Character of the water

Rocksjön lies in the south — a southern mesotrophic stratified lake. In summer a thermocline settles around 7 m and splits the lake into two worlds.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Moderately deep (11 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Rocksjön

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

Whoever fishes Rocksjön 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

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
