Definition of Lake Ice In
The definition of lake ice in can vary from lake to lake. For the citizen observers reporting data, ice in occurs when the entire lake is frozen over for the first time and the ice cover remains through winter. Observers do not report ice thickness.
Definition of Lake Ice Out
The definition of lake ice out can vary from lake to lake. For the citizen observers reporting data, ice out occurs when the lake is completely free of ice. Or, it may be when it is possible to navigate from point A to point B. Ice out may also be when a lake is 90 percent free of ice. Observers use consistent criteria from year to year when reporting lake ice out dates.

Many thanks to Ron Stokesbary, Russ Link, Bill Elliott, Mary Jane Black and George Hess for historically tracking this data.
This plaque was created for George Hess (Lake Wabedo). He diligently tracked the freeze - thaw cycles while living on Lake Wabedo.
