That is why I mentioned the GSF. The little pond is above a shallow duck pond that has GSF due to flooding events from a nearby stream. Guessing that they made it up to the artesian pond during a period of heavy rain when the overflow was running a bit heavier than normal. I did add a single LMB in the hopes that it would eat the GSF, but never saw it again. This little pond is only about 25' in diameter, but was dug 8, deep in the center.
