Character of the water

Borgtjärnen lies in the cold north — a northern 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 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.

Moderately deep (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Borgtjärnen FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Borgtjärnen

Borgtjärnen holds 1 species, with perch at the top of the chain. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Borgtjärnen 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.
