Character of the water

Grenmyrtjärnarna lies in the cold north — a northern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 7 m and splits the lake into two worlds. Acidification has thinned life down to the hardiest few.

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

Permits & rules

Fishing permit required — Grenmyrtjärnarna FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Grenmyrtjärnarna

The species list of Grenmyrtjärnarna runs to 0. dominate here, 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 Grenmyrtjärnarna 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.
  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
  • Acidified water yields few, hardy species.
