1 Basic Function of Water Reservoirs

A water reservoir is an enclosed area for the storage of water to be used at a later date. It can also serve to catch floods to protect valleys downstream of it, to establish an aquatic environment, or to change the properties of the water. A reservoir can be created by building a dam across a valley, or by using natural or man-made depressions.
