I have seen a number of articles posted lately regarding ice fishing safety and ice thickness. In most years, mid January ice conditions are never in doubt, usually we have 20″ or more in most areas and 24″ plus in the northern half of the province.
An thick blanket of snow early in November has insulated the ice and mild weather has prevented the ice from thickening. Mild weather can also promote run off and weaken ice around shorelines and spring inlets.
The handy chart below come from the Saskatchewan government and is an excellent visual.
