Character of the water

Grundasjön lies in the south — a southern humic brown forest lake. The water is crystal-clear and the fish skittish in the sharp light.

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.

A small but surprisingly deep pocket (13 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Grundasjön FVOF. Day permit ~60 kr · annual permit ~300 kr.

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

Roach grazes the rich water in schools — where there's one, there are more.
vendace whitefish

Burbot works the bottom in the dark — smell and feel come before everything else.

Fishing Grundasjön

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

Every session at Grundasjön 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.
