Character of the water
Ösjön lies in central Sweden — a nutrient-rich lowland lake.
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.

Fishing permit required — Ösjön 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 Ösjön
The species list of Ösjön runs to 5. 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 Ösjön are alike.
General rules of thumb for this kind of water
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
