November 10 Water Levels Report
From a month ago, water levels on Lake Ontario are unchanged and Lakes Superior, Michigan-Huron, St. Clair, and Erie are 1, 1, 4 & 4 inches lower respectively. The lakes are 2 to 18 inches higher than they were at this time last year. In a month’s time, Lakes Superior, Michigan-Huron, St. Clair and Erie are projected to be 2 to 3 inches lower, while Lake Ontario is forecasted to fall 5 inches.
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.
