The Water Makes a Comeback

Looking back, 2008 can be remembered as a major comeback year for Lake Superior’s water levels. In late summer, the lake was 17 inches higher than at the same time the previous year, when Lake Superior set new record-low levels in August and September because of a drought across the region.

The lake benefited from above-average precipitation. As 2009 got under way, the U.S. Army Corps of Engineers continued to be encouraging when it reported that precipitation across the Great Lakes basin “as a whole was well above average for the month of December.” Lake Superior’s water level in early January was 4 inches higher than at the same time in 2008 (but still 6 inches below the long-term monthly average for January).

The prediction for 2009? The Corps reported that “through June, lakes Superior and Michigan-Huron are predicted to remain above their levels of a year ago.”
