Rent to own, maybe?

The more I look into a YP/SMB combo, the more I like. I have a ton(s) of big granite boulders on my place and also 24 cubic yards of river rock for structure. (dry creekbed project gone bad)

So let me highjack my own thread and let's build a SMB/YP pond. The size will be a little over a 1/4 acre. Plan on using aeration. Crawdads. Max depth 8', with an average of 4'. Is this deep enough? I was planning on aerating the deepest part of the pond, but would I want to leave a deep/cool area?

What say you pondmeisters?
