Thanks to you all!.

The pond is not a liner pond. It is an old ski boat.. It holds water up to
the seam line between the top and bottom sections. That line is two inches
above ground level.. There's not a fountain or spitter. The kiddy pool
does overflow when it rains. I'm thinking maybe the plants in it block the
outlet back into the pond when it rains, so that the only place for the
water to go is over the top of the kiddy pool. . Four inches seems like a
pretty big drop, but I cannot find any other explanation. Probably we need
a bigger veggie filter kiddy pool or an additional outlet from it back to
the pond. Do you think that would help?

This may seem simplistic, but walk around the edge of the pond and/or kiddie
pool barefoot until you find the softest, mushiest place. That is most likely
where your water is going, and should give you a clue as to where to look for
overflow, leak, etc.
