From farmland to new nature

Filsø is dewatered 

From 1852 until after World War II, Filsø lake was progressively dewatered in order for the lake to be converted into farmland.

Initially, the purpose was to create areas for hay harvest but, later on, people also began to grow various crops on the land, including grain, seed grass and potatoes. In 1950, the grain dryer and the large barns were built and, at the time, they constituted the largest agricultural buildings in Northern Europe. Filsø evolved into an ultramodern farm, and it was one of the largest in Denmark with 1,200 hectares under the plough.

The Land Reclamation Era

In the mid-1800s, the “Land Reclamation Era” started in Denmark. The desire for larger agricultural areas, food security and increased employment provided the opportunity to obtain state aid for land reclamation projects. Changing legislation allowed for e.g. dewatering of lakes, drainage of wetlands and diking of coastal areas.

The map of Denmark changed dramatically up until the late 1960s when the last major project, the straightening of the river Skjern Å, ended the land reclamation era.

The new Filsø is created

In 2010, the company that owned Filsø sold the entire property of 2,300 hectares to Aage. V. Jensen Naturfond for the purpose of nature restoration of Filsø. In connection with the nature restoration of Filsø, buildings were demolished, as they no longer served any purpose. Furthermore, a pig farm and 4 slurry tanks were removed. They were located on Dæmningsvejen, some ½ km west of where you are standing right now. The demolition material has been reused as road fill on the property. Only the weigh house still stands on Dæmningsvejen, some ½ km west of where you are standing right now.

Facts:

  • There were about 70 km of ditches and drainage canals on the farmland
  • There were about 40 km of roads on the farmland
  • There were about 600 km of drainage pipes laid on the farmland
