Sädvvájávrre, or Sädvajaure, is a lake in Arjeplog Municipality in the province of Lapland, which is part of the main catchment area of the Skellefte River.

Sädvvájávrre is used as a water reservoir for long-term regulation of hydroelectric power production in the almost completely developed Skellefteälven.

[1] On the south side of Sädvvájávrre, near the outlet of the Silbbajåhkå watercourse, there was a foundry belonging to the Nasa silver mine between 1635 and 1659.

Towards the east, the presence of pine increases, and sometimes there are even small stands, but almost all the trees have grown after the end of the Nasafjäll era.

After it burned down in 1747, a temporary place of worship was set up, and the Sami continued to hold summer services in Silbojokk.

Since there was no longer any usable timber forest around Sädvvájávrre, a new chapel was built in 1777 in Lövmokk, just north of Jäkkvik.

[5] Following the raising of the dam limit in 1985, the hut area was subjected to heavy water and ice impact every year.

[6] Another survey was conducted in 2015, during which the extent of the cemetery could be better delineated, and almost 250 loose finds were discovered in the swelling ground, mostly nails but also human bones, window glass, and lead.

The catchment area has 40.38 square kilometers of water surface, giving it a lake percentage of 30.9 percent.
