My understanding on that one is the definition went back to the twenties. There were a number of changes, as I said, with respect to the fish passage sections. One of them was it actually referred to the types of obstructions that we'd be dealing with: logs were mentioned, and a number of other pieces were mentioned. Since the twenties there are way more obstructions than that. We've just modernized it to cover any obstruction to fish passage. That's basically what the intent was.
I think the definition went back to the twenties. Now I'm going to look to make sure I'm right: yes.
