Wasserweg ansaina 9: Albula und Schaftobelbach

The Albula, which rises as a foaming spring on the Albula Pass, also gives the valley its name. It's only a short journey from the source to the stop in the shimmering blue Palpuogna Lake. With the construction of the railway, the hydropower of the water rushing down from Lake Palpuogna was used for the first time. After the gentle course of the water through the Preda valley step, it shoots through gorges, over waterfalls as well as under railway viaducts and engineering structures of the Albula road, to the Bergün valley level, where the river is tamed and the majority of the water is transported through a pressure tunnel, coordinated and monitored, into the "water castle" above Filisur. Once there, deep down in the Filisur valley, electricity is again generated by hydropower, the water is tamed again and turbinated for the third time in the Tiefencastel valley level. On its way to its confluence with the Hinterrhein, the Albula gains strength: among other things, through the water cascading over the towering waterfall of the Schaftobel.
