Character of the water

Trerönningen 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.

Moderately deep (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Trerönningen

perch, pike and zander sit at the top of the food chain in Trerönningen, carried by id, roach and regnbåge. 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 Trerönningen are alike.

General rules of thumb for this kind of water

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