Just to add to that, as the minister said, we're doing enhancement, habitat restoration and fisheries management measures that we instituted last summer, and we're looking at more this summer.
We're working very hard on all fronts. However, the reality is we won't know what the result of the rock-blasting work that we did over the winter will actually be until the summer, when we can actually observe the fish when they come back and see if they're getting over. Even then there will be a bit of a lag, because we have to count how many actually are able to get over, and it takes a little while to get that information.
That is why we need to have plan B, plan C and plan D all ready to go.
As I said, we have a very strong commitment to ensuring that fish can ultimately get over that barrier.
