I just completed a pond/waterfall in my back yard (pictures to come). The total length is about 20' long and the pond is a max of 10' x 6', 3' deep. I think I fixed all of the leaks but I'm still losing about 1" of water a day. It has been hot here in KC, but I'm not sure how to tell if that is normal or I have a leak somewhere. I've pulled up rocks on both sides and don't see any water on the liner. Think it is still leaking, or will it evaporate that much? The daytime temperature has been in the low 90's.
