Character of the water

Stora Kvarnsjön 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 (25 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Stora Kvarnsjön

perch, pike and zander sit at the top of the food chain in Stora Kvarnsjön, carried by ål, bream and roach. The clearer water makes the fish wary — and rewards a careful presentation.

Whoever fishes Stora Kvarnsjön 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.
