That is part of the review: we've been asked to look at and to see whether we can answer that question. I would start off by noting the following. It's going to be challenging to precisely answer that. The reason is that we know the natural flow in the river is dropping anyway. For example, above and below the site we're talking about this morning, there is natural dewatering occurring. Salmon redds are being exposed naturally and there is some natural loss occurring.
The issue in Big Bar is to what extent the causeway exacerbated that, and therefore what could we identify as lost to Big Bar. That is part of the review, and I don't have a specific answer.
I can say this about pink salmon in the Fraser River: the population is at an historical high. We've had very strong returns of pink salmon to the lower Fraser River for the last decade and a half. The population from a conservation perspective, in contrast with other salmon populations, is in very good condition. That's not to justify this or to rationalize it; it's just to provide a bit of background. That particular population in the lower Fraser is doing extremely well. In fact, often we have additional fish that could be harvested based on the strength of that population.
We will be looking at trying to answer that question more precisely, but I'm unable to provide that kind of detail today.
