The bye river flows into the municipality of Arvidsjaur, in the lake-rich forest and marshland north of Storavan and the mouths of Bottenviken at Byske in Skellefteå municipality. The highest coastline (your sea reached the highest during or after the last ice age) is passed approximately at Nyfors, one mile downstream of the Mooring. The bottom part, from Bjørsel til havet, falls about 38 meters in 11 kilometers.

Of the 3 662 km² of the catchment area are 2,792 km² (76%) in Norrbotten County and the rest in Västerbotten County.

As a source of flow, the Järfer river is counted, where the lakes Västra Järfojaur and Östra Järfojaur are found in the upper part. Järferälven flows through Västra Kikkejaure and opens in Arvidsjaursjön. There also the Långskilskälven (as above Langångsket is called Allejaurälven) and Svärdälven opens. Downstream Arvidsjaursjön are the most important tributaries counted alongstream is Kelisån (with the Great Lakes Pjesker and Gråträsket), Bäverån, Långträskån, Ålsån and Tværån.

Byskio means "the swelling" and refers to the cool variations in the watercourse that arise as a result of the low lake percentage below the source lakes.

In Långträskån there were 5 control ponds from Banfors to the power station in Myrheden. Today, all obstacles are gone.
