Character of the water
Ilasjön lies in the south — a southern 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.
Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

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