Largest Lake in the World

There are a few different ways to define the world’s largest lake. Are we interested in the lake with the largest surface area? Or, the lake with the greatest water volume? And, should we consider the salt water seas in our comparison?

“Which lake is the World’s largest?” is not a simple question to answer. So, we will explore all of these questions and you will then have all of the many possible answers.

World’s Largest Lake (by volume):

The salty Caspian Sea is the world’s largest land-locked body of water. It contains approximately 18,900 cubic miles of water (78,700 cubic kilometers).

Lake Baikal is the world’s largest freshwater lake in terms of volume. It contains about 5521 cubic miles of water (23,000 cubic kilometers), or approximately 20% of Earth’s fresh surface water. This is a volume of water approximately equivalent to all five of the North American Great Lakes combined.

    Factually Lake Michigan is the largest lake in the US NOT Superior, as approx 1/2 of Superior is in Canada. Also, Huron and Michigan are technically considered a single body of water and thus comprise the Largest Surface Area Body of Freshwater in the World. Thank You.

    Agreed. Lake Baikal is one of the deepest and the largest freshwater lake amongst all Lakes in the world , However it contains less than one third of the water as the Caspian Sea.

    Looking at some of the pictures of these lakes on Google images, they look fantastic especially Biakal. Wonder if these places are open to Lakes and mountains holidays
