Now I'm starting to worry about something I've never had on my "worry list"
before. I've NEVER added anything like dechlor to my pond, and I do
partial water changes and topoffs often. The pond is about 4000 gallons,
and every time I do a skimmer/pump/filter cleaning (about every week or
maybe a little less) I let a lot of water run out of the pond. I let it go
down 4 or 5 inches at these times, and when I was installing the skimmer a
month or two ago I let a LOT more out than that. Then I fill it back up
with the hose and don't worry about it. I've never lost a fish, and the
water looks clean and clear 80% of the time. Should I be worried, or is
there enough volume in my pond to dilute the topoffs?

But would it not depend upon how Much water is being
topped off?? I think I would add some DeChlor every
other day or so- just to be sure the Chlorine wasn't poisoning
the pond.
FWIW....

I say no, because:

a) the amount of water topped off is small, per day
b) you specify clorine, and not the nastier cloramine
