Ostjärnen

Character of the water

Ostjärnen lies in central Sweden — a mesotrophic stratified lake. In summer a thermocline settles around 9 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.

A small but surprisingly deep pocket (21 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

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

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

Fishing Ostjärnen

perch and pike sit at the top of the food chain in Ostjärnen, carried by roach. 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 Ostjärnen are alike.

General rules of thumb for this kind of water

• In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
