Character of the water

Grosjön lies in the south — a southern clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 6 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.

Shallow throughout (max 2 m), with reeds and vegetation over large areas — water that warms fast in spring.

  • Pike: keep at most one over 75 cm per day.
  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.

Fishing Grosjön

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

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 Grosjön are alike.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
