Øvrevannsbrekket, or Oivus, is the top boundary for zone 4, and the spot is where the river runs out from Lake Øvrevann. From the road side, this place is accessible from two separate parking spots, and a path leads down to the top and bottom section of the pool. 

Early in the season, Oivus fishes best all the way to the top, but as the water receeds, the rapids forming below starts to look better and better. 

With a rather smooth glide, this is also a definite place for the bomber. The pool forming below the rapids, is also well-known to be a prolofic place for grayling.
