csullivan,
With such a big pond, you should seriously consider the advantages of having a it electroshocked. Fishing it will give you a general sense of the ponds contents, but it won't be the whole picture. The professional doing the shocking will be informative with all sorts of other tips and strategies. You'll probably end up saving time and money going this route. You're investing a substantial amount of money buying the property to begin with, so if you really want a top-notch fishing pond on this property, you'd be well advised to spend a little extra on researching it professionally.

Good luck and enjoy the fishing for years to come!
