The waterfalls are artificial. In other words, Idaho Falls Power can control the flow of water over the falls based on the power needs of the region. 80% of the electrical needs of the city is hydroelectric. The waterfalls provide the electricity via hydroelectricty. If the city is flush with electricity, the waterfalls dump less. If more is needed, more water pours.
Thank you very much. I knew they generated power, I just had NEVER seen NO water. 😁
