The Riedbach is a mountain stream over 4.8 kilometers long in the Swiss canton of Valais . It is fed by the Ried glacier . The Riedbach is a mountain stream with a level-glacial runoff regime. Daily peak runoffs in summer reach around 4 m.
After exiting the glacier gate of the Ried glacier, the Riedbach flows over a glacier foreland with a channel slope of around 3%. After more than a kilometer it reaches a break in the gradient, the following section has a gradient of around 40%. After a further 500 m, most of the water for electricity generation is collected by Kraftwerke Mattmark AG .
The Riedbach flows north of St. Niklaus Dorf near the hamlet of Riedmatten into the Mattervispa , where it also forms the border to the hamlet of Lochmatten .
«Wasserleite» ( Suonen ) and hikes
Because the amount of precipitation in the Matter Valley is very low, profitable agriculture has always only been conceivable with brought water.
| «Water pipe» | description | Connection height | Final height | length | Difficulty of the hike | additional |
|---|---|---|---|---|---|---|
| "Wasserleita" Eggeri , formerly Bärgeri called | The «Wasserleita» Eggeri extends out of the valley towards the north to Grächen to Egga (district of Grächen) and Bärgji (hamlet northeast of Grächen) and is fully irrigated for agricultural use. | 1840 m , right side of the Riedbach | 1738 m | 6.2 km | The hiking trail along the Eggeri water line is marked and has a level of difficulty T1 . The ascent of the «Wasserleita» Eggeri can be combined with that of the «Wasserleita» Drieri . On the “Wasserleita” Eggeri, you can also enjoy the staged bisse experience “Magic Water”. | The "Wasserleita" Eggeri was built in 1603 when Gasenried signed a contract with Grächen for the use of water in the Riedbach. Regulations from 1618 have been preserved. Originally, the «Wasserleita» brought its water to the hamlets of Illas , Liechtbiel and Bheich as far as Stalden . The traces in this regard from the hamlet of Bärgji to the Äbibärg are still clearly visible today. |
| «Wasserleita» chilcheri | The «Wasserleita» Chilcheri extends out of the valley towards the north towards Grächen in the area of the church and is fully watered for agricultural use. | 1799 m , right side of the Riedbach | 1624 m | 3.9 km | The hiking trail along the «Wasserleita» Chilcheri is marked and has a level of difficulty T1. | The «Wasserleita» Chilcheri is mentioned in a contract from 1639 that stipulates the reopening of the «Wasserleita», which had previously stood idle. |
| «Wasserleita» Drieri | The «Wasserleita» Drieri extends out of the valley towards the north towards Grächen and is fully irrigated for agricultural use. | 1738 m , right side of the Riedbach | 1685 m | 3 km | The hiking trail along the «Wasserleita» Drieri is marked and has a level of difficulty T1. The ascent of the «Wasserleita» Drieri can be combined with that of the «Wasserleita» Eggeri . One arm of the Drieri flows to Gasenried and is called the twin sister or Ober Niwa . | The "Wasserleita" Drieri is mentioned in a historical document from 1618. |
| «Wasserleita» Bineri | The «Wasserleita» Bineri extends out of the valley in a northerly direction towards Grächen to Bina (district of Grächen) and is fully irrigated for agricultural purposes. | 1705 m , right side of the Riedbach | 1638 m | 3.2 km | The hiking trail along the «Wasserleita» Bineri is marked and has a level of difficulty T1. Some sections still run in historic Holzchännel. | The Bineri contract of 1603 allows the parts to build this "water duct" because they would have taken a "water duct" on the Riedbach a long time ago, but had to give it up due to the advancing Ried glacier. |
| «Wasserleita» matt water | The «Wasserleita» Mattwasser stretches above St. Niklaus Dorf first to the west and then into the valley to the south to Flur Balmu , which is located above the hamlets of Balacker ( 1177 m ) and Biffig ( 1272 m ) in the municipality of St. Niklaus. It is partly irrigated for agricultural use. | 1705 m , left side of the Riedbach | 1450 m | 3 km | The hiking trail along the «Wasserleita» Mattwasser is partially marked and has a level of difficulty T2. | Until 1942, the "Wasserleita" Mattwasser carried water to the hamlet of Mattsand . |
| «Wasserleita» Nieschwasser | The «Wasserleita» Nieschwasser stretches out of the valley to the north, past the Schalbett chapel, along today's road to Gasenried . | 1692 m , right side of the Riedbach | 1658 m | 0.5 km | ||

Kraftwerke Mattmark AG (KWM)
Kraftwerke Mattmark AG was founded in 1959. The feed tunnel of the Riedbach, which is 1808 m above sea level. M. to the east through the Mischabel massif into the pressure tunnel, is 5.1 km long and has a gradient of 3 ‰. The rake of the Riedbach version is 3.5 m wide and 8 m long. In 2008, the sand traps Schweiben was created, in a 1,000 m 3 large cavern filters the glacier water of Bach Ried and Schweibbachs. In 2009 the water intake of the Riedbach was expanded to a maximum water volume of 4 m 3 / s.
