Minnesota's Lake Ice-Out Status as of May 10, 2004


The definition of lake ice-out varies from lake to lake, and individual to individual. For some, ice-out occurs only when the lake is completely free of ice. For others, ice-out is defined as the moment when navigation is possible from point A to point B. And yet for others, ice-out is when 90 percent of the lake is ice free. Due to the variable definitions of this rather subjective observation, the State Climatology Office attempts to contact the same individuals each year to maintain a consistent record. The table below will depict 2004 information obtained from this informal poll. The table is updated on Mondays.

Historical averages and extremes have been calculated for lakes in highlighted in green.
