It runs from the lake Reisavannet in Nordreisa Municipality through the Reisa Valley and empties into the Reisafjorden in Kåfjord.

[3][5][6] Multiple fish in the river weighing over 20 kilograms (44 lb) have been caught.

[6][7][8] A total of 481 kilograms (1,060 lb) of salmon, sea trout, and char were caught in 2019.

[3] In Northern Sami, the river is called “Raisjohka,” which is a compound word made up of “rais” and “johka.” “Rais” means “flat” or “level,” while “johka” means “river.” Therefore, “Raisjohka” roughly translates to “flat river” in English.
