Bob,
Bill Cody would be an asset if he has not contacted you yet. He handles technical material very well and really know his stuff on aerating northern ponds with diffusers.
I would be willing to do an article on trout ponds once I get all my research done and the bugs worked out. That won't be for another year.
Case in point about covering northern ponds. Did you see where Scott Trava says he has 152 ponds to take care of? Lots of ponds north of the Mason Dixon line!
