The Alpbach (in the upper reaches of Fulbach) is an approximately ten kilometer long left tributary of the Reuss in the area of ​​the municipality of Erstfeld in the Swiss canton of Uri .

course

The river rises as Fulbach at about 2512  m above sea level. M. below the Glatt Firn on the southeast slope of the Graw Stock . After the confluence of some source streams, it flows into the Obersee . He leaves the mountain lake and at the same time overcomes an 80 meter and a 20 meter high waterfall before reaching a relatively flat, swampy plain. Here it passes the Fulensee and then falls 90 meters down a valley step, where it joins the somewhat larger Sunnig Grundbach to form the Alpbach at the beginning of the Erstfeldertal . The Alpbach now flows to the east through a narrow gorge, before it crosses the meadows of Noflenberg, Bodenberg, Restiberg, Ribiberg, Sagerberg and Plattenberg. After a second passage through the gorge, it reaches the alluvial fan in the Reuss valley and crosses the Taubach tunnel on the A2 . It finally flows into the village of Erstfeld at 467  m above sea level. M. into the Reuss.

At the hamlet of Bodenberg, the Chesselbach and the Eienbach, which rises below a high rock step near the Leidsee, flow into the Alpbach from the south .
