I think the photos are real. The ice covering is caused by spray from the lake water freezing onto the vehicles, not precipitation. The ice is not covering the buildings because they are far enough away from the lake.
As 'Smith' says, clearly a result of spray from the lake. In this pic, the weight of the ice formed has been a little more damaging. I suspect the brickwork visible bottom left of the shot is part of the marina/harbour wall, so again, the spray would have come over this wall, and formed on the boats closest to it.
