Question: What do wicket gates do in hydroelectric dams?

Answer: Hydroelectric dam Wicket gates typically surround the turbine from all sides and are composed of of metal slats that pivot at the middle. When closed the wicket gates prevent water from flowing through the turbine which allows access for maintenance. By opening the gates water is allowed to flow through the turbine generating electricity. Adjusting how far the gates are opened is how dam operators control the amount of electricity generation.
