Trudlerbaach
To the South of Lac Beriton the Trudlerbaach begins narrow flowing through a narrow channel at the border of the Schältgen. It is next to a small unpaved pathway which marks the border between the Sauerfeld and the Schälgen. Eventually it flows towards Beriton and crosses under a pathway used for access to the shooting lodge through a culvert. Further south the Trudlerbaach nears the southern end of the Shältgen and begins to broaden and deepen. The river flows much slower relative to just south of Lac Beriton. Eventually the river narrows once more and becomes very shallow to the point where the water ripples as it flows. By this point the river has left the Shältgen and now forges the border between the Sauerfeld and am Grond. Eventually the path it has been parallel to ends and the river flows directly through one of the fields in the Sauerfeld. At the end of the path, the stream crosses directly under a fence dividing plots of land. The Trudlerbaach soon after begins to split into several small channels separated by large sedge plants and at one point the path of the stream forges and island. Further south the Trudlerbaach crosses through another culvert which links a field in the Southern Sauerfeld and am Grond.
