Character of the water
Ölsjön lies in central Sweden — a clear oligotrophic deep lake.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
A small but surprisingly deep pocket (25 m) with steep drops straight down from shore — the bottom falls away fast.

- Zander: minimum size 45 cm · protected during the spawn (Apr–May).

Fishing Ölsjön
perch, pike and zander sit at the top of the food chain in Ölsjön, carried by ruffe, roach and vendace. The clearer water makes the fish wary — and rewards a careful presentation.
Whoever fishes Ölsjön 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.
