The short answer is that we are looking at the trends. We started monitoring in 1908. The trends have varied. It is a bit different, as you walk through the Great Lakes, but we actually hit a record low in 2013, if you remember January 2013 in Michigan-Huron, and that has rebounded. When looking at the Great Lakes, we work closely, through the IJC, with the U.S. in monitoring; we do it together. The models are being used to look at trends.
The biggest significant factor for water levels is precipitation. The amount of rain and snow that we get is what most affects the actual water levels. What the trends are I think depends on where you are in the Great Lakes. Right now, in the last two years, there has been a lot of snow and rain, so the water levels have gone up in Michigan-Huron, but they are lower in the southern part. So it varies over time.
