The ice year at Seton Lake, modelled

Modelled from air temperature, not an ice report. It says nothing about whether ice will hold you.

The model treats Seton 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.

No ice fishing closure is recorded for Seton Lake, so the general regional regulations apply.

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.

Seton Lake climate, 1960 to 2025
