As a result, the river remains under the influence of natural forces; for example, the tides in the bay affect both water level and flow rate far upriver, often as far as the outflow from Lake Karlsgårde.

[1][2][3] The lower river valley, west of Varde, was previously under intensive cultivation, among other uses for the production of horse feed with EU support.

Beginning in 1994–95, farmers have modified their practices, no longer using fertiliser and keeping vegetation cut, which it is hoped in association with the higher water table will restore habitat for birds, in particular the endangered corncrake.

[4] The Varde River together with the lower reaches of the Ansager and the Grindsted has been designated an EU Special Area of Conservation.

In the designation, the houting and the freshwater pearl mussel were identified as priority species; especial weight is to be given to fulfilment of provisions relating to their habitat.

In addition to fishing, Varde Roklub uses the river for rowing between April and October on the stretch between the Karlsgårde Hydroelectric Plant and the Tarphage bridge near Billum.
