Lake basins and the bodies of water they contain. A lake basin is a relatively closed natural depression on the surface that can store water. The source of lake water is precipitation, surface runoff, groundwater, and some come from ice and snow meltwater.

The consumption of lake water is mainly evaporation, seepage, excretion and development and utilization.

The total area of ​​lakes on the earth is 2.7 million square kilometers, accounting for 1.8% of the land area. There are 35 lakes with an area of ​​more than 5,000 square kilometers.
