Springs, due to water table changes, both give and take. I have the same thing in a small pond. As the trees suck the ground water, the level of the water drops. Mine is about gone and I found small dead bluegills a couple of days ago.

I would plug it with good clay.

It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.
