The river generally flows north and it runs through the large lake Einavatnet as it passes through the municipalities of Hurdal, Vestre Toten, and Gjøvik.

The mouth of the river is in the town of Gjøvik where it empties into the large lake Mjøsa.

The main part of the river is about 23-kilometre (14 mi) long and it runs from the Einavatnet lake to the town of Gjøvik.

"[11][12] This greatly affected the level of pollution in Lake Mjøsa and by the end of the 19th century, the wildlife had been decimated.

[11] The river is now home to trout, perch, pike, whitefish, rudd, and minnows.
