When water (Hydro) falls down through the turbine blades of an electricity generator, the blades are made to spin. The blades are connected to a shaft, which is connected at the upper end to the armature of a large generator, which produces electricity. Most, if not all, hydroelectricity is produced in tall dams on rivers. Examples include Hoover Dam in Nevada, and Grand Coulee Dam in Washington. The electricity produced in dams is no different from electricity produced in other ways.
"The state of Washington leads the nation in hydroelectricity... About 87 percent of the electricity made in Washington state is produced by hydroelectric facilities" http://www.energyquest.ca.gov/story/chapter12.html
It all depends on how big the dam was, how much it cost, and how much electricity it produced. Or, in the case of Hoover Dam, the profits of tourism. It can take up to 5 years, but it typically will take around 2-3.
The Hoover Dam generates 4.2 billion kW/h of electricity each year. The United States produced about 4.151 trillion kW/h of electricity in 2010. This means the Hoover Dam produced about .101% of the total US power.

Water behind a dam falls down through giant turbines which are connected to great generators, which make electricity because they are turning.
6000000000 volts
It produces 12000kilo
Hydro-power is electricity created when water is forced by gravity from a dam and through turbines. The spinning turbines turn generators, and electricity is produced.
When the water here is like a dam, water weight creates pressure on water depth. The term refers to the pressure of the hydraulic turbine driven generators and electricity is produced and run. The water flow of electricity is produced. Electricity can be generated from tidal water. Hydraulic fluid power is used.
When electricity is produced by having falling water directed into turbines.which in turn drive the generators at the base of a dam. These are Hydo-power plants
The Grand Coulee Dam.
