Character of the water

Kroksjön lies in central Sweden — a clear oligotrophic deep lake.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

A small but surprisingly deep pocket (39 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing permit required — Kroksjön FVOF. Day permit ~100 kr · annual permit ~500 kr.

Pike: keep at most one over 75 cm per day.
Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Kroksjön

perch and pike sit at the top of the food chain in Kroksjön, carried by björkna, bream and ruffe. The clearer water makes the fish wary — and rewards a careful presentation.

Whoever fishes Kroksjön 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

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