Character of the water

Gresjön lies in central Sweden — a 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 (16 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Gresjön FVOF. Day permit ~60 kr · annual permit ~300 kr.

  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Gresjön

The species list of Gresjön runs to 1. The predators — perch — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Gresjön is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

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.
