I sail on Lake Michigan, and due to the large size of the lake, there is a true horizon. However, the lake is approximately 577 feet above sea level. I believe this means that the horizon is slightly farther away than it would be at sea level.

Should one use a correction factor for sights taken on Lake Michigan or is the difference insignificant?

No, in this case no special corrections are required. Just measure eye height from eye level to water level and use that for HE in the normal procedures.
