Character of the water

Hasselasjön 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.

Moderately deep (17 m) — shallow bays, the odd reef and a deeper channel through the middle.

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

  • Zander: minimum size 45 cm · protected during the spawn (Apr–May).
  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Hasselasjön

The species list of Hasselasjön runs to 10. The predators — perch, pike and zander — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Whoever fishes Hasselasjön 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.
