New pond owner here.

Had a fishing pond constructed last August. I love in central Oklahoma and was told I had good clay to properly seal and hold water.

My pond is just shy of 3/4acre and supposed to be close 8' at deepest. We unexpectedly hit the water table at about that depth.

My question is, what should my expectation of amount of "wicking" or settling should I expect? I've seen the water go up and down and at most close to 2 1/2' deep.
I expected, based on other pond owners, my pond should have been close to full by now. I'm hoping it's not leaking, but if it is not happy with run around from pond construction company.

Appreciate any feedback.

Thanks!
