The Beyenburger reservoir is one of the smallest dams in the Bergisches Land and is operated by the Wupperverband .
Location and description
The reservoir is located about eight kilometers south-east of Wuppertal- Barmen, directly in the Wuppertal district of Beyenburg . It lies in the valley of the Wupper , which is dammed here and is therefore by far the most important inflow of the reservoir. In addition, some small streams flow into the reservoir such as B. the Spreeler Bach . The cities of Wuppertal , Ennepetal and Radevormwald border the reservoir .
The reservoir has the shape of an "L" mirrored upside down. It is a good 1100 meters long and up to 140 meters wide; at its northeastern point it is up to 270 meters wide. The capacity of the reservoir is up to 465,000 cubic meters. Due to the sediments carried by the Wupper in the order of magnitude of up to 5000 m 3 per year, there is a risk of silting up in places, so that continuous dredging work is required.
The barrier structure of the barrage consists of a dam combined with a gravity dam , which serves as an overflow and flood relief . Part of the overflow is a 13 m wide weir with a lowerable segment closure. The height of the concrete wall is 8.6 meters above the foundation, its length 59 m. The total length with the dam is approximately 120 meters. Between June 2009 and autumn 2011, the Wupperverband carried out a thorough renovation of the dam wall, during which a fish ladder was built that enables the fish to overcome the barrier.
history
The Beyenburger reservoir was built in its present form between 1950 and 1953 and opened in 1954. In doing so, he enlarged the “ Beyenburg compensation pond ”, which was built between 1898 and 1900 and was no longer able to adequately fulfill its task as a flood protection system .
Both the previous building and today's reservoir were built for reasons of flood protection, especially in the parts of Beyenburg near the Wuppertal, as well as the increase in water during drier seasonal periods. However, this function has largely ceased to exist due to the construction of the Wuppertal Dam.
Todays use
The Beyenburger reservoir is now a popular local recreation area that is popular with both anglers and walkers. At the same time, the dam serves as a swimming lake in the summer months. Officially, however, this is not allowed and is also very dangerous due to deeper currents. A small hydroelectric power station also generates electricity. Its turbine is designed for a flow rate of 6.5 m³ / s.
Sporting use
On the eastern lakeshore belonging to Ennepetal are the club houses of several successful canoe clubs : the Wuppertal Canoeing Club ( VfK), the Wuppertal Canoe Club (WKC), the Wuppertaler Paddler-Gilde (WPG) and the Railway Sports Club Wuppertal-Ost . The three first-mentioned clubs form the Wuppertal Canoe Sports Association, which was the most successful German canoe racing club in the 1970s and 1980s and produced numerous World Cup and Olympic participants, including the later Olympic champion Ulrich Eicke . In recent times, the VfK dragon boat team, which goes under the name of Drag Attack Team , has made a name for itself with three world championships and numerous German championships.
On the west bank of Wuppertal is the boathouse of the water sports club Ennepetal , whose members use the lake for rowing .
The reservoir was also the venue for important canoe competitions such as the International Wuppertal City Regatta , which was held annually until the 1990s, and the German Canoe Polo Championships in 1971. Due to the increasing siltation of the lake and increasing growth of aquatic plants, it was used for competitive sports from the mid-1990s Years increasingly difficult, but more recently the Bergisch Dragon Boat Festival has established itself, which attracts five-digit visitor numbers to the reservoir year after year. In order to keep the lake usable for water sports, a mowing boat has been used since 2007, which regularly mows the water plants.
Tourist use
Especially because of the almost flat and rarely used paths that lead around the reservoir, it is often visited for walks, which are usually combined with a walk through the streets of Beyenburg. A Wuppertal provider has also been organizing Segway tours around the lake since 2016. The view over the eastern part of the lake to the monastery church of St. Maria Magdalena on the ridge above the Wupper is probably one of the most photographed images of Wuppertal.
The Wuppertaler Rundweg , the Wupperweg , the Residenzenweg , the Wappenweg and a route of the Westphalian-Rhenish Jakobsweg lead along the shoreline.
traffic
The state road 414 leads directly from Wuppertal-Barmen to Beyenburg. It runs together with the Wuppertal Railway, which runs parallel to the road over a railway bridge (in the form of a so-called fish belly bridge ) over the narrowest part of the lake, and continues as a road to Radevormwald; the railway line ends in Radevormwald-Wilhelmstal . Parking spaces near the reservoir are usually easily accessible. The center of Beyenburg and the reservoir can be reached regularly with the city bus routes. The Wuppertal Railway, which runs along the banks of the reservoir, only runs on certain weekends.
