November 16th Water Levels
A dry second week of November across the Great Lakes basin has helped offset the wet start to the month, but, even with below average precipitation last week, the basin as a whole has still received 25% more than average month to date precipitation.
Lake Superior’s water declined an inch over the last month as Lake Michigan-Huron declined 2 inches. When compared to their levels a year ago, Lake Michigan-Huron is 1 inch higher than it was a year ago and is expected to decline a further 2 inches over the next month.
Lake Superior’s outflow through the St. Mary’s River is predicted to be above average in November. Lake Michigan-Huron’s outflow into the St. Clair River and the outflow of Lake St. Clair through the Detroit River are projected to be above average.
