It happens when the water below the ice goes down. In our case the water is going out of the lake down the Detroit river into Lake Erie. The water is currently being blocked at the 3 main Chanel's that feed the lake Saint Clair from the north that comes down the St. Clair river from Lake Huron.the ice is actually blocking the downstream water flow like a giant dam of ice.The whole sheet of ice in the canal which is 55 feet across actually drops all at once in our case today dropped once 7 inches the it dropped another 6 inches.It also forms pressure ridges that can get to be 8-15 feet thick and that happens when the wind blows the ice in one direction and the ice literally pile up on its self.
