2017 recorded Ice-out as 4/10/17 @ Noon, ten days earlier than average.

My 2017 Winter Ice-in calculations are figured as follows:

As of 2016, the average amount of elapsed days to ice-in after New Years Day is 345.388 days, which equates to an ice-in date of 12/12/17.

As of 2016, the average amount of water days after the previous ice-out date is 235.078 days, which based on the ice-out date for 2017 (4/10/17) equates to an ice-in date of 12/1/17.

An absolute average of these dates would be 12/17/17. There is nothing scientific about this, it is merely numbers. When God decides on ice-out, it will happen.

Average Days of ice , as of 2016 129.818

Average Ice-out Date is: April 20

Average Days of water, as of 2016 235.078

Average Ice-in Date is: December 12

In 2017, all Cardinals were awarded the highly sought after Lake Lucerne loon pin of Excellence.
