Lake Superior typically reaches its annual low in early April, and its highest level in late September.
The November precipitation in the Lake Superior basin was 81% of the long term monthly average. Outflow through the Sault was 78% of normal.
Despite the below normal precipitation and discharge from Superior, the lower Great Lakes are recovering. Lakes Huron and Michigan actually rose almost 3" in November. They normally decline about 3" in that month. Nonetheless, those lakes are still about 19" below normal and down about 2" from a year ago.
