Scott,
Of course, but until that cube finishes melting you will have LESS water in the glass and a lower water line. Not enough to be seen by the naked eye, but it is still there.

Roughly 11% of that cube will be sticking out of the water due to the decrease in density of the ice as compared to water. That 11% will not count as part of the water line until it has melted. Most of it is offset by the increase in volume (9%) of the ice over water, but not all.

When you put that ice cube in the glass your water line will be a little bit lower until your ice cube melts.
