I think the ultimate goal would be to clear it enough so that it's a natural passageway for the fish, so that it's not something that we have to continually monitor or maintain. Barring that, we will continue to make sure that there is a natural-like fish passageway there for the salmon to get through, as well as the Whooshh system this year, in order to help make sure that we get as many through as possible.
I think the primary goal ultimately would be to clear it enough so that we don't have to maintain it and we don't have to be concerned about it. We'll continue to work toward that, but in the meantime we are making sure there are measures in place to get the fish through.
