Character of the water

Grundsjön lies in central Sweden — a clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

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

Large and deep (27 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Permits & rules

Fishing permit required — Grundsjön 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.

In the clear water pike picks its moments — wary, but relentless once committed.
roach coarse fish
typically ~18 cm · can reach 32 cm
Roach moves carefully in the clear water — small mouthfuls, many of them.
vendace whitefish

Fishing Grundsjön

The species list of Grundsjön runs to 4. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Grundsjön 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.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
