Character of the water

Koltjärn lies in the south — a southern clear oligotrophic forest 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.

Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Koltjärn

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
