City population: 485137
Duration: 2017 – 2018
Implementation status: Completed
Scale: Micro-scale: District/neighbourhood level
Project area: 55000 m2
Type of area: Public Greenspace Area

New recreation zone "Norikus Bay" in Nurenberg was completed in 2018 on the south bank of the Wöhrder lake, an artificial lake created in 1968 to protect the city from flooding. The dam itself, which is a 400m long path separating a part of the water surface from the bigger part of the lake, has become a tourist attraction with a water playground and other recreational amenities being offered. The water is naturally cleaned through the regeneration zone with natural plant filter, and simultaneously improves the habitat of fish and makes recreational swimming in possible in the cleaner water. New green areas are organized on the shore in order to improve environmental, aesthetic and recreational conditions of the area (1, 7, 8).

Project objectives

1. To create a new recreational area (1) 2. To sustain and enhance biodiversity (1) 3. Ecological improvement of the lake and surrounding areas (2) 4. To protect the city from flooding (2) 5. To improve the water quality in the lake (2) 6. To increase a flow velocity in the lake (2) 7. To reduce sludge deposition (2) 8. Improving the recreational quality of the shore surrounding the bay (7)

Implementation activities

1. A 400-meter long dam was created, separating a part of the water surface from the bigger part of the lake (1) 2. Reed plants for natural water filtering were planted (1) 3. New trees and greenery were planted on the shore (1) 4. A barrier-free access to water and recreational facilities were provided (1) 5. Benches and walkways were arranged (1) 6. A solid spillway was erected in order to allow water and fish to move freely (2) 7. 300,000 cubic meters of mud were removed from the bottom of the lake (3) 8. A water playground was created on the dam (8)

Biodiversity conservation or restoration-focused activities

Biodiversity conservation:

Details on the roles of the organisations involved in the project

The project was initiated and led by the local government. The company GAUFF Engineering was commissioned by the Water Management Office Nürnberg (Wasserwirtschaftsamt Nürnberg) to prepare and implement the construction measures for the "Wöhrder See Water World" at Norikus bay. (4) The reconstruction of the bay was funded by the state of Bavaria, while the recreational facilities financed by the city of Nurnberg (5)
