Quickly, on the flow, from the time the causeway was put in to the day we took it out, the flow actually dropped by about one-third. So on-site it dropped quite a bit, and that's why we reacted very quickly.
On the monitoring, simply put, it's a condition of the work that day-to-day monitoring is mandatory. In addition to that, I went up four times, and I had technical people up there as well, and other private citizens were doing a pretty good job of monitoring and keeping pictures and such as well. So there was a lot of monitoring.
