There is so much to learn about managing a pond, especially if there are very specific goals. I could see you managing what you have now, with a sidethought of a complete re-do as a "possibility". Use the pond to learn, get to know it, make some mistakes. It may turn out better than you think. If not, re-do it and you will have a better chance for success at that point with the knowledge gained. Just decide how much money you are willing to sink into it as is, versus a re-do. Some of the things you might even be able to re-use into the new pond if that day comes. I have seen a lot of newbies strike out for that "perfect" pond, only to be thrown a curve ball because of bad choice in a weak moment.
By your description of your goals and what you got, you may not be far off from getting it. Probably should aerate for better water. Might need to thin some bass... learn about which and how much. Read lots on the forum, and then read some more.
