Lake Rożnowskie, located in the Lesser Poland Voivodeship, is a reservoir created by damming the waters of the Dunajec River. Its construction began as a result of a catastrophic flood in 1934, and the dam was completed in 1941, enabling the operation of the Rożnów Power Plant. The lake stretches 22 km in length and covers an area of 1,600 hectares. It features an irregular shape with depths reaching 30–35 meters, and its shoreline is highly developed, with numerous peninsulas and bays, making it an attractive tourist destination. Within the lake area lies the "Małpia Wyspa" landscape protection zone, where rare bird species, including the black stork, can be observed. The surrounding area is home to numerous tourist towns such as Tęgoborze, Znamirowice, and Gródek nad Dunajcem, offering a variety of attractions, including water equipment rentals and swimming beaches. Thanks to new investments, such as a wastewater treatment plant, the water quality in the lake has improved, enhancing its recreational appeal. The lake plays a key role in the region's water management, including water resource utilization and flood protection. Due to its rich ecosystem and scenic landscape, it is a popular destination for nature enthusiasts, water sports lovers, and tourists.
