Bleibtreusee

Tagebaurestsee

The Bleibtreusee is one of the remaining lakes by lignite mining in the southern Rhenish lignite mining area in North Rhine -Westphalia southwest of Cologne near the cities Brühl, Hürth and Erftstadt in the Rhine -Erft. He is a member of the Rheinland Nature Park.

Location

In the middle part of the Ville, where from 19 to mid-20th century in smaller pit fields, the brown coal was mined, today's Ville Lakes area, a 50 km ², vast area with mixed forests and over 40 lakes originated.

The Bleibtreusee located west of the undertaking in the immediate vicinity Brühler hamlet of Heath and north of Erftstadt district Köttingen. Its spacious parking lots are accessible via the B 265 ( Luxemburger Straße ) or from the Brühl center of the L 184 ( Theodor -Heuss -Straße).

Name

The lake is by Hermann Bleibtreu (1821-1881), one of the pioneers of the lignite industry in Brühler room, named in 1874 for the first time a mine field south of Heath unlocked (later Gruhl work ).

Description

As part of the reclamation measures of the Rhine and the brown landscape authority of the Rhine Erft circle was again a rich variety of flora and fauna located. The Bleibtreusee as one of the medium-sized lakes in the chain of lakes in the Ville is a nutrient-poor, calcareous Still waters at Brühl Heath, not far from the mountain lake Heider. It is in the waters around artificial, created by former lignite open cast mines remaining lakes with shallow water, surrounded by forestry used larger forest areas with site-specific mixed woody plants. An example is the change of poplar, pine, red oak, larch, alder, beech, locust and birch.

The lake has an area of ​​about 74 ha small oblong island at the southern edge of the breeding birds remains Reusees is reserved and has naturally untamed vegetation. The depth to the north of the island is up to 16 m, but is of little interest for scuba divers because of the dark substrate. As Heider mountain lake raptors find ( Pandionidae ), grebes (Podiceps cristatus ), Wild Geese ( Anseriformes ), kingfisher (Alcedo atthis) and Common Moorhen ( Gallinula chloropus) that are protected on said island as breeding birds.

Under the surface has settled and the Verschiedenblättrige milfoil ( Myriophyllum heterophyllum ) over the decades. This species prefers inhabited static and slow moving waters and partly forms dense stands out. By Spangehl & pawing Berg ( 1985) the occurrence in North Rhine- Westphalia was first described from the Heider mountain lake at Brühl, where the species is still to be found. In addition, the island as a result of eutrophication in Bleibtreusee west densely formed wide Unterwasserfarnflächen below the surface, which would severely impede water sports with sailing dinghy or windsurfing boards and are therefore hedged.

At the margins of water bodies can be found, among other things: Little hedgehog piston ( Sparganium minimum) - Common water bladderwort (Utricularia vulgaris) - Broad-leaved helleborine ( Epipactis helleborine ).

Furthermore, it should be maintained or expanded by the development and promotion of reed zones of the water habitat for many migratory waterbirds in the fall and winter and other aquatic animals such as amphibians ( toad, Bufo viridis) and aquatic insects (eg, scarlet dragonfly, Ceriagrion tenellum ).

Use

Parts of the terrain remain left to their own and are declared as nature reserves. Ville, Kotte forest and reclaimed former brown coal mining areas with lakes also serve the people in the Cologne / Bonn region as a recreational area. On shared portions of the remains Reusees windsurfers and small sailing dinghies are approved and at the northern end consists in July 2007 a ​​well- frequented from the beginning waterskiing with attached restoration adjacent to the flat sandy beach near the now no longer freely accessible integrated into a high- voltage pylons all-round observation tower. Parking facilities in the eastern sea area complement the development. In the spring and autumn months, the fishing friends, trail hikers and occasional Rangers are around the lake to themselves. A sea circumnavigation is about 5 miles and takes about an hour.
