Character of the water

Jan-Karlssjön lies in the south — a southern mesotrophic stratified lake. In summer a thermocline settles around 7 m and splits the lake into two worlds.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

A small but surprisingly deep pocket (13 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Jan-Karlssjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

Pike: keep at most one over 75 cm per day.
Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Jan-Karlssjön

perch predatory fish

typically ~22 cm · can reach 45 cm

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

pike predatory fish

typically ~62 cm · can reach 120 cm

Pike is a sight-hunter here — the clear water means long follows before the take.

roach coarse fish

typically ~18 cm · can reach 32 cm

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

ruffe perch family

typically ~12 cm · can reach 22 cm

Ruffe holds the bottom even in clear water — shade and depth are its cover.

burbot bottom fish

typically ~45 cm · can reach 90 cm

Burbot lives down in the cool — the deep is its home ground all year.

Fishing Jan-Karlssjön

Jan-Karlssjön holds 5 species, with perch, pike and burbot at the top of the chain and roach and ruffe schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Every session at Jan-Karlssjön 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.
