Character of the water
Södra Trollsjön lies in the south — a southern mesotrophic lake.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
A small but surprisingly deep pocket (17 m) with steep drops straight down from shore — the bottom falls away fast.

Species in Södra Trollsjön

Here perch lives on the small stuff — and rewards those who fish small and fine.
pike predatory fish

Here roach lives on the small stuff — and rewards those who fish small and fine.
Fishing Södra Trollsjön
perch and pike sit at the top of the food chain in Södra Trollsjön, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
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 Södra Trollsjön 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.
