Character of the water

Idresjön lies in central Sweden — a clear oligotrophic forest lake. In summer a thermocline settles around 12 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.

Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

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

Pike: keep at most one over 75 cm per day.
Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Idresjön

typically ~13 cm · can reach 32 cm

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

trout salmonids

typically ~8 cm · can reach 8 cm

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

whitefish whitefish

typically ~24 cm · can reach 49 cm

Whitefish cruises the open water — the depth it picks follows the light through the day.

Fishing Idresjön

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

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 Idresjön are alike.

General rules of thumb for this kind of water

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