We had a cottage on Round Lake in the Tri lakes area, IN. Almost every winter there were two large areas that usually didn't freeze because of springs. Until I saw this I had no idea springs could do this. A few years ago I found a stray dog that had broken through the ice and drown in my pond so I watch my dog very carefully when the ice is thin as it is now in this warming weather.
This is Round Lake. Beautiful but could be dangerous.
