In the winter of 2017-2018, the ice thickness at the lake got up to 13 inches. For those of you who have had a dock crushed by ice in the past, here are some interesting numbers.
(161 acres of lake x 43,560 sq. ft./acre x 13 x 57.2 lbs./cu. ft.)/(12 x 2,000 lbs./ton) = 217,291 tons of ice.
By comparison, a 747 airliner weighs 202 tons. So that would mean that an equivalent of 1,074 747’s would be available to crush docks if left in all winter!!
