Character of the water
Trollsjön lies in central Sweden — a 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.
Shallow throughout (max 4 m), with reeds and vegetation over large areas — water that warms fast in spring.

Fishing Trollsjön
The species list of Trollsjön runs to 2. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.
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 Trollsjön are alike.
General rules of thumb for this kind of water
