Good question.
When you look at the larger picture, the amount that they shut down wouldn't be seen as that important. It was approximately 100 cubic metres per second. Unfortunately for us, when we first put the causeway in, we had good flow through the causeway at 900 cubic metres per second, a relatively high flow, and then it dropped quite quickly. When we saw it, it was fairly low as well.
That was a significant factor. It was roughly one-third of the drop in flow. We did not know at the time that this was going to happen, and very quickly B.C. Hydro got hold of us and let us know that they could adjust, help monitor, or do whatever. They had no intention of complicating an already difficult situation. But again, it would be something we would take into account in the future, just check with B.C. Hydro to see when they're scheduling and whether they could wait for a month.
