Character of the water

Betarsjön lies in the cold north — a northern clear oligotrophic deep lake. In summer a thermocline settles around 12 m and splits the lake into two worlds.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Large and deep (43 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Permits & rules

Fishing permit required — Betarsjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Betarsjön

perch, pike and burbot sit at the top of the food chain in Betarsjön, carried by ruffe, roach and nors. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Betarsjön is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

General rules of thumb for this kind of water

  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
