Character of the water
Kollsjön 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.
A small but surprisingly deep pocket (28 m) with steep drops straight down from shore — the bottom falls away fast.
Permits & rules
Fishing permit required — Kollsjön FVOF. Day permit ~60 kr · annual permit ~300 kr.
- Handheld tackle only. Respect the protected zones at the inlets and outlets.

Regnbåge is a sight-hunter here — the clear water means long follows before the take.

Whoever fishes Kollsjön 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.
