Character of the water

Mjörn lies in the south — a southern mesotrophic stratified lake. In summer a thermocline settles around 28 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.

Large and deep (48 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Fishing Mjörn

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

Every session at Mjörn is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.
