Gruvsjön

Character of the water

Gruvsjön lies in central Sweden — a 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 lies half-remote, a fair way from the nearest road, tucked into woodland.

Shallow throughout (max 2 m), with reeds and vegetation over large areas — water that warms fast in spring.

Permits & rules

Fishing permit required — Gruvsjön FVOF. Day permit ~60 kr · annual permit ~300 kr.

• Zander: minimum size 45 cm · protected during the spawn (Apr–May).
• Pike: keep at most one over 75 cm per day.
• Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
• Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Gruvsjön

Gruvsjön holds 14 species, with perch, pike and zander at the top of the chain and björkna, bream and elritsa schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Gruvsjön 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.
