S252102. I had rock all through the clay when we dug our pond. It definitely added to the stress. So far so good. I've got a small leak, I guess. Losing 1/4" a day, if I could get any rain in NE Missouri, I wouldn't care at all. I sure don't remember seeing many dry ponds around Chillicothe. I will bet that yours will be fine. This weeeknd is going to be crazy cold. I was going to go quail hunting, but I hate to bust up covies, when it's in single digits.
TJ, your advice and recommendations have helped me immensely.. Don't stop! Ha!

9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
