A few comments:

I don't think Wood's diffuser is keeping a hole in the ice 'cause it's just too damn cold. I mean 31F below zero. Sh*t! Any air/gas would find some path of lesser resistance.

Cecil, I'm not suprised that your brook trout don't come into the shallows.....They wouldn't fit! Do you provide a couch, TV, and some beers for them? Some of the biggest guts/bellies I've ever seen.
