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.

Shallow throughout (max 3 m), with reeds and vegetation over large areas — water that warms fast in spring.

  • Pike: keep at most one over 75 cm per day.

General rules of thumb for this kind of water

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