The ice year at Duncan Lake, modelled
Modelled from air temperature, not an ice report. It says nothing about whether ice will hold you.
The model treats Duncan Lake as too large and deep to freeze over, so it gives no freeze-up or ice-off dates. On air temperature alone it would have frozen in 65 of 65 winters since 1960.
We have no ice fishing regulation on file for Duncan Lake either way. Check the current BC Freshwater Fishing Regulations Synopsis before you plan a trip.
Whether a lake is open to ice fishing says nothing about whether its ice will hold you. Ice conditions vary year to year and across a single lake. Check locally before going out, every time.
