Why is any correction for the lake height needed? The altitude of an object above the
horizon (corrected for the observers height above water level) should be the same.

If you know the lake height above (or below) sea level, celestial navigation
works just fine.

Some lakes are seriously large enough that potato navigation really won't
work. Check out Lakes Huron, Michigan, and the grand daddy of them all,
Superior!

I think you might be able to make a correction for your elevation. I
also am assuming and having never been much of a laker, that dead
reckoning would work. Can't be too long before you hit shore there no
matter where you are hey?

Just wondering...on the oceans, navigators use a sextant for out of sight
of
land navigation. How is it done on the Great Lakes where they're not
operating at sea level? Of course, I'm talking about the absenceof
electronics. Anyone know of any literature on this?
