𝐆𝐞𝐬𝐜𝐡𝐢𝐜𝐡𝐭𝐞 𝐍𝐨𝐬𝐰𝐞𝐧𝐝𝐞𝐥𝐞𝐫 𝐒𝐞𝐞 The lake has a size of 6.6 ha. It was dammed in 1979 and is fed by the water of the Wahnbach. The Wahnbach, which rises near the Pascalhütte on the state border of Saarland and Rhineland-Palatinate near Steinberg, flows north of Büschfeld into the Prims. The reservoir is the heart of the 20-hectare leisure center of the same name. Due to the strong commitment of the local associations, which are organized in the local history and tourist association, catering by the lake and a well-filled calendar of events are guaranteed in the summer season.
