Stor-Ådertjärnen

Character of the water

Stor-Ådertjärnen lies in central Sweden — a 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.

A small but surprisingly deep pocket (16 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Stor-Ådertjärnen

perch, pike and grayling sit at the top of the food chain in Stor-Ådertjärnen, carried by ål, roach and whitefish. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Whoever fishes Stor-Ådertjärnen 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.
• Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
• Acidified water yields few, hardy species.
• Nutrient-rich lakes hold plenty of baitfish but often murky water.
