Welcome and that is a very beautiful pond. Your question is very wide open. I would bet just about anything could be done with that BOW with enough time and money. It would help if you narrowed down your goals.
FWIW- If I were looking at a BOW like that, my first move would be to get a Pond Manager with no less than 15 years of experience on site to take a look. He or she would be able to tell you what is possible and at what cost.
Be verrrry carful. This pond stuff is addicting and pry's open even the tightest of wallets (just ask my wife).
