I think a small hydropower plant was added to the dam some years ago. I guess that might be used as reason and justification to keep the dam in place. But I think it makes sense to remove the dam if and when the steam plant is retired. I was surprised to learn that it stopped using local coal over 20 years ago and is burning coal imported from Utah. That doesn't appear to make economic sense. Most coal fired generation occurs near where the coal is mined, since it costs a lot of money to transport coal.
