Character of the water

Stora Nycklatjärn lies in the south — a southern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. 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 (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

  • Zander: minimum size 45 cm · protected during the spawn (Apr–May).

Fishing Stora Nycklatjärn

The species list of Stora Nycklatjärn runs to 6. The predators — perch, pike and zander — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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.
  • Acidified water yields few, hardy species.
