Lake Superior may set record high in 2018; Sea Grant, U.S. Army Corps of Engineers to discuss possible levels, impacts.

Lake Superior water levels are high—really high. Current levels are within just a few inches of the all-time monthly high for March, which was set back in 1986. And predictions for May, June and July set a significant probability levels could reach or even exceed the all-time monthly high for those months. The Great Lakes in general had a significant period of lake water levels being well below average in the mid-1990s until about 5 years ago. Now water levels are higher than many people have seen in their lifetime.

The U.S. Army Corps of Engineers (USACE) has been tracking lake levels with scientifically valid data for more than 100 years. The USACE predicts lake level changes with a “6-month probability” forecast, which is updated every month.

What will be the impact of higher water levels?

In partnership with Michigan Sea Grant and Michigan State University Extension, the U.S. Army Corps of Engineers Detroit District Office will discuss the changing Lake Superior water levels. The presentations are free and open to all. Coastal home and property owners, city and township government officials, boaters and marina owners, management agencies, regional planners, and anyone who enjoys recreating along the coast of Lake Superior will find the topics particularly relevant.

Dr. Lauren Fry, who leads the water level forecasting mission at the Detroit District Office of Great Lakes Hydraulics and Hydrology, will discuss what to expect in terms of lake levels over the next few months and the science that goes into determining Great Lake Water levels.

Michigan Sea Grant will provide materials and handouts to help understand what the impact might be on Lake Superior coastlines and how to prepare for the fact that lake levels change over time. A question and answer time will follow the presentations allowing the public to gain valuable insight on how changing water levels may affect them.
