Bear Lake State Biologist, Scott Tolentino, reports that data
has been collected on the freeze over and thaw dates since 1923. Including
2013, that is 91 years of data.
- On average, Bear Lake has frozen over 70% of the time but only 56% of the time in the last 25 years.
- Longest period of no freeze: 3 years ('98, '99, '00)
- Earliest freeze over: 12/27/1985
- Latest freeze over: 3/12/1965
- Average date of freeze over: January 18 (It froze on January 18, 2013)
- Average date ice gone: April 10 (It officially opened up on April 9, 2013)
- Average number of days frozen = 74 (In 2013, we had 81 days of ice cover (about 7 more than the long term average), and yes, our day of freeze and day of thaw were pretty much average so some might assume we should have only had 73 days according to my numbers, but calculating it this way would be taking an "average of an average”), so 81 days of frozen lake is correct for 2013.)
- Earliest date ice gone: 2/8/1941
- Latest date ice gone: 5/14/1984
- Shortest amount of time frozen: 3 days (1941)
