Welcome to PB. It's always good to have another Miserian on the board.

I've got a kinda sorta similar pond to what you're thinking of a few miles east of Columbia.

Think about SMB, HSB, RES, and YP. That's what I've got, with the addition of some accidental BG. I spend a LOT of time getting rid of BG.
The bass have only been in for a year now, so I can't really say if they're going to be able to control the BG long-term, but I'm thinking probably not.

Check out this thread to see what RES can do if you give them a little help:
