Paul Porter designed the high tech apparatus shown in the picture that will determine the time of ice-out with split second accuracy.
He and Al Cowperthwaite built the device which sets a new standard for ice-out detection equipment.
Resources for better prediction:
To help in this year’s prediction, refer to this record of ice-out dates since 1949 supplied by Al Putnam. The Maine Dept. of Agriculture, Conservation and Forestry has compiled information on state-wide ice out dates and similar information is on this page, provided by Lake Stewards of Maine. The US Geological Survey has issued this paper on the New England ice-out date trend.
