Character of the water

Jon-Jansatjärnen lies in the cold north — a northern 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 (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Jon-Jansatjärnen

perch, pike and trout sit at the top of the food chain in Jon-Jansatjärnen, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.

Whoever fishes Jon-Jansatjärnen 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.
