How many lakes are on Earth?

A plain-language explanation of why global lake counts change depending on minimum size, source dataset, and whether reservoirs or temporary waters are included.

How many lakes are on Earth?

There is no single permanent lake count because every dataset has to choose a minimum size and a definition. A tiny seasonal pond, a reservoir, a crater lake, and an inland sea may not all be counted the same way.

This guide explains the difference between scientific lake inventories, public map records, and everyday language so visitors understand why numbers can look different from source to source.

LakesOnEarth should always state the dataset, threshold, and definition behind any global count before treating that number as finished.
