When Does Two Rivers Lake Freeze? Typical Ice-In Nov 30, Ice-Out Apr 7
Two Rivers Lake in Stearns County, Minnesota usually freezes over around Nov 30, and usually has ice-out around Apr 7, based on Minnesota DNR ice observations recorded between 2002-2016. That works out to roughly 237 days of open water a year. These are typical dates across many winters, not a forecast — individual years swing by weeks in either direction.

These are dates, not an ice-safety reading
A typical freeze-up date tells you when Two Rivers Lake has usually iced over — it does not tell you the ice is safe, and we hold no thickness measurement for this or any lake. The Minnesota DNR is explicit that no ice is ever completely safe: thickness varies across a single lake, and current, springs, aerators, and insulating snow all weaken it. Ice that held a truck last week may not hold a person today.
Read the ice-thickness guidelines before going out, and check current conditions with the Minnesota DNR ice-safety page and local bait shops, which track conditions lake by lake.
How much the timing varies
Ice-out on Two Rivers Lake has landed as early as Mar 16, 2016 and as late as Apr 24, 2008 — a spread of weeks around the Apr 7 median. Freeze-up has ranged from Nov 28, 2007 to Dec 12, 2002. That year-to-year swing is why a median date is a planning tool, not a schedule. Freeze-up is driven by accumulated cold after the lake turns over in fall; ice-out by late-winter air temperature, sun angle, and how much snow sits on top of the ice reflecting it. Two Rivers Lake carries an overall water-quality grade of B — the full breakdown is on the lake report.
