Character of the water

Nedre Koskilamm lies in central Sweden — a 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 lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

  • Pike: keep at most one over 75 cm per day.
  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.

Fishing Nedre Koskilamm

Nedre Koskilamm holds 7 species, with perch, pike and grayling at the top of the chain and roach and regnbåge schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Nedre Koskilamm regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

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.
