Character of the water

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

Fishing Tretjärnarna

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

Every session at Tretjärnarna 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.

General rules of thumb for this kind of water

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