In 1979, the Wölferlinger Weiher was designated an official nature reserve.

Laid out along with six other ponds by Count Frederick III of Wied in the 17th century, the Wölferlinger Weiher is part of the protected landscape known as the Westerwald Lake District.

The Wölferlinger Weiher itself has an area of 1.02 hectares and is thus much smaller than the other waterbodies of the Westerwald Lake District.

It is home to rare bird and plant species such as Jacob's Ladder and lesser butterfly-orchid.

[2] The lake has marshes and shallow water zones along its perimeter.
