Ten Mile lake outside of Fergus falls on the 1st of January while walking out the their fish house. Both survived the frigid 12 foot depths. Please be careful, what was 9 inches of ice changed in two days!

Wow. Glad they are ok. Sounds like they were doing the right things. I wonder what changed the ice that fast? Only thing I can think of id massive school of Carp or a spring / creek nearby.
