Character of the water
Oppsjön lies in the cold north — a northern nutrient-rich lowland lake.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Large and deep (24 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.
Permits & rules
Fishing permit required — Oppsjön FVOF. Day permit ~140 kr · annual permit ~700 kr.
- Pike: keep at most one over 75 cm per day.
- Handheld tackle only. Respect the protected zones at the inlets and outlets.
Species in Oppsjön
perch predatory fish
typically ~26 cm · can reach 40 cm
Perch grazes the rich water in schools — where there's one, there are more.
pike predatory fish
typically ~52 cm · can reach 69 cm
In the murky light, pike shadows the baitfish and hits in short rushes.
burbot bottom fish
typically ~33 cm · can reach 59 cm
Burbot works the bottom in the dark — smell and feel come before everything else.
roach coarse fish
typically ~21 cm · can reach 26 cm
Roach grazes the rich water in schools — where there's one, there are more.
Fishing Oppsjön
perch, pike and burbot sit at the top of the food chain in Oppsjön, carried by roach. 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 Oppsjön are alike.
General rules of thumb for this kind of water
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
