As much as I hate to be a wet blanket...

According to Madge and Burns (Waterfowl 1988):
Pink-footed Goose 60-75cm (24-30in)
Gr White-fronted Goose 66-86cm (26-34in)
Snow Goose 65-84cm (26-33in)

This is considerable overlap and given the difficulties associated
with judging size in the field probably not significant enough
to be dependable.

I suspect that you may have seen a hatch-year White-fronted Goose.
These do not have the "white front" or the speckled belly. I fact
they look pretty much like Pink-footed Geese with orange legs.

This doesn't mean somebody shouldn't go check the bird out. Of course
given that it's in a county park pond, it may actually be a Pink-
footed Goose, but its origin would be questionable.
