Character of the water

Lilla Ulvsjön lies in central Sweden — a 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 — Lilla Ulvsjön 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 Lilla Ulvsjön

Lilla Ulvsjön 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 Lilla Ulvsjön 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.
