Character of the water

Berttjärnen lies in the south — a southern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. Acidification has thinned life down to the hardiest few.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Berttjärnen 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 Berttjärnen

The species list of Berttjärnen runs to 2. 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 Berttjärnen 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.
  • Acidified water yields few, hardy species.
