Character of the water

Holmträsken 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 6 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.

A small but surprisingly deep pocket (12 m) with steep drops straight down from shore — the bottom falls away fast.

  • Pike: keep at most one over 75 cm per day.

Fishing Holmträsken

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

Every session at Holmträsken is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

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.
