At least six people are thought to have died in boating accidents over the weekend.
Divers in Lake Michigan resumed looking for one victim Monday morning, a man who's been missing since the power boat he was in capsized during a charity poker run on Saturday morning.
Authorities say the missing man, 42-year-old Mike Scaffidi of Hartland, Wisconsin, is presumed dead.
Another passenger, 20-year-old John Desousa Junior of Bristol, Rhode Island, died following the Saturday morning crash near Holland.
Investigators said the power boat was carrying four people as part of the annual "Smoke on the Water Poker Run" event for the Make-A-Wish Foundation when it capsized as its driver made a turn in about 75 to 80 feet of water.
