Lake Czorsztyn is a man-made reservoir on the Dunajec river, southern Poland, between the Pieniny and the Gorce Mountains. It owes its existence to a dam, which is located in the village of Niedzica.
The dam itself was completed in 1995. Its measurements are: 56 metres high, 400 metres long and 7 metres wide on top. The lake has the area ranging from 4.15 square kilometres to 13.35 square kilometres. Usually, its area is approximately 11 square kilometres, with the length of 9 kilometres and width of 1.5 kilometres. Maximum depth is 50 metres, and average depth is 17.6 metres. Total length of the shoreline is 29.7 kilometres. Below the dam there is a much smaller Sromowce Lake, which regulates the water level of Czorsztyn Lake.
