Trettondetjärnen

Character of the water

Trettondetjärnen lies in central Sweden — a humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Shallow throughout (max 2 m), with reeds and vegetation over large areas — water that warms fast in spring.

Fishing Trettondetjärnen

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

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