Character of the water

Stugusjön lies in the cold north — a northern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 7 m and splits the lake into two worlds. 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 (11 m) — shallow bays, the odd reef and a deeper channel through the middle.

Species in Stugusjön

perch predatory fish
typically ~22 cm · can reach 45 cm
The nutrient-rich water keeps perch moving constantly between the feeding grounds.

Elritsa grazes the rich water in schools — where there's one, there are more.

typically ~12 cm · can reach 22 cm

burbot bottom fish
typically ~45 cm · can reach 90 cm
Down on the bottom burbot sifts the soft ground — patience beats speed here.
roach coarse fish
typically ~18 cm · can reach 32 cm
The nutrient-rich water keeps roach moving constantly between the feeding grounds.

typically ~35 cm · can reach 70 cm
Trout hunts by feel more than sight in the stained water — short, hard strikes close to the bait.

typically ~35 cm · can reach 70 cm

whitefish whitefish

Fishing Stugusjön

perch, pike and burbot sit at the top of the food chain in Stugusjön, carried by elritsa, ruffe and roach. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Whoever fishes Stugusjön 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.
