

Another Cameroonian crater lake, Monoun, suffered a limnic eruption in 1984, killing 37 people. The exact cause remains debated, but volcanic activity is a prime suspect.

Boiling Lake (Dominica)

True to its name, this lake's water temperature can reach 197°F (92°C) near the edges. Steam and volcanic gases make getting close incredibly dangerous.

Lake Natron (Tanzania)

This lake's extreme alkalinity (pH as high as 10.5) is deadly to most wildlife. Calcification turns unfortunate animals into eerie, statue-like figures.

Lake Karachay (Russia)

Decades of use as a nuclear waste dumping ground turned this lake highly radioactive. It was partially filled in, but radiation levels remain hazardous.

Carbon dioxide seeping from volcanic fissures has killed trees surrounding this lake. ●  The gas continues to pose a hazard for hikers venturing too near.

Horseshoe Lake (California, USA)

It is a popular diving spot, but its hydrogen sulfide-rich water is toxic. Several divers have tragically perished in the lake.

Blue Hole (New Mexico, USA)

● One of the Great Lakes looks inviting, but dangerous rip currents and unpredictable weather are deadly. ●  Drownings occur with tragic frequency, mainly when swimmers are unaware of the hazards.

Lake Michigan (USA)

This is not an exhaustive list. Nature is always unpredictable; even seemingly safe lakes can carry hidden dangers. Always exercise caution around any body of water!
