Great blue water in the Auensee and great for swimming

The Lech barrages along the Lech are important habitats for water birds and offer ideal conditions for breeding, resting, and foraging. Particularly noteworthy are: • Lechstaustufe 23 (Mandichosee): This reservoir is an important resting and breeding ground for various water bird species. Regular excursions allow for the observation of breeding and migratory birds both on the reservoir and in the adjacent floodplain forest. • Lechstaustufe 27 (Feldheimer Stausee): Designated as a nature reserve since 1982, this reservoir serves as an important breeding and moulting area for water birds, as well as a resting and wintering site for Nordic species. • Lechstaustufe 20: Near this barrage, there is a water bird paradise where hundreds of water birds gather between a bird island and the eastern bank. These areas are not only of interest to ornithologists but also offer nature lovers the opportunity to experience the diversity of water birds in their natural environment. It is important to be considerate of the wildlife during visits and to observe the protective regulations in order to preserve these valuable habitats.

The Auensee near Unterbergen has its intense blue color due to several natural factors: 1. Minerals and sediments: The water of the Auensee contains fine mineral particles and rock sediments that come from the Lech and the surrounding limestone Alps. These particles reflect and scatter the light in a way that makes the water appear in intense blue and turquoise tones. 2. Deep bottom and clear water: The Auensee is comparatively deep and has very good water quality because there is little suspended matter that could absorb the light. This makes the water appear even clearer and bluer. 3. Algae growth: Certain types of algae that proliferate in the Auensee can influence the color of the water. In this case, mainly types of algae grow that allow the blue light to pass through and thus enhance the natural color. 4. Reflection of the sky: On sunny days, the blue color of the sky is reflected on the water surface, which makes the color of the lake appear even more intense. These factors together make the Auensee one of the most visually striking bodies of water in the region and give it its characteristic, bright blue color.

The Auensee near Unterbergen is not only a popular local recreation area, but also a place with a special scenic charm and ecological significance. The lake was created as part of the Lech regulation and the construction of the Lech dams and is part of the so-called Lechauen ecosystem. It is embedded in the Lechau forest, a valuable natural area with a diverse range of flora and fauna. Nature and ecology The Auensee is surrounded by dense riparian forests that provide a habitat for a variety of animal species. Rare water birds, amphibians and fish can be found here, which find ideal conditions in the calm, clear water. The shore areas are largely natural, which promotes biodiversity and gives the lake a special, nature-loving atmosphere. The lake is also in the catchment area of the Augsburg - Western Forests Nature Park, which means it fits well into the region's nature-oriented landscape. Leisure and relaxation The Auensee is also known for its quiet, relaxed atmosphere and attracts many people looking for a place to relax. The lake shore offers not only bathing areas and sunbathing lawns, but also shady spots under trees, which are particularly popular on hot summer days. The clear water quality is regularly checked and makes the Auensee an attractive bathing resort. Hiking and cycling There are signposted hiking and cycling trails around the lake that connect the Auensee with other attractions in the area, such as the Mandichosee or the Lech barrages. These trails lead through the Lech valley and offer varied routes through forests, along the Lech and past other bodies of water. They are suitable for both relaxed walks and sporty excursions. Historical context The Auensee is located near the Lech barrages 22 and is part of the historic Lech regulation measures that were carried out in the 20th century. These measures were intended to contain flooding in the Lech Valley and at the same time generate energy through hydropower. The Auensee near Unterbergen combines relaxation, nature experiences and scenic beauty and is a popular destination for families, hikers, cyclists and nature lovers alike.

Bathing lake, but not specially created: very clean water

Very crowded on hot days in midsummer, best to stop by on cooler (swimming) days or in the evening after a tour!
