Character of the water
Hallasjön lies in the south — a southern acidified forest lake. 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 (10 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing permit required — Hallasjön FVOF. Day permit ~140 kr · annual permit ~700 kr.
- Pike: keep at most one over 75 cm per day.

Fishing Hallasjön
perch, pike and burbot sit at the top of the food chain in Hallasjön, carried by ål, bream and ruffe. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.
The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Hallasjön are alike.
General rules of thumb for this kind of water
- Acidified water yields few, hardy species.
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
