Character of the water

Sundsjön lies in central Sweden — a clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light.

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.

Large and deep (35 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 — Sundsjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

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.

Species in Sundsjön

typically ~22 cm · can reach 45 cm

Ål lives down in the cool — the deep is its home ground all year.

whitefish whitefish

typically ~30 cm · can reach 55 cm

Fishing Sundsjön

Sundsjön holds 9 species, with perch, pike and grayling at the top of the chain and ål, regnbåge and whitefish schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Whoever fishes Sundsjön 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.
