Character of the water

Illeråsasjön lies in the south — a southern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. Acidification has thinned life down to the hardiest few.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

A small but surprisingly deep pocket (18 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Illeråsasjön 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 Illeråsasjön

The species list of Illeråsasjön runs to 5. The predators — perch, pike and burbot — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Whoever fishes Illeråsasjön 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
  • Acidified water yields few, hardy species.
