Lake Żywiec

Lake Żywiec is a large artificial lake located in Żywiec County, Silesian Voivodeship, Poland, near the city of Żywiec, surrounded by the Beskid Mountains and the Tatra Mountains. The lake is an important part of the Vistula River basin and is connected to the Soła River, which flows through the Silesian Beskids. The construction of the lake was influenced by the Polish Academy of Sciences and the University of Silesia in Katowice, with the goal of creating a stable water supply for the surrounding region, including the cities of Bielsko-Biała and Cieszyn. The lake's creation also affected the nearby Oświęcim County and the Kraków Voivodeship.

Introduction

The lake has a surface area of approximately 10 square kilometers and a maximum depth of 26 meters, making it a popular destination for water sports and fishing, with species such as European perch and Northern pike being common. The lake is also home to several islands, including the largest island, Wielka Żywiecka Island, which is a popular spot for hiking and birdwatching, with species such as the White-tailed eagle and the Osprey.

The lake's shoreline is approximately 20 kilometers long and features several bays and inlets, including the Żywiec Bay and the Sporysz Bay. The lake's water level is regulated by the Żywiec Dam, which is operated by the Polish Ministry of Environment and the National Water Management Authority, with the assistance of the European Environment Agency and the World Wildlife Fund.

History

The construction of Lake Żywiec began in the 1960s, during the Polish People's Republic era, with the goal of creating a stable water supply for the surrounding region, including the cities of Katowice and Kraków. The lake was created by building the Żywiec Dam on the Soła River, which was designed by the Polish Academy of Sciences and the University of Silesia in Katowice, with the assistance of the Soviet Union and the Czechoslovak Socialist Republic. The dam was built using concrete and steel, with a height of 39 meters and a length of 260 meters, and was officially opened in 1966 by the Polish Prime Minister, Józef Cyrankiewicz. The lake's creation had a significant impact on the surrounding region, including the displacement of several villages and the creation of new settlements, such as Żywiec and Lędziny. The lake has also been affected by several floods, including the 1997 Central European flood and the 2010 Polish flood, which were caused by heavy rainfall and snowmelt in the Carpathian Mountains.

The lake's surroundings are also home to several nature reserves, including the Żywiec Landscape Park and the Silesian Beskids Landscape Park, which are protected by the Polish Ministry of Environment and the International Union for Conservation of Nature.
