Looks like ice-out is underway. I got the following email from Canoe Laker Charlie Plant yesterday:
"Well here I sit, hoping to be on the lake for a fourth year in a row when the ice goes out but I don't think I'll make it. There are open patches of water on Tea Lake and Smoke is dark black, ready to go out any day but Canoe may be a day behind those two. The water level is very high ... and there are massive cracks in the ice and water at the shore. The ice has disintegrated and all it needs is a lot of wind, rain or sun to disappear. As we won't have enough of any of those for a while, it will be a few days yet but this week for sure."
And the official Algonquin Park Ice Out Conditions page said today that they expect ice out in the next 5-10 days. Head on over to the site for details, including some great arial photos.
