Ice Out Declared April 17, 2017

Ice out on Lake Winnipesaukee, the largest lake in New Hampshire, was announced on Monday, April 17, 2017 at 8:31 a.m.

Ice Out is declared after all of the ice has broken up and the M/S Mt. Washington can navigate the waters and make all five of its ports of call: Weirs, Meredith, Center Harbor, Wolfeboro and Alton, free of ice.

Since 1887, ice out has been decided by a variety of means. Dave Emerson, of Emerson Aviation, has made the call since 2010. He flies two to three times a day over Lake Winnipesaukee to check on the ice.

Emerson Aviation posted pictures showing what was left of the ice at 11:20 a.m.  Emerson just declared ice-in at Lake Winnipesaukee on Feb. 15.

Ice-out typically occurs the third week of April.  Last year’s ice-out was the earliest date in recorded history on March 19, 2016.  The latest ever ice-out was in 1888, on May 12th.
