Nice idea - I think you may have something there, if only a little more
detail can be added.

Only initial drawback I can see is the way the detailed contours would
change as the years/floods etc go by. Now if weed & snags could be
overlaid

Good idea. I've just had a play around with it & found another rough & ready
way to do that.
Select the 'map' in Excel & copy it. Now paste it as an image into whatever
image editor you've got. I use Paintshop Pro, which supports image layers -
meaning I can place the map image in one layer & then draw/paint the
additional features (snags etc) in another. Should the contours change
dramatically (& I don't reckon that'd be particularly likely on a lake!) the
new depth measurements could be used to generate a new Excel map whuch could
then be copied as above & used to replace the map layer in the graphic

Alternatively I could just get out more :-)
