Recently had a pond installed and I have some Koi fish in the pond. I am planning on running the pond year round. I live in central Pa. I believe it is zone 7. I was out checking the pond and don’t know why but decided to check and see just how deep the deepest part of the pond was. I was suprised to find out that the depth was only 16 inches at the deepest point. I know everything I read says a min. of 24 inches is required for this area. What will happen if I leave as as and run year round. Will the fish freeze and die. I have contacted the pond installer and waiting for him to contact me back. The pond is an 8 by 11 Auqascape kit. Thanks!

The recommended depth for northern ponds is 24 inches. It all depends on cold it gets and how deep your frost line is. I would be concerned about Koi in a 16″ deep pond if you get a severe winter.
