Eric, when you hit sand, it's like having a bucket with a hole in it.

Trying to figure out how to explain this. Get a bucket and put a small hole in it. Put some sand in it. Put the bucket in a washtub or something. Pour water into the washtub. You will see the water rise in the bucket and equalize to the level in the tub. Now suck some of the water out of the tub and you will see the water level decrease out of the bucket into the tub. The same thing will happen if you put sand in both the bucket and tub to find an equal level. Water always seeks it's own level. A spring and/or aquifer can both give and take.

Another way of looking at it is to dig a hole next to and deeper than the well. Use a pump and empty the water from the new hole. The water previously contained at the bottom of the well will flow into the newly created void.

If you dig the pond deeper than the water bearing sand and hit good clay, the water in the aquifer will fill the new area below the aquifer and keep the pond full at the level below the sand. However, you won't know until you dig just how deep the aquifer/sand goes.

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.
