Character of the water

Harrgrubban lies in the cold north — a northern clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 8 m and splits the lake into two worlds.

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 (17 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Harrgrubban FVOF. Day permit ~100 kr · annual permit ~500 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Harrgrubban

In the clear water pike picks its moments — wary, but relentless once committed.
roach coarse fish
typically ~18 cm · can reach 32 cm
Roach moves carefully in the clear water — small mouthfuls, many of them.
vendace whitefish

Fishing Harrgrubban

perch and pike sit at the top of the food chain in Harrgrubban, carried by roach and vendace. 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 Harrgrubban are alike.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
