View of the Feldsee in autumn

The Feldsee (also Feldbergsee ) is a lake in the south of Baden-Württemberg at the foot of the Feldberg east of Freiburg im Breisgau , it is part of the Southern Black Forest Nature Park . It is the highest lake in Germany outside the Alps.

Geology and geological history

The approximately 97,500 m² large and up to 32 m deep Karsee was created by glaciers from the last ice ages . The largest cirque lake in the Black Forest is bordered on three sides by steep walls up to 300 m high. It is almost circular, with a diameter between 350 and 370 meters. The elevation , which is open to the northeast at 1,100 m and which allowed larger amounts of snow to accumulate and maintain, was the cause of the armchair-like shape of the terrain with the steep back wall, the flat floor and the moraine wall in front. After the ice melted, the lake formed above the heaped rubble walls. The Seebach flows through the Feldsee, which rises between Feldberg and Seebuck in the Grüble , falls down the Karwand in the Feldsee waterfall and later, on the other side of the Titisees , bears the name Gutach . For several hundred thousand years this was the upper reaches of the original Danube , which the present Danube flowed into near Immendingen , and for several tens of thousands of years the brook has been the upper reaches of the Wutach , which drains to the Rhine .

Below the Feldsee, a further, smaller lake was enclosed between moraine walls , which silted up through peat formation into today's botanically valuable field lake bog .

natural reserve

There is now a general swimming ban in the Feldsee. This serves to protect a rare species of prickly bream ( Isoetes echinospora ), an underwater fern that thrives in a depth of 1–2 m and in Germany only occurs in the Titisee except in the Feldsee. This plant relies on nutrient-poor lakes with cool, very clear water. There is a so-called Bannwald around the Feldsee . This mixed forest is also under nature protection and is left to its own devices. The nature reserve has existed since 1937 and is the oldest nature reserve in Baden-Württemberg. The Feldseefelsen are prohibited from climbing. The Feldberg guards (rangers) pay strict attention to compliance with these rules. Here you can find rare plants such as the alpine milk lettuce , the Turkish lily , the wolf's monkshood and sundew .

Access

There is no direct road to the Feldsee. It can only be reached via hiking and cycling trails. The closest parking spaces are 3–4 km away in Feldberg-Bärental ( Kunzenmoos hiking car park ) and on the Feldberg. The Feldsee can be easily reached by bike from Alpersbach via the Rinken . The lake can be walked around on a well-developed walking path. The Gasthaus Raimartihof is located 490 meters east of the Feldsee .
