The dam is very well constructed but there are wet areas below it where it attaches. The builder claims that these were springs that he could not get behind the dam.
a)...sake of argument; is the flow of water behind the dam seemingly enough to the amount you might expect to keep your pond low if it were leaking?
b) Was a core cut (keyway) before construction of the dam? If yes, specifics of dimensions and construction. If no, specifics of grade preparation for dam construction.
c) How does your contractor explain the situation (not trying to be a wiseguy...seriously. Let's continue with the idea that he is pond-knowledgeable and honest. He should have good input.)

-edit; d) What is your County NRCS's take on it?
