Zeller See, Austria
Zeller See is a lake nestled in the Austrian Alps, near the Hohe Tauern National Park—one of the largest protected areas in Central Europe. At 3.8 km in length, 1.5 km in width, and with a depth of up to 68 metres, the lake supports a range of water sports and tourism. Due to the presence of around 100 underground springs, the Zeller See remains largely unfrozen in the winter.
This Copernicus Sentinel-2 image, acquired on 12 April 2025, shows the deep-blue lake bordered by the towns of Zell am See and Schüttdorf.
Satellite data from Copernicus plays a vital role in monitoring global water bodies and mountainous regions, supporting communities in developing sustainable strategies which balance environmental preservation with recreational use.
