Seen

Lakes: Almost all Austrian lakes are glacial lakes which were formed by glacial erosion of glaciers of the Ice Age and the damming of melting waters through moraines and other erosion deposits; Lake Constance was formed by the Rhine Glacier, the lakes of the Salzkammergut District (more than 40 lakes) by the Traun Glacier. Other lake districts can be found in Carinthia and in the Flachgau region belonging to the province of Salzburg. Many of the lakes existing today consist of what remained of much larger glacial lakes. Lake Neusiedl is a steppe lake, which was also formed in the Ice Age through the eroding and depositing activities of the forerunners of present-day rivers.
