The Venedigerkees in the Hohe Tauern National Park is the easternmost tributary glacier to the former tongue of Obersulzbachkees. As a result of the strong retreat of Obersulzbachkees, the glacier disintegrated into several tributary glaciers, with a large lake remaining at the location of a famous serac zone, the 'Türkische Zeltstadt'. Hydrological monitoring of the area is done by the Hydrological Survey of the Federal Government of Salzburg (DI Hans Wiesenegger) who initiated the mass balance monitoring programme together with Heinz Slupetzky and the Institute of Interdisciplinary Mountain Research of the Austrian Academy of Sciences. The mass balance of the Venedigerkees is measured since 2011/12 with the direct or glaciological method.
