Character of the water

Vassjön 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 remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Shallow throughout (max 3 m), with reeds and vegetation over large areas — water that warms fast in spring.

Fishing Vassjön

perch, pike and zander sit at the top of the food chain in Vassjön, carried by asp, bream and ruffe. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Whoever fishes Vassjön 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.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
