Augured a hole off our dock and there is 2″ of ice, ice off the dock is a bit thicker than the lakes main ice sheet. The last 3 nights of -10 got it done. Next few days are a bit warmer but no melting will happen, mid next week the outlook is calling for highs of -6 to -8 with nighttime lows of -13 so the outlook looks favorable for the hardwater season to begin soon..
