Character of the water

Gäsjön lies in central Sweden — a clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 10 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 (25 m) with steep drops straight down from shore — the bottom falls away fast.

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.

Fishing Gäsjön

perch, pike and grayling sit at the top of the food chain in Gäsjön, carried by bream, id and 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 Gäsjön are alike.

General rules of thumb for this kind of water

Clear water makes fish light-shy — dawn, dusk and night are usually best.
In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
