I'll take a shot at answering.
Please be aware that ice on lakes can be tricky due to many variables....snow insulation, springs underneath the ice, currents, has the water authority dropped the lake level?, ambient temps, etc.
Be extremely cautious, we had a grandfather and his 5 yr old granddaughter go through the ice on a snowmobile day before yesterday
Both survived.
Moose tracks on the ice usually means ice can support a Super Cub landing or 6" of good freshwater ice.
C206...C185 min of 8" of freshwater ice to land with skis or wheels
If staying(parking) overnight I would want 10" for the Cub and 12-13" for the Cessna.
Also cross pressure cracks at right angle.
Have a Merry Christmas!
