Today, Lake Kaltern is heavily influenced by humans: especially on the west and east banks, there are bathing establishments, campsites, restaurants and commercially used areas that lead to a burden on the natural environment. This makes this quiet zone on the south bank all the more important. It is a nature conservation project in which two ponds and bays were built in the reeds. These are intended to provide new habitats and nesting places for water birds and spawning grounds for fish.
