Once the wind can get at the open water that has been created with shore melt it does not take that long for the wind action to clear the entire lake of Ice. Most years the Ice is cleared starting at the East end with a stiff East wind creating the waves that break up the Ice down to the West end. Which is why most years Ice is driven up on shore large distances on the NW side of the lake. The odd year the Ice will go out with a West wind which demolishes many wharves on the south side. Does not matter how sturdy they are built the Ice has the power of many D8's
