Thanks for the links, GBfisher!
LunkerHunter -- yep, I'm talking about the same lake. My parents are in DeeBank, at the outflow end of the lake. I don't fish it too much during the winter, as the lure of trout is so strong I'd love to get out there with you though...never pulled anything except perch and rockbass through the ice on 3 Mile.
I would bet that right now, you could walk in the shallower protected areas on 3 Mile, but it could still be a bit dicey across the whole lake.
Just called up there for the latest report, and basically the lake is covered in snow...no tracks except for deer tracks.
I still think with all the cold weather there'll be enough to walk on in protected areas...but I hope to have a new year's report Will keep you posted!
