Who's guessing here? I'll quote you again, "> Just a guess.
landuse=reservoir overrules natural water."  My hypothesis is based on
the experience of tagging several reservoirs exactly like this without
any problems.  The only difference is that this one involves a greater
number of nodes and took several minutes to upload.

Anyway, the tags are correct.  It's a lake, so it's tagged
natural=water.  It's a reservoir -- an area of land (territory) used
to store water -- so it's tagged landuse=reservoir.  The wiki page for
each tag indicates that the tag is correct for the situation, and I
don't see a problem with redundant tagging.  If the renderer gets it
wrong because of the way it's tagged, then the renderer needs to be
fixed, not the tags.  But I'm confident that that's not even the
problem here.
