Character of the water

Tretjärnavan lies in the cold north — a northern humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 6 m and splits the lake into two worlds.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

A small but surprisingly deep pocket (13 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Tretjärnavan FVOF. Day permit ~60 kr · annual permit ~300 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Tretjärnavan

The species list of Tretjärnavan runs to 3. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Whoever fishes Tretjärnavan 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
