About hydropower generation


The energy in water falling 60 feet is used to make electricity.

  1. The falling water spins the turbine.
  2. The generator converts spinning motion into electricity.
  3. Transformers raise the voltage of the electricity so less power is lost on the power line.
  4. The switch yard directs power onto different power lines. Fish passage guides migrating fish safely around the dam.
  5. The fish collection channel guides adult fish migrating upstream to the fish ladder.
