context_page_description: The Reuss is a river in Switzerland. With a length of 164 kilometres and a drainage basin of 3,426 square kilometres, it is the fourth largest river in Switzerland.
  The upper Reuss forms the main valley of the canton of Uri. The course of the lower Reuss runs from Lake Lucerne to the confluence with the Aare at Brugg and Windisch.
context_section_description: The Gotthardreuss rises in the Gotthard massif, emerging from Lago di Lucendro (reservoir built in 1947; elevation 2,134 m) in the canton of Ticino and passing into the canton of Uri at Brüggboden (1,910 m).
  The Furkareuss rises east of Furka Pass from Schwärziseeli and forms the valley called Urseren, passing Realp at 1,540 m.
  Gotthardreuss and Furkareuss join at Hospental (1,452 m). Downstream of Andermatt (1,432 m) the Reuss passes through Schöllenen Gorge and under the legendary Devil's Bridge. At Göschenen (1,102 m) it is joined by the Göschenerreuss. From here it forms the main valley of the canton of Uri, passing below Wassen (840 m), Gurtnellen (711 m), Silenen (500 m), and through Erstfeld (471 m), past Attinghausen and Altdorf (452 m), joining the southernmost part of Lake Lucerne (the Urnersee) at Seedorf (434 m).
  The Reuss leaves Lake Lucerne some 20 km to the north-west, at the city of Lucerne.
  Notable bridges in Lucerne are the Kapellbrücke, first built 1333, rebuilt 1993 and Spreuerbrücke, built 1408.
  A needle dam just upstream from the Spreuerbrücke) maintains the water level.
  It receives the Kleine Emme from Entlebuch at Emmen (432 m).
  From here, it flows north-east through Buchrain, Root, Gisikon and Honau, and downstream of Honau (402 m) leaves the canton of Lucerne, now forming the border between Aargau and Zug, passing 
  Dietwil (Aargau), Risch-Rotkreuz (Zug), Oberrüti (Aargau) and Sins (Aargau), Hünenberg (Zug) and Mühlau (Aargau). It receives the Lorze from Lake Zug downstream of Maschwanden.
  Downstream of this confluence, the Reuss forms the border between Aargau and Zürich, passing Merenschwand (Aargau, 389 m) and Ottenbach (Zurich, 384 m), and enters Aargau downstream of Ottenbach.
  Within Aargau, the Reuss flows past Aristau, Jonen, Rottenschwil, Unterlunkhofen, Hermetschwil-Staffeln, here forming Flachsee (380 m), and onward to Zufikon, Bremgarten (370 m). The Reussbrücke at Bremgarten was first built c. 1270, first mentioned 1281 (wooden bridge rebuilt 1953-1957).
  From Bremgarten, the Reuss meanders between the villages of Eggenwil, Fischbach-Göslikon, Künten, Niederwil, to Stetten (352 m), flowing past Tägerig, Mellingen (350 m), Birrhard (340 m), Mülligen, Birmenstorf and between Windisch and Gebenstorf, finally joining the Aare just downstream of Brugg, at 327 m.
  After the confluence the river continues as the Aare, which flows into the Rhine at Koblenz.
