ICE IN | ICE OUT

What is the "Ice In | Ice Out Contest"?

Every year, the members of the LRIA submit their guesses for the exact day and time that Lake Riley will freeze solid (Ice In) and then when it will thaw in the spring (Ice Out).

Some people rely on publications like the Farmers Almanac.  Others use seismic and atmospheric measurements to predict exactly when the lake will freeze or thaw.  Some residents proclaim that they can just "feel it in their bones".  However, talking with some former winners, their strategy has been less scientific and more of a "random guess".  Regardless of how you arrive at your decision, you can join in the fun by submitting an entry.


Rules of the Game:
  • All submissions must be received by November 15th
  • Open to current LRIA members.  Not a member?  sign up here
  • Only 1 entry per LRIA member (couples can submit a separate guess for each person)
  • All valid entries will be posted here on the website after the 15th. 
  • Winners will be contacted via email. 
  • Official time and date of Ice In and Ice Out is determined by the members of the Social Committee.

The third-earliest open water came fast this year with the warmth this spring.
​Earliest Ice-out dates:

2000  -  March 8
2001  -  March 14
2016  -  March 16
Our latest Ice-out was on April 28th, 2013, a whopping 44 days later than this year!

Although Lake Riley is not included, the Minnesota DNR has a nice chart that shows the 2016 Lake Ice Out Dates.
