Thanks for the suggestions guys!

Here is a little more info on the specific lake: http://www.iowadnr.com/fish/fishing/lakes/roc50.html

Now the main thing I am trying to figure out is what depths to put the structure, relative to where the crappies and bluegills will be wintering. I am not familiar with the depth habits of panfish in the winter season.

That contour may be a little hard to read, but you can zoom in on it. Max depth about 20ft, most of lake basin about 14 FOW.

I'll be sure to post pics putting the structure down and once the hard water hits, hopefully some videos with the aquaview!
