Recap of 2012 Ice Out

2012 will go down as more of the more memorable early ice out seasons in Minnesota history. Many lakes in the state set new ice out records, including lakes that have ice out data for 75 years or more. The lakes that lost their ice first in Minnesota were Iowa and Hall in Martin County on March 12. The last lakes to lose their ice were Lake of the Woods, Rainy Lake, and Greenwood Lake during the second week of April.

The ice out season surged northward quickly with the record setting warm March 2012, whose temperatures eclipsed past historical warm Marches like 1878 and 1910. In the Twin Cities the average temperature finished at 48.3 degrees, handily breaking the old record of 45.0 degrees set in 1910. The only thing that prevented virtually all the lakes to lose their ice in March across the state was a cool down over northern Minnesota for the last week of March, including a modest snowstorm.

Here are some of the larger lakes that have set new records in 2012.
