What happens to a quarry during a 5 year drought? Depending on the depth of the water table relative to the pond depth, maybe nothing. However, I suspect that the natural springs reversed their flow and took rather than gave.

Looking at only these pictures, there is no way of knowing about this BOW during the drought. The aquifer could either be pretty extensive or limited to that area.

Not knowing the actual history, it may also be that this thing dried up or was pumped dry and further mining could have deepened it until the springs were hit.

During a "normal" time of rainfall, you would have a tough time pumping this place dry. Finding aquifers/ground water that cannot be pumped out has always been the bane of mining.

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.
