Lakes Michigan and Huron almost set records for low water levels in October, as the long-term effects of this summer’s drought are still being felt. 

From the Detroit Free Press

“The U.S. Army Corps of Engineers, which tracks Great Lakes ups and downs, recorded Michigan-Huron at 576.6 feet above sea level for October. That’s an inch-and-a-half above the lowest point for that month since the agency began keeping records in 1918, and about 6 inches above the all-time low recorded in March 1964.

Michigan and Huron are considered one lake from a hydrological perspective because they have the same surface level and are connected at their northern ends by the 5-mile-wide Straits of Mackinac.”
