It would be more correct do define own symbol set than to redefine the
default symbol (it has the same result, but redefining the default doesn't
allow to switch among various symbol sets). So the correct solution is:

-----------------------------
color map-fg 50
symbol-hide group all
symbol-show area water
symbol-assign area water MY

code metapost
  def a_water_MY (expr p) =
    T:=identity;
    thfill p withcolor (0.1, 0.2, 0.8);
  enddef;
  initsymbol("a_water_MY");
-----------------------------

Now you may use the symbol-assign command to switch among all predefined
symbol sets and the new set MY.
