Minnesota ice fishing: when each lake typically loses its ice

What “typical ice-out” means

For each lake, the middle date its ice went out over the winters on record from 1994–2023 (at least 5 winters). Half of those springs it went out earlier, half later. Earliest and latest show how far a spring can swing. It is a record of the past, so use it to plan the season, not to decide whether to walk out.

• Among the earliest in these recordsIowa Lake, Martin County; North Silver Lake, Martin CountyTypical ice-out Mar 23
• Among the latest in these recordsGreenwood Lake, Cook CountyTypical ice-out May 9

Each lake’s typical date covers the winters on record for that lake, which differ from lake to lake.
