Ice-out on Beaver Dam Lake happened March 8, according to Dick McMillan.
McMillan, who has been maintaining the record most recently, has data going back to 1916 with recorded ice-out dates. His records indicate the earliest date ice has gone off the lake was Feb. 28 in 1998. The latest ice-out date was April 20 in both 1973 and 1972.
McMillan said ice-out is determined when a boat can travel from the dam in Beaver Dam to the long bridge on the north end of the lake.
