Expert Answer:

Water collecting on the ground or in a stream, river, lake, wetland, or ocean is called surface water, as opposed to groundwater or atmospheric water.

Surface water is naturally replenished by precipitation and naturally lost through discharge to evaporation, and sub-surface seepage into the groundwater.

The main uses of surface water include drinking-water and other public uses, irrigation uses, and for use by the thermoelectric-power industry to cool electicity-generating equipment. The majority of water used for thermoelectric power, public supply, irrigation, mining, and industrial purposes came from surface-water sources.
