The purpose of dams in a hydroelectric station is to create a "head" of water. As the water rises the difference between the top of the water level and the outlet creates water pressure that is used to turn turbines that generate electricity. The dam also concurrently creates an energy storage potential that can be used as long as there is water in the dam (with diminishing production) even if the water stops flowing in the upper part of the river (due to drought and no rain or too many people taking water from the river) In some small scale hydroelectric may not use dams but tap into streams at a higher level than the outlet or may simply use the flow to turn the turbine and the generator.
