I can offer up some cullable lm bass if you are interested.

My pond had walkable ice starting late december and is still covered in at least 8" of ice on 90% of the surface area - snow cover was roughly 10 weeks. 0 outlet flow period was 10 days - thats a pretty hard winter for ice thickness and snow cover. I bet you can make that pond bounce back rather quickly!
