Drain the pond and add a 2' clay liner to the entire bowl that is packed with a sheep's foot roller in 6" lifts, unless you can identify where all the leaks are with confidence. If the dam has any sand in the core, then a new core is needed as well. I know this is not what you want to hear, but throwing good money after bad is not wise. I feel your pain. I went through 4 contractors on my second pond (the last 2 to fix problems created by the first 2), but the resulting pond is as tight as a drum. I got lucky on my first pond that was built by a great pond guy, but he retired before the second pond went in. I built my 3rd pond myself. It is surprising how hard it is to find a pond digger that knows how to build a pond. I will say that some excavators that I have talked to struggle with the concepts while other think they can defy physics by exuding confidence. This makes for many frustrated pond owners. Maybe the Pond Boss owners/experts should start a nationwide certification process for pond builder that offers training with a test at the end (with a fee of course)? Then there would be a list to select from and perhaps a feedback system could be set up to be sure certified pond builders were walking the talk.
