Character of the water

Stora Sirsjön lies in central Sweden — a clear oligotrophic deep lake.

The surroundings

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

A small but surprisingly deep pocket (31 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing permit required — Stora Sirsjön FVOF. Day permit ~100 kr · annual permit ~500 kr.

Zander: minimum size 45 cm · protected during the spawn (Apr–May).
Pike: keep at most one over 75 cm per day.
Handheld tackle only. Respect the protected zones at the inlets and outlets.

Here roach lives on the small stuff — and rewards those who fish small and fine.

Fishing Stora Sirsjön

Stora Sirsjön holds 6 species, with perch, pike and zander at the top of the chain and roach, bream and ruffe schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Every session at Stora Sirsjön 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

In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
