November 17 Water Levels Report
From a month ago water levels on Lake Michigan-Huron are unchanged, Lakes Superior, St. Clair, and Erie are 4, 1 & 2 inches lower respectively, and Lake Ontario is up 2 inches. Lakes Superior, Michigan-Huron, St. Clair, Erie and Ontario are 1, 16, 9, 4 and 17 inches, respectively, above their levels of a year ago. In a month’s time all the Lakes are projected to be 3 to 4 inches lower.
Outflows from Lake Superior into the St. Mary’s River and Lake Michigan-Huron’s outflow into the St. Clair River are predicted to be above average for November. Lake St. Clair’s outflow through the Detroit River and Lake Erie’s outflow through the Niagara River are also forecasted to be above average in November. In addition, Lake Ontario’s outflow through the St. Lawrence River is projected to be above average for November.
High water levels and potentially record high water levels are expected to persist for at least the next six months, so flood prone areas are expected to remain vulnerable.
