Character of the water

Grössjön lies in the cold north — a northern acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. 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.

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

Permits & rules

Fishing permit required — Grössjön 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.

Species in Grössjön

perch predatory fish
typically ~22 cm · can reach 45 cm
Perch moves carefully in the clear water — small mouthfuls, many of them.
pike predatory fish
typically ~62 cm · can reach 120 cm
In the clear water pike picks its moments — wary, but relentless once committed.

Fishing Grössjön

perch and pike sit at the top of the food chain in Grössjön. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Grössjön 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • Acidified water yields few, hardy species.
