I have heard that there is a call for a greater than usual volume of Lake effect snowfall this year due to the higher than usual Lake temperature.

We keep our boat in Hamilton, Ontario, and the water level at the fixed docks at the Royal Hamilton Yacht Club is so low now that I have to sit on my butt on the dock with my legs dangling in space before a gingerly lower myself on to the deck of Trillium now several feet below dock level. I can't see how putting baffles in the St. Clair River is going to improve the water level on Lake Ontario. There seems to be something more at work here than water flow through the St. Clair River. It probably has to do more with lack of snow fall and snow build up in the winter with resulting reduced run off in the spring, as well as changes in precipitation generally. Global warming (or Climate Change) perhaps? I don't have an answer, but this does seem to be a problem facing the whole Great Lakes, not just the Upper Lakes.
