On the NRCS website, find the office that is in your county. Call them or go in to visit. They can tell you if your pond area will have enough watershed to keep it full, whether the soil is good, marginal or bad for retaining water, and other things. You are paying for them now through your tax dollars. They should also be able to tell you what size primary and secondary overflow you'll need, and give you a list of "pond builders" in your area. The key with that list is to ask them "If you were to call people on the list for quotes, who would the first 3 or 5 be that you'd call?"
