Character of the water

Lilla Bosjön lies in central Sweden — a mesotrophic stratified lake. In summer a thermocline settles around 7 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.

Zander: minimum size 45 cm · protected during the spawn (Apr–May).

Fishing Lilla Bosjön

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

Every session at Lilla Bosjön 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

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
