First off thanks for all the replies so far.

Ewest, what are these manuals you are speaking about?

I will stock with FHM and see if I can get a few shiners today!

7 Feet is all I have, unfortunately there's only another couple feet of clay, then rock. I have the culvert set at 7'6" after that it starts to flood my lawn.

The ice will probably freeze about 12-24 inches on a bad year. That leaves me with about 5'6" to 6'6". I am planning to aerate it with some bubble line and a good compressor and I am hoping this will be enough.
