Character of the water

Kolatjärnen 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 (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Kolatjärnen FVOF. Day permit ~100 kr · annual permit ~500 kr.

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

Species in Kolatjärnen

perch predatory fish
typically ~22 cm · can reach 45 cm
The nutrient-rich water keeps perch moving constantly between the feeding grounds.
pike predatory fish
typically ~62 cm · can reach 120 cm
Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.

Fishing Kolatjärnen

Kolatjärnen holds 2 species, with perch and pike at the top of the chain. The modest depth keeps most of the fishing within reach of the bank.

Every session at Kolatjärnen 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.
