Ice Out history
The “official” ice out dates are in the third generation for tracking. It started with Hazel Gayner in 1954, her son Dean Gayner taking over in 1999, and Dean’s daughter Jenna O’Brian taking over in 2010. The rule for ice out is that everyone must be able to get their dock in. Jenna has a number of volunteers around the lake who help keep her honest and report if too much ice is still present. In the end, it is her call.
