Character of the water

Fjällsjön lies in central Sweden — a clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light.

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.

A small but surprisingly deep pocket (30 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Fjällsjön FVOF. Day permit ~140 kr · annual permit ~700 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.

Fishing Fjällsjön

Fjällsjön holds 8 species, with perch, pike and burbot at the top of the chain and ål, löja and roach schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Whoever fishes Fjällsjön regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

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.
