Character of the water

Gröttjärnen lies in the cold north — a northern humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

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

Permits & rules

Fishing permit required — Gröttjärnen FVOF. Day permit ~100 kr · annual permit ~500 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 Gröttjärnen

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

Whoever fishes Gröttjärnen 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.
