I'll get back to the fish ladder thing in a second. The next question I have for you is about hydrology.
Did you have a before-and-after picture of the hydrology of the river after you removed, I believe, 14,000 cubic metres of rock, which I think was a number that you said exceeded the original expectation?
Obviously, from an engineering perspective, you would have looked at the hydrology to maximize.... Whether it's blasting out the East Toe or the larger chunks of rock, did you strategically go after specific areas of the river, or did you just go with the easiest stuff to get at? Did you have a before picture of the hydrology, and an after picture? Was there a target of the hydrology of the current you were looking for in order to enable fish passage, and were you able to achieve that, if that was indeed what you were trying to do?
