A hydro-dam is an amazing structure that makes electricity from water!
Firstly you build a dam to block the river. Water then builds up behind the dam. This is called the reservoir.
Water then goes through the intake. After it goes through the intake it goes down the penstock.Water then hits the turbine very fast and spins very fast
which makes electricity which is stored in the generator.
The electricity then travels through the power lines to houses and cities.
