Character of the water

Björnsjön lies in the south — a southern nutrient-rich lowland lake. In summer a thermocline settles around 5 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 (11 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Björnsjön

Björnsjön holds 7 species, with perch, pike and zander at the top of the chain and roach, bream and ruffe schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Björnsjön are alike.

General rules of thumb for this kind of water

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
Nutrient-rich lakes hold plenty of baitfish but often murky water.
