Character of the water

Stora Bosjön lies in central Sweden — a humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length.

The surroundings

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

A small but surprisingly deep pocket (19 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing permit required — Stora Bosjön 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 Stora Bosjön

Stora Bosjön holds 7 species, with perch, pike and burbot at the top of the chain and ål, löja and roach schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

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 Stora Bosjön are alike.

General rules of thumb for this kind of water

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
