What are the steps for creating hydroelectric power? river water enters a dam through channels. the channels are connected to a transformer, which turns a generator, producing electricity. the water is then transported through turbines to wastewater canals. river water stored in a reservoir flows down a channel in a dam, turning a turbine as it passes. the turbine is connected to a generator that produces electricity, and then the water continues downstreamriver water stored in a reservoir flows through a turbine and into a channel in a dam. at the end of the channel, the water turns a generator, which produces electricity; then the water flows back upstream. river water enters a dam through a generator. the movement of the water through a generator produces electricity. then the water flows out the dam through turbines into a reservoir.
