Character of the water

Fioltjärnen 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 11 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 — Fioltjärnen 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 Fioltjärnen

perch and pike sit at the top of the food chain in Fioltjärnen, carried by roach and whitefish. The clearer water makes the fish wary — and rewards a careful presentation.

Whoever fishes Fioltjärnen 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.
