While specific data varies by region and timeframe, Lake Michigan consistently ranks as the deadliest in the U.S. due to its size, powerful currents, and steep drop-offs, leading to hundreds of drownings; globally, Lake Victoria sees extremely high fatalities, primarily among fishermen, and Lake Eildon in Australia leads its country for inland water deaths.
Lake Nyos. Considered the world's deadliest lake, Lake Nyos is a deep lake on the crater rim of an extinct volcano. Lake Nyos is a crater lake in the Northwest Region of Cameroon. It's a deep lake high on the crater rim of an extinct volcano in Cameroon's Oku volcanic plain.
More people drown in inland waterways than any other location in Australia. Royal Life Saving Society – Australia research shows that 255 people drowned in a lake, dam or lagoon in Australia between 1 July 2008 and 30 June 2018, with 51% of these occurring in lakes, 44% in dams and 5% in lagoons.
The Murray River remains the leading river blackspot for drowning across New South Wales (NSW), Victoria (VIC) and South Australia (SA), with the Yarra River in Melbourne (VIC), Hawkesbury River in Sydney (NSW), the Murrumbidgee River in ACT and the Swan River in Perth, Western Australia (WA) accounting for the top ...
Lake Michigan is considered the deadliest of the Great Lakes due to its unique north-south orientation, which, combined with prevailing west-to-east weather patterns, creates powerful, unpredictable, and often unseen rip currents and "structural currents" near piers and sandbars, pulling swimmers out quickly, exacerbated by cold water shock and less experienced swimmers unfamiliar with freshwater dangers. High tourism also means more people are at risk, despite fewer lifeguards, making vigilance crucial.
According to the Great Lakes Water Safety Consortium, dangerous currents and breaking waves are common in the Great Lakes, though rip currents and others found near piers are especially dangerous for swimmers and can lead to drownings.
In August 2022, ABC57 reported that at least 38 people had drowned on the lake so far that year, making Lake Michigan the most fatal of America's five Great Lakes.
Queen River, Tasmania. The Queen River, part of the King River catchment, is a minor perennial river located in the West Coast region of Tasmania, Australia. It is notable for its high level of pollution caused by mining runoff which has led the river to be uninhabitable to life.
Swimming is not advised in the Brisbane River due to the hidden dangers you may not be aware of. Strong currents and undertows may occur, especially after heavy rainfall. There are many different watercraft users in the Brisbane River including boats, ferries and canoes.
The Mary River in the Northern Territory (NT) is often cited as having the highest density of saltwater crocodiles globally, particularly around spots like Shady Camp, with estimates of up to 15 non-hatchlings per kilometer, while the East Alligator River (Kakadu NP) and the Proserpine River (Queensland) are also notorious hotspots for dense populations, especially large individuals, making them extremely crocodile-infested.
Globally, the highest drowning rates are among children 1–4 years, followed by children 5–9 years. Males are especially at risk of drowning, with twice the overall mortality rate of females. In the US, an average of 3,500 to 4,000 people drown per year. That is an average of 10 fatal drownings per day.
Australia's top three causes of death are consistently Dementia (including Alzheimer's disease), Ischaemic Heart Disease, and Chronic Lower Respiratory Diseases, though their exact order and numbers shift slightly year to year, with dementia often leading for females and heart disease for males, and lung cancer and cerebrovascular diseases also prominent in the top five.
Males are known to be at higher risk of drowning than females, particularly during adolescence and early adulthood as risk-taking behaviour becomes more apparent. The low impact nature of aquatic activity makes it an ideal form of physical activity and recreation for older people.
Lake Karachay has been described as the "most polluted spot on Earth" by the Worldwatch Institute. A satellite view of Lake Karachay.
Roopkund Lake. Located in India's Himalayan mountains is Roopkund, a small glacial lake that holds an extraordinary secret. Scattered around and beneath its waters are the remains of hundreds of individuals, a mystery that puzzled scientists and locals for decades.
Blue Lake – the world's cleanest lake. Imagine a lake whose water is so clear that you can see every stone on the bottom, even dozens of meters away. Such a place really exists! It's Blue Lake, or Rotomairewhenua, hidden in the heart of Nelson Lakes National Park, on the northern edge of New Zealand's Southern Alps.
Australia's largest terrestrial predator is the Dingo, a native canine that acts as an apex predator, managing herbivore populations and benefiting ecosystem health, though the marine saltwater crocodile is the continent's largest overall reptile predator, while the extinct Thylacoleo carnifex (marsupial lion) was Australia's largest-ever mammalian predator.
Although neonates dominated the catches, animals between 85 – 130 cm were not uncommon and this together with tag recapture data indicates that bull sharks remain in the Brisbane River from birth until approximately 140 cm when they move to a marine environment.
Look for safety signs and do not swim in rivers, estuaries, mangrove shores or deep pools. Always seek local advice in your area about crocodiles before boating, fishing and camping.
You know that saying, “Come down for air” – aka Tasmania's catchy tourism slogan? Well, you might want to take it seriously, as Hobart came out on top as the city with the lowest air pollution levels in Australia and the third lowest in the world.
The Tárcoles River is home to over 2,000 crocodiles and, as such, is considered the river with the most crocodiles per square mile. But are there any other rivers that can possibly compete with this famous river? The Nile Crocodile can grow up to 20 feet long and weigh up to 1,650 pounds!

Legend has it Lake Lanier is haunted. The perpetrators vary. Some blame spirits from the graves the Corps of Engineers never relocated in 1956. Others fault the phantoms of the twenty-seven victims who have died over the years at the lake but whose bodies were never successfully recovered.
Riptides and icy waters go against experienced swimmers. Lake Superior is too cold to swim in!
Edmund Fitzgerald was battered so intensely by Lake Superior that the 729-foot (222 m) ship split in half; her two pieces lie approximately 170 feet (52 m) apart at a depth of 88 fathoms (530 ft; 160 m). Lightfoot sings that "Superior, they said, never gives up her dead".
