DH, I think your best recourse would be to bite the bullet and get the pond guy to repair the breach before your whole dam is gone. I think you are probably right in your analysis but you can never prove it in court. You should ALWAYS have a written contract when dealing with a contractor of any type. Even if you did, the pallets would cast enough doubt on it to prove it in court. Remove everything from your pond that can float and if it happens again, your case is much better. Good luck!!
