Character of the water

Södra Grundvattssjön lies in central Sweden — a humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Moderately deep (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Södra Grundvattssjön

perch, pike and grayling sit at the top of the food chain in Södra Grundvattssjön, carried by roach, regnbåge and whitefish. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

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 Grundvattssjön are alike.

General rules of thumb for this kind of water

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
