Sorry to read of your winterkill. Down here at 6500 elevation, we lost all of our trout, too, last winter. That's with the aerator running and a good hole open in the ice. It seems the rest of the fish survived-LMB, YP, BG, GSF, GC. Although, come to think of it, I haven't caught a single SMB this summer. We had few smallies however.
I guess you are coming back to Colorado for elk?
