Character of the water

Björnsjön lies in central Sweden — a acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. Acidification has thinned life down to the hardiest few.

The surroundings

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

Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Björnsjön

Björnsjön holds 1 species, with perch at the top of the chain. 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 Björnsjön 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.
  • Acidified water yields few, hardy species.
