Character of the water

Trollsvallssjön lies in central Sweden — a clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

A small but surprisingly deep pocket (14 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Trollsvallssjön

perch, pike and burbot sit at the top of the food chain in Trollsvallssjön, carried by ål, ruffe and roach. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Trollsvallssjön is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

General rules of thumb for this kind of water

Clear water makes fish light-shy — dawn, dusk and night are usually best.
