If I were to distill your question, I think what you're asking is whether we could have predicted what did happen would have happened. I think that's the essence of your question, whether we could have predicted that.
My response is that with the information we had at the time, we felt we took responsible measures that were designed to address the conditions we were facing and our understanding of the situation at the time. So with the information we had, based on the review I've spoken of plus the evaluations we made this year, we think we took the responsible measures required at the time.
Now, the question is, can we learn from that? Are there things we have learned from this experience that will help us next year or in the future when gravel removal is being considered once again?
We are going to do a review, as I've indicated, and based on that review and the recommendations that emerge, we will factor that into the future. But again, from our point of view, I think to the extent we could predict what happened and take it into consideration, we did.
What we found in the space of a week was that some of our assumptions did not prove to be valid and we did not get the flow we anticipated through the causeway. We made the adjustments and adjusted rapidly under the circumstances. Now we have to evaluate what happened and determine what we should do in the future.
