 How long ago did that change? I don't remember exactly when it came out. A few years? Yeah, five, ten years maybe. So, Scott, I know that's been a big push lately is updating the infrastructure of dams or removing dams, and a lot of that is for fish movements and things like that. When you think about these events that are taking place right now, obviously an event like this is being taken into account when you talk about removing dams, right?
