GRAND HAVEN, Mich. An 18-year-old man and a 17-year-old girl were rescued Saturday morning after being swept into Lake Michigan. The two Lake Orion teens were on a pier in Grand Haven when a wave struck them and dragged the two into the lake. Officials said they treaded water until someone was able to get a life-ring to them and pull them out of the water. The man was treated for a minor injury and is expected to be OK.WOODTV reports the pier has been shut down until lake conditions have improved.
