Łebsko, also known as Łebskò, is the third largest lake in Poland by surface area, located in the Pomeranian Voivodeship on the Słowińskie Coast. It covers an area of 71.4 km², with a maximum depth of 6.3 meters. The lake is eutrophic and characterized by brackish water, primarily due to the influence of the Łeba River and periodic inflows from the Baltic Sea. Łebsko is part of the Słowiński National Park, established in 1967, which ensures its special environmental protection, and the area surrounding the lake falls within several strict nature reserves. The history of the lake dates back to the 13th century, with the name "Lebzco" documented in historical sources, linked to the Łeba River. The lake's flora includes numerous plant species, such as white water lilies and yellow water lilies, as well as reed beds that serve as habitats for many bird species. Eutrophication poses a threat to water quality, making ecological protection a key aspect of its management. Tourism on the lake includes passenger shipping to destinations like the Museum of Rocket Launchers and the Museum of the Słowińska Village, combining cultural and educational experiences. Łebsko is also popular among kayakers and anglers, attracting enthusiasts of active recreation. An interesting fact is the observable changes in the lake’s shoreline, which has shifted significantly over the past centuries due to sand deposition and the expansion of reed beds. As part of a unique ecosystem, Lake Łebsko represents an important area of biodiversity and cultural heritage in Poland.
