So much broken ice has flowed from Lake Erie in recent days that Niagara Falls has become partially blocked. <br /><br />High winds on Sunday smashed sections of the frozen surface of the lake and now huge slabs of ice are flowing down the Niagara River.<br /><br />Much of that ice is collecting at the famous falls, reducing the volume of water.<br /><br />A video filmed on Monday showed the Bridal Veil Falls - the smallest of the three waterfalls which make up Niagara Falls - had almost completely stopped flowing.
