June 22 Water Levels Report
Persistent wet conditions and high outflows have continued to contribute to exceptionally high lake levels. The water levels for all of the lakes are above their highest monthly average record for June, above last month by 2 to 6 inches, and above last year’s levels by 10 to 15 inches, except for Lake Ontario, which is expected to be 28 inches above its level from last year. Lakes Superior, St. Clair, Erie, and Ontario’s levels are 3 to 5 inches above their record high June average level, while Lake Michigan-Huron is 1 inch above its record high June average level. In the coming month, Lakes Superior and Michigan-Huron are expected to continue their seasonal rise and rise by 2 inches and 1 inch, respectively. Lakes St. Clair, Erie, and Ontario are forecasted to decline by 1, 3, and 7 inches, respectively.
Outflows from Lake Superior through the St. Mary’s River, and Lake Michigan-Huron’s outflow into the St. Clair River, are projected to be above average in June. Lake St. Clair’s outflow through the Detroit River is also forecasted to be above average.
