How Deep Should a Pond Be? (Pond Depth Explained)

People chase the “perfect” answer to this question all the time, but the truth is there isn’t one.
As an industry standard, we like to say that an in-ground pond needs to be at least two feet deep. That’s our minimum as professionals.
Is it a rule? No, it’s not a rule. I’ve seen plenty of homeowners dig ponds shallower than that. I just don’t consider that to be a professional installation.
