An artificial reservoir in Krakow in Zakrzówek. It was created in 1992 after flooding an old limestone quarry. It consists of two reservoirs connected by an isthmus. The shores of the reservoir are one of the favorite places for recreation for Krakow residents, but swimming in the reservoir is prohibited due to the risk of drowning.
In 2023, a new swimming area was built in Zakrzówek, equipped with floating piers and swimming pools of various depths.
