The World’s 25 Largest Lakes, Side by Side

In many parts of the world, you don’t have to look very far to find a lake.

According to satellite data, there are roughly 100 million lakes larger than one hectare (2.47 acres) to be found globally. The largest lakes, which rival the size of entire nations, are more of a rarity.

One might expect the world’s largest lakes to be very alike, but from depth to saline content, their properties can be quite different. As well, the ranking of the world’s largest lakes is far from static, as human activity can turn a massive body of water into a desert within a single generation.

Today’s graphic – created using the fantastic online tool, Slap It On A Map! – uses the Great Lakes region as a point of comparison for the largest 25 lakes, by area. This is particularly useful in comparing the scale of lakes that are located in disparate parts of the globe.

The Greatest Lakes

The largest lake in the world by a long shot is the Caspian Sea – a name that hints at a past when it was contiguous with the ocean around 11 million years ago. This massive saline lake, which is nearly the same size as Japan, borders five countries: Kazakhstan, Russia, Turkmenistan, Azerbaijan, and Iran. An estimated 48 billion barrels of oil lay beneath the surface of the basin.

The five Great Lakes, which run along the Canada–U.S. border, form one of the largest collections of fresh water on Earth. This interconnected series of lakes represents around 20% of the world’s fresh water and the region supports over 100 million people, roughly equal to one-third of the Canada–U.S. population.

Amazingly, a single lake holds as much fresh water as all the Great Lakes combined – Lake Baikal. This rift lake in Siberia has a maximum depth of 5,371ft (1,637m). For comparison, the largest of the Great Lakes (Lake Superior) is only 25% as deep, with a maximum depth of 1,333ft (406m). Lake Baikal is unique in a number of other ways too. It is the world’s oldest, coldest lake, and around 80% of its animal species are endemic (not found anywhere else).

The Great Lakes World Tour

For people living in Canada and the U.S., the shape and relative size of the Great Lakes system may be quite familiar. This makes the Great Lakes a fantastic point of comparison to help put the size of other world locations into perspective. To this end, we begin our Great Lakes World Tour.

First, the image below shows how the Great Lakes system would look if it was located in India.

Distortions on commonly used maps can downplay the size of India compared to more northern nations. This view of the Great Lakes can help put India’s true size into perspective.

Next, we look at the Great Lakes overlaid within Central Europe.

In the context of Europe, the lakes are so large that they extend from the Netherlands over to Slovakia. Lake Superior’s surface area of 31,700 mi2 (82,000 km2), is similar in size to Austria. Here’s are the five Great Lakes and European countries of equivalent size:

Lastly, here is a look at the Great Lakes in Southern Australia. Australia is the world’s 6th largest country, so the Great Lakes only occupy one corner of its land mass.

Australia’s lack of glacial history means that there are few permanent freshwater lakes in the country. Many of the country’s largest lakes only fill up during periods of excessive rainfall.

Shrinking out of the rankings

Not far from the world’s largest lake, straddling the border between Kazakhstan and Uzbekistan, lay the sand dunes of the Aralkum Desert. In the not so distant past, this harsh environment was actually the bed of one of the largest lakes in the world – the Aral Sea.

Aral Sea receding 1960 2020

For reasons both climatic and anthropogenic, the Aral Sea began receding in the 1960s. This dramatic change in surface area took the Aral Sea from the fourth largest lake on Earth to not even ranking in the top 50. Researchers note that the size of the lake has fluctuated a lot over history, but through the lens of modern history these recent changes happened rapidly, leaving local economies devastated and former shoreside towns landlocked.

Lake Chad, in Saharan Africa, and Lake Urmia, in Iran, both face similar challenges, shrinking dramatically in recent decades.

How we work to reverse damage and avoid ecosystem collapse in vulnerable lakes will have a big influence on how the top 25 list may look in future years.

The Rise in America’s Billion-Dollar Extreme Weather Disasters

From tropical cyclones to severe storms, the number of extreme weather disasters with losses exceeding $1 billion has climbed over time.

A bar chart showing rising U.S. extreme weather disasters for each decade since the 1980s, with the view cut off part way through the 2010s.

The Rise in U.S. Billion-Dollar Extreme Weather Disasters

Since 1980, there have been 383 extreme weather or climate disasters where the damages reached at least $1 billion. In total, these disasters have cost more than $2.7 trillion.

Created in partnership with the National Public Utilities Council, this chart shows how these disasters have been increasing with each passing decade.

A Growing Concern

The U.S. National Oceanic and Atmospheric Administration (NOAA) tracks each disaster and estimates the cost based on factors like physical damages and time losses such as business interruption. They adjust all costs by the Consumer Price Index to account for inflation.

DecadeTotal No. of EventsTotal Inflation-Adjusted Cost
1980s33$216B
1990s57$330B
2000s67$611B
2010s131$978B
2020s*95$568B

* Data is as of May 8, 2024.

Both the number and cost of extreme weather disasters has grown over time. In fact, not even halfway through the 2020s the number of disasters is over 70% of those seen during the entire 2010s. 

Severe storms have been the most common, accounting for half of all billion-dollar disasters since 1980. In terms of costs, tropical cyclones have caused the lion’s share—more than 50% of the total. Hurricane Katrina, which made landfall in 2005, remains the most expensive single event with $199 billion in inflation-adjusted costs.

Electricity and Extreme Weather Disasters

With severe storms and other disasters rising, the electricity people rely on is significantly impacted. For instance, droughts have been associated with a decline in hydropower, which is an important source of U.S. renewable electricity generation

Disasters can also lead to significant costs for utility companies. Hawaii Electric faces $5 billion in potential damages claims for the 2023 wildfire, which is nearly eight times its insurance coverage. Lawsuits accuse the company of negligence in maintaining its infrastructure, such as failing to strengthen power poles to withstand high winds. 

Given that the utilities industry is facing the highest risk from extreme weather and climate disasters, some companies have begun to prepare for such events. This means taking steps like burying power lines, increasing insurance coverage, and upgrading infrastructure.
