List Of Lakes By Depth - Deepest Lake In The World

This page lists the world's deepest lakes.

Lakes ranked by maximum depth

This list contains all lakes whose maximum depth is reliably known to exceed 400 metres (1,300 ft)

Geologically, the Caspian Sea, like the Black and Mediterranean seas, is a remnant of the ancient Tethys Ocean. The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt lake.

Lakes ranked by mean depth

Mean depth can be a more useful indicator than maximum depth for many ecological purposes. Unfortunately, accurate mean depth figures are only available for well-studied lakes, as they must be calculated by dividing the lake's volume by its surface area. A reliable volume figure requires a bathymetric survey. Therefore, mean depth figures are not available for many deep lakes in remote locations.

The Caspian Sea ranks much further down the list on mean depth, as it has a large continental shelf (significantly larger than the oceanic basin that contains its greatest depths).
