When Does Maud Lake Freeze? Typical Ice-In Nov 24, Ice-Out Apr 23
Maud Lake in Becker County, Minnesota usually freezes over around Nov 24, and usually has ice-out around Apr 23, based on Minnesota DNR ice observations recorded between 2005-2013. That works out to roughly 215 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 Maud 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 Maud Lake has landed as early as Apr 11, 2005 and as late as May 11, 2013 — a spread of weeks around the Apr 23 median. Freeze-up has ranged from Nov 21, 2008 to Nov 27, 2007. 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. Maud Lake carries an overall water-quality grade of A — the full breakdown is on the lake report.
