AUBURN — The ice on Lake Auburn is officially out. 

When exactly that happened depends on who you ask.

“We don’t wait for it to be 100 percent off, just 90 percent or more to call it,” said Mary Jane Dillingham of the Auburn Water District. 

According to the Auburn Water District’s records, the official ice-out date this year is Friday, April 12.

According to the State of Maine Division of Parks and Public Lands, this year’s official ice-out date is April 14.

“I don’t know who did it for the state, or if they just went on Sunday and saw it was gone,” Dillingham said, “but it will be April 12 in our records.”

April 12 is a unique date. Since 1900, no other ice-outs have been called on April 12.

This year’s date is early, relative to the many years of records, but by no means the earliest ice-out on record. Last year, March 23 became the second-earliest ice-out on record. The record was set only two years prior, on March 22, 2010.

The latest ice-out is the first on record, May 8, 1836. The latest ice-out on Lake Auburn since 1900 happened three times on May 6, in 1939, 1940, and 1972.
