As I mentioned, it's a challenge. We have Mother Nature, who is playing a serious role in this project.
I believe that the permanent solution.... I rely on the professionals who have been giving us the ideas here, and I believe that the fishways can be a solution, but I also want to make sure that we don't forget about that rock recovery, because ultimately that rock recovery is going to be fundamental to a long-term solution here. There were 75,000 cubic metres on the floor of the river, and there's still a lot there. I don't want to see that rock recovery taken off the table, but yes, a permanent solution would be the fishways, and we're relying on that.
