Selective water withdrawal refers to withdrawing water from a dam lake, which varies in temperature and turbidity depending on its depth, for different purposes. For example, water on the surface of a dam lake is warmed by the sun, so only this water is withdrawn and used for agricultural purposes, such as growing rice.

Selective intake facilities are attached to the embankment or installed in the dam lake, and water from each layer is taken from these facilities and discharged downstream. Since there are both deep and surface layers, most selective intake facilities are tower-like and equipped with multi-stage gates.
