Dams [dămz]
Barriers constructed to hold back water and raise its level in order to create a reservoir.

A dam, whether it is big or small, is a plug in a stream of water. Humans first built dams for irrigation. Now we use dams for many more purposes. We use them to generate electricity, to control floods, for recreation, and to store water for later use. Scientists play an important role in designing dams and dealing with their environmental impacts.
