Character of the water

Kösjön lies in the cold north — a northern nutrient-rich lowland lake.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Shallow throughout (max 4 m), with reeds and vegetation over large areas — water that warms fast in spring.

Permits & rules

Fishing permit required — Kösjön FVOF. Day permit ~100 kr · annual permit ~500 kr.

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

Fishing Kösjön

Kösjön holds 5 species, with perch and pike at the top of the chain and roach, bream and ruffe schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Kösjön are alike.

General rules of thumb for this kind of water

  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
