The water level of Lakes Michigan and Huron (at some level) is up 5″ in the last month – unchanged from one year ago – and 14″ above the late May average. The level of Lake Superior is up 6″ in the last month, up 4″ year-to-year and is now 10″ above the century May average. The water level of Lake Erie is up 8″ in the last month, up 9″ in the last year and is now 23″ above the long-term May average. Erie is only 4″ below the record high level set in 1986.

Lake Ontario is the big story – it continues to be at an all-time record level. Ontario is up a whopping 14″ in the last month, up 32″ year-to-year and is 33″ above the average level for late May – it’s 5″ higher than it has ever been in late May. Obviously, this is causing significant beach erosion and some flooding, which is compounded when strong winds create large waves that crash against the shore. In some areas, there is no beach left, with the water up into the grass or bluff.

Lake St. Clair is up 6″ in the last month, up 6″ in the last year and is now 20″ above the century average level.
