Google Earth: Elevation of water?

As I move the hand pointer across a lake, the displayed data for
'Elevation' plainly varies, so I assume it must be the altitude above
sea level of the ground at that point? It plainly cannot be the
surface!

For example, I'm looking at Ardingly Lake ('ardingly, sussex, uk').
Other mapping programs I use such as Memory Map etc, tell me its
altitude is 174 ft, yet GE shows wide variations throughout.

Yet, inconsistently, the English Channel is correctly shown as 0 ft
throughout, as is the Atlantic Ocean (give or take a foot or two).

Anyone know what's going on here please?
