The image shows a group of people standing on the shore of a lake. The lake is surrounded by houses and trees, and the sky is cloudy. On the left side of the image, there is a sign that reads "DANGER" with a red circle and a line through it. Next to the sign, there are two people, one wearing a blue shirt and the other wearing a black shirt and a white cap. The person in the black shirt is standing on a green mat and appears to be preparing to swim. There is a red and white striped barrier tape around the lake, and a metal barricade on the right side.
