The Galtera , partly also Galternbach , called Gottéron in French , is an approximately 17 km long right tributary of the Saane ( Sarine in French ) in the Swiss canton of Friborg . It drains a section of the higher Freiburg Central Plateau and belongs to the catchment area of the Rhine .
course
The headwaters of the Galtera are located at around 1000 m above sea level. M. in the foothills of the Alps on the municipality of Plaffeien , on the slope of the Oberholz (district Oberschrot ). As a small trickle, the stream initially flows north and reaches a wide valley basin south of Alterswil . Here the Galtera draws an arc and turns to the west. At Alterswil it gradually begins to deepen into the surroundings, but for the time being it still has a 100 to 200 m wide flat valley floor in which it moves with many short meanders .
At Ameismühle south of Tafers the Galtera joins the Tasbergbach coming from the south , its most important tributary . Then it flows through the Galterengraben , a 3 km long gorge cut up to 100 m into the surrounding high plateaus, the flanks of which are formed by steep slopes with sandstone cliffs . Shortly before it flows into the Saane, the Gottéron Bridge spans the Galtera valley. At 535 m above sea level M. the Galtera flows into the Saane opposite the old town of Freiburg . In the middle and lower reaches the brook has a mean gradient of 2%.
Large sections of the Galtera are still in their natural or near-natural state. The Galtera is characterized by a pluvial runoff regime . In the past, their water power was used in various places to operate mills and sawmills. At the confluence of the Galtera with the Saane , the city of Freiburg built a bridgehead in the Middle Ages . Walks, mills, saws, hammer and grinding mills settled along the lowest section of the river, so that this quarter developed into a real industrial zone of what was then Freiburg.
The Galtern Gorge, through which a hiking trail leads today, is worth visiting. The Friborg-Gottéron ice hockey club is named after the French name of the river.
