Lake Grundlsee is situated at the southern foot of the Totes Gebirge in Austria, in the Styrian part of the Salzkammergut. It lies at an altitude of 708 m above sea level. The municipal seat of Grundlsee is located on the northwest shore. The outflow of the Grundlsee is the Grundlsee Traun, which drains into the Danube via the Traun. With an area of 4.22 km2, Grundlsee is the largest lake in Styria. Its location, situated in a beautiful setting, has made it an important tourist destination and a popular bathing lake, as well as a diving and sailing area. The Daffodil Festival, Austria's largest flower festival, occurs every third year at Grundlsee. A professional fisherman manages the lake. The most prevalent fish species is the lake char (Salvelinus umbla), which is marketed as the Lake Aussee lake char.
