Character of the water

Tvingen lies in the south — a southern clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

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

Large and deep (29 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 — Tvingen FVOF. Day permit ~60 kr · annual permit ~300 kr.

Pike: keep at most one over 75 cm per day.

Fishing Tvingen

Tvingen holds 9 species, with perch and pike at the top of the chain and björkna, bream and ruffe schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Whoever fishes Tvingen 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

Clear water makes fish light-shy — dawn, dusk and night are usually best.
In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
