Brabrand Lake (Danish: Brabrand-søen or Brabrand Sø) is a lake in the district of Brabrand (Gellerup), west of Aarhus city, Denmark. The Aarhus River passes through Brabrand Lake and it is possible to canoe all the way to the inner city from here. The lake is oblong-shaped.

Within the last decade, Brabrand Lake has steadily been extended 3–4 km further west, with the new lake of Årslev Engsø (lit.: meadow lake of Årslev). It was politically decided, to abandon the artificial draining of the meadows and as of 2013, Årslev meadow lake has a surface area of around 100 hectares (250 acres). The total area including the adjoining meadows and reed beds sums up to 240 hectares (590 acres). It is expected that Eurasian bittern and otter, will find themselves a new home here with time.[1] In everyday parlance, "Brabrand Lake" is a general term including the surroundings as well, indicating a total area of around 560 hectares (1,400 acres) with 253 hectares (630 acres) for the lake alone.

A special Natura2000 protected area under the European Union,[2] Brabrand Lake is home to a large variety of birds and an important resting-place for migrating birds,[3] with several towers built to facilitate bird-watching. A public hiking trail surrounds the lake, whose landscape varies from wide meadows and reed beds to dense woods. The lake brinks is occupied by privately owned pastures, almost all the way around the lake and is not publicly accessible. There are public paths leading to the lake itself scattered in between, though. There are several alottments nearby. It is a popular recreational area and it is a statutory goal of the Aarhus municipality to make it publicly accessible and attractive for the citizens.[4]

Activities and sports[edit]

The pathway of Brabrandstien (1956), runs from the inner city of Aarhus, encircling both of the lakes. It is c. 30 km long.

The pathway of Brabandstien (lit.: the Brabrand pathway) running along the Aarhus river from the inner city and around the lakes, was established by the City Council in 1956, to give the citizens better access to the green areas here. The pathway is 19 km long, with 10 km for the Brabrand Lake alone. With the addition of Årslev Engsø, the pathway grew with another 10 km. A large part of Brabrandstien is asphalted and is popular with cycling, rollerskating and jogging and some of the gravelled western parts are used for horse trotting. Cars are not allowed and motor vehicles are restricted. Brabrandstien is part of the Aarhus-Silkeborg hiking trail.[5][6][7]

On the northern banks of Brabrand Lake, lies the facilities of Brabrand Rostadion (Brabrand Rowing Stadium). The stadium was established in 1952 and has recently been heavily renovated and rebuild in the year 2010. C. F. Møller Architects was the architectural firm behind the new buildings.[8] Local rowing and kayaking clubs have used the lake for practicing and larger regattas for many years and now Rocenter Aarhus RCA (Rowingcentre Aarhus) are here, offering qualified training for rowers and clubs in East and South Jutland on all levels (including elite) and for all ages. There is a 2.000 m racing track on Brabrand Lake and it is generally perceived as very good for outrigger racing, but other boat-types are being rowed here as well, including kayaks.[9][10][11] Aarhus Roklub (Aarhus Rowing Club) have scored several prestigious medals. In 2005 Maria Pertl won silver in the World Rowing Championships in collaboration with Juliane Elander Rasmussen. In 2011 Andrej Lawaetz Bendtsen won gold at the WRC for seniors in a team of 4.[12]

Environmental projects[edit]

The lake is not very deep and has suffered from eutrophication for many years. The excessive nutrients originates from waste water and agricultural activities and poses a constant environmental threat to the surrounding ecology and the Bay of Aarhus. Eutrophication is a common problem all over the developed world. Starting in 1959 with 158 hectares, several environmental projects has aimed at alleviating the environmental burdens and at the same time maintaining the aesthetic value of the lake and surroundings. These projects includes mud pumping of the lake floor and willow afforestations. It is hoped that the rich fen ecology, that formerly characterized the lake and is a threatened type of nature, can be restored in the future.[2][13][14]

The groundwater beneath and adjoining Brabrand Lake, is very important, as it provides drinking water to more than 100,000 people in the greater Aarhus area. Acting partly on this fact, the lake water is also included in a large water treatment project lead by the Aarhus Vand A/S (Aarhus Water) company. The project involves the Brabrand Lake, the Aarhus River and the Aarhus Bay and is budgeted at 45 million. The project is almost finished as of 2013.[15][16]

Special flora and fauna[edit]

Many species of flora and fauna at Brabrand Lake, are either rare or relatively rare in Denmark and on the Danish Red List (under IUCN Red List). Some are also protected under different habitat directives of the EU. Here is a few examples:[3]

Apart of the specialities, the Brabrand Lake area is characterized by the many common species living here. Mostly birds, insects and aquatic plants.

Archaeological finds[edit]

The area around Brabrand Lake have been populated for at least 6-7,000 years. In prehistoric times, Brabrand Lake was part of a deep brackish water fjord, offering natural protection and food in abundance. There were archaeological excavations here as early as 1903, revealing early Stone Age settlements and activities from the Ertebølle Culture. The Brabrand Lake area is still an active archaeological site today and have revealed Bronze Age settlements and Viking activities like a large shipbuilding yard. [19] [20] [21]
