The Elvegårdselva (also Skjoma ) is a river in the municipality Narvik in Nordland . It flows into the Skjomen fjord , a southern side fjord of the Ofotfjord , near Elvegård . It is 71 km long and has a catchment area of ​​844.34 km². The mean discharge at the mouth is 31.31 m³ / s. The river is numbered 738 in Norway's Vassdragsregister (register of watercourses). The Skjoma was one of the best salmon rivers in northern Norway before a hydroelectric power station was built in the 1970s. Since then the current has been greatly reduced, but the river still has a good stock of trout .

The longest tributary rises as an unnamed body of water on the southeast side of Storfjellet and flows as Sealggajohka from Lake Leirvatnet , follows the valley cut in northeast direction and then reaches the next lake, the Sealggajávri or Sælkajavrre. The Sealggajohka flows into Lake Čunojávri , into which the Rádjejohka also flows. The outflow from the Čunojávri is first called Čunojohka . This flows in a westerly direction into Norddalen. The river is only called Elvegårdselva or Skjoma when the Čunojohka and the Čáihnajoka coming from the south flow together. However, the river was slightly dammed after the confluence (reservoir 639 m above sea level); this reservoir is still called Čunojohka. At Alm Skearrogieddi, the water of the Lossivatnet lake flows from the north , which today serves as a reservoir. The Sorelva and Kobbelva flow into the river south of the Bogholm settlement, while the Elvegårdselva, coming from the east through Norddalen, changes direction almost at right angles to the north. Between Bogholm and Gamnes there is a measuring point (no. 739) for the discharge without a recording device.

In the Elvegårdselva catchment area there are a total of 79 glacier sections or permanent snow fields. Of these, Storsteinsfjellbreen is the largest glacier.

The area also has some artificially linked bodies of water. Part of the water from Sælkajavrre to Lossivatnet flows from there to Kobbvatnet . The dammed water from the Čunojohka also flows to the Kobbvatnet. The Kobbvatnet, in turn, is connected to the Iptovatnet , from where the pressure pipeline leads to the Skjomen power station (Skjomen kraftstasjon).
