Is the spring above or below the pond water level? If under, the spring will either give or take water depending on the water table. They can be tricky. If above, is it a flowing or seep spring? I have one small pond that is actually a water level pond depending on how much rain I get and how much the big oak trees around it take. The pigs like to get in it and roll around. By August, it is generally dry and a muddy eyesore.

If it is above water level, good luck on drying it out and expanding.

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.
