I would expect the opposite - the elevation of the water surface above sea
level. It appears that Google Earth does it this way (e.g. Lake Arrowhead ~
34.258476, -117.182861).
If you look at other maps e.g. here:
Since water levels, can fluctuate substantially both seasonally and
annually, I'm not sure of the benefit of the ele=* tag on bodies of
water, nor on contours since this is something you'd use DEM
information/files for.
*Maybe* I'd use them on glaciers, but only peaks, otherwise you just
end up

on some it is
eg Lake Cargelligo is almost flat at the bottom - I've seen it empty
