Character of the water

Hagsjön 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 sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Hagsjön 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.

Species in Hagsjön

Down on the bottom ål sifts the soft ground — patience beats speed here.
pike predatory fish
typically ~62 cm · can reach 120 cm
Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
ruffe perch family
typically ~12 cm · can reach 22 cm

typically ~18 cm · can reach 32 cm

Fishing Hagsjön

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

Whoever fishes Hagsjön 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.
  • Acidified water yields few, hardy species.
