Character of the water

Jämnsjön lies in central Sweden — a clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 4 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.

Moderately deep (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Jämnsjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

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

Fishing Jämnsjön

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

Every session at Jämnsjön 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.
