The Marsyangdi ( Nepali : मर्स्याङ्दी , marsyāṅdī ) is a river in central Nepal .
It has a length of about 150 km, rises in the northeast of the Annapurna massif at an altitude of about 3600 m with the two source rivers Khangsar Khola and Thorong Khola (also Jharsang Khola ) and flows into the Trishuli at Mugling . The river flows around the east side of the Annapurna massif through the districts of Manang and Lamjung and separates it from the Manaslu massif . The valley of the Marsyangi is followed by part of the Annapurna circular route ( Annapurna Circuit ) and the Manaslu circular route ( Manaslu Circuit ).
The largest town on the Marsyangdi is Besisahar ( 780 m ). Other well-known places are Manang ( 3550 m ), Pisang ( 3300 m ) and Chame ( 2700 m ).
Hydropower
On the lower reaches of the Marsyangdi near Ambukhaireni ( 348 m ⊙ ) an 89 MW hydropower plant was built in 1990. The water is dammed up and fed through a tunnel to the turbine works ( 280 m ⊙ ) 13 km downstream, which means that almost all of the water is withdrawn from the river in the dry season (September to June) on this stretch.
A second power plant ( Middle Marsyangdi HEP ; 70 MW) was built in 2009 on the middle reaches about 6 km south of Besisahar ( 610 m ), which works on the same principle; the inlet is 7.7 km downstream ( 534 m ⊙ ). The power plant has to be shut down frequently because the river does not carry enough water in the dry season.
A third power plant ( Upper Marsyangdi-2 HEP ; run-of-river power plant with 600 MW) is currently being built on the border of the Manang and Lamjung districts . The project should be completed in 2016. It comprises a 145 m long and 31 m high earth embankment ( ⊙ ). The design flood is 4066 m³ / s. A 9.2 km long headrace tunnel with a diameter of 6 m leads the water to the power plant (4 units of 150 MW each). The height of fall is 627.67 m.
leisure
The Marsyangdi is one of the more well-known rivers for white water descents ( kayaking and rafting ) with levels of difficulty from 4+ to 5-.
