Ovelo - Around Bütgenbach Lake

Walking ·

Taking the Ravel L45a, we head towards Weywertz to the Vennbahn, which leads us to a landscape of fields and meadows further to the north. Following the curve of the path, past Nidrum and Elsenborn, we catch sight of the lake in Berg. We reach Wirtzfeld along deserted paths. There, the journey back to Bütgenbach starts.

The Italian engineer Boldo had a 23-metre-high dam built in the Warche valley between 1930 and 1932 in order to generate electricity via a turbine, which produces 2 million kWh a year. Since the lake, spanning 120 hectares (296 acres), is not used for drinking-water, all kinds of water sports are possible. In the summer you can swim, sail or enjoy a pedal boat ride here to your heart’s content. The tour starts on the Ravel L45a. You can just about make out the lake between the trees and bushes. The countryside opens up beyond the lake at the level of the railway viaduct, which towers above the Warche valley. After a few kilometres, the Vennquerbahn merges with the Vennbahn, which you follow for some five kilometres along the village limits of Weywertz.

Past cows and pastures and so few houses that they can be counted on the fingers of two hands, you reach the village of Berg after 13 kilometres. You can catch an occasional glimpse of the lake. Wirtzfeld is situated at the eastern end of the reservoir. You pass the village centre on your left. One last hill and you cross the Holzwarche and the Warche, both of which supply the reservoir with water.
