Character of the water

Gopen lies in central Sweden — a clear oligotrophic deep lake. In summer a thermocline settles around 8 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.

Large and deep (30 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Permits & rules

Fishing permit required — Gopen 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.
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 Gopen

Gopen holds 13 species, with perch, pike and zander at the top of the chain and bream, ruffe and id schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Gopen are alike.

General rules of thumb for this kind of water

In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
