Matt:

I have a groundwater pond, and at times of the year I can hit water at 18".

But, my pond typically will fluctuate between 4' to 6' in depth, and currently it is sitting close to 5' low.......

I dug mine to 21' deep and don't regret it one bit. I've gone thru a winter with 12' of water in it........
