Character of the water

Stortjärnen lies in the cold north — a northern 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 (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Stortjärnen 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 Stortjärnen

perch predatory fish
typically ~22 cm · can reach 45 cm
The nutrient-rich water keeps perch moving constantly between the feeding grounds.
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.

Fishing Stortjärnen

perch and pike sit at the top of the food chain in Stortjärnen. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Every session at Stortjärnen 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.
  • Acidified water yields few, hardy species.
