Are Great Lakes water levels headed up in 2018?

Fall of 2017 was a very wet season in the Great Lakes region. According to the US Army Corps of Engineers, basin-wide precipitation was well above normal for all of the Great Lakes during October 2017. In fact, these estimates put the monthly precipitation at 118 percent of average for Lake Superior, 161 percent of average for Lakes Michigan/Huron, 107 percent of average for Lake Erie, and 170 percent  of average for Lake Ontario. Accordingly, while the lakes generally continue seasonal decline into winter, the rate of this decline has been much more gradual.
