Költjärnen

Character of the water

Költjärnen 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 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.

Permits & rules

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

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

Fishing Költjärnen

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

Every session at Költjärnen 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

• Brown, humic water dampens the light — fishing can be good even in the middle of the day.
• Acidified water yields few, hardy species.
