Character of the water
Insjön lies in central Sweden — a mesotrophic stratified lake. In summer a thermocline settles around 6 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 (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing permit required — Insjön FVOF. Day permit ~60 kr · annual permit ~300 kr.
- Pike: keep at most one over 75 cm per day.
- Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Insjön
The species list of Insjön runs to 8. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.
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 Insjön are alike.
General rules of thumb for this kind of water
- Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
