Stora Önsjön

Character of the water

Stora Önsjön lies in the south — a southern mesotrophic stratified lake. In summer a thermocline settles around 8 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 (10 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Stora Önsjön 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.

Fishing Stora Önsjön

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

Every session at Stora Önsjön 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.
