Character of the water

Iso Syväjärvi 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.

Moderately deep (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing permit required — Iso Syväjärvi FVOF. Day permit ~60 kr · annual permit ~300 kr.

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.
