Character of the water

Iresjön lies in central Sweden — a humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 9 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.

Large and deep (18 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Permits & rules

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

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

In the murky light, pike shadows the baitfish and hits in short rushes.
roach coarse fish
typically ~15 cm · can reach 26 cm
Roach grazes the rich water in schools — where there's one, there are more.

Fishing Iresjön

The species list of Iresjön runs to 4. 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 Iresjön 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.
  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
