After more than two centuries as drained farmland, Søborg Lake in North Zealand is being restored as one of the region's largest nature projects. On September 30, the pumps that have kept the land dry since the late 1700s will be switched off, allowing water to flow back into the 600-hectare area. Within a year, the lake will stretch across more than 300 hectares, surrounded by meadows and rich wildlife.
The project, led by the Danish Nature Agency, includes dikes, inlets, and new wetlands that will attract waders, waterfowl, and birds of prey, with a special focus on the rare corncrake. Fish such as perch, pike, and roach are expected to return from nearby streams.
Beyond nature, the restoration will cut nitrogen runoff into the Kattegat by 20 tons annually and reduce CO₂-equivalent emissions by 8,500 tons, helping Denmark's climate goals.
The area will also be opened to the public with 13 km of new trails for hiking, cycling, and riding. Visitors will again see the medieval ruins of Søborg Castle reflected in the water, linking natural and cultural heritage.
The project cost 126 DKK million and involved voluntary land redistribution among local landowners. The official reopening will be marked on September 30 with an event attended by Green Tripartite Minister Jeppe Bruus.
