This is a photograph of the Upper Lake dam in Karpacz, Poland. The dam is a substantial stone structure, with a walkway along its top guarded by a metal railing. Several people are visible on the walkway, some walking and others sitting. Water is cascading down the face of the dam from an opening, creating a foamy spray as it enters the body of water at the base of the dam. The stone wall of the dam is partially covered in moss and vegetation, particularly on the section where the water is flowing. The sky above is a mix of blue and white clouds.
