Great Lakes water levels remain above average
The Army Corps of Engineers reports in July that each of the Great Lakes remains above their respective long term July average and are expected to remain above average for the rest of the month. All of the lakes except Lakes Erie and Ontario have risen over the last 30 days with Lake Superior being 2 inches above its level a month ago. Lakes Michigan-Huron and St. Clair are 2 and 3 inches above their level a month ago, respectively, while Lake Ontario is 6 inches lower than last month.
As the summer progresses, the Great Lakes system is expected to see the lakes begin their seasonal declines. Lake Superior is expected to remain about the same over the next month while Lakes Michigan-Huron, St. Clair, Erie and Ontario are expected to decline 1, 3, 5, and 8 inches respectively over the next month.
