Character of the water

Mammerstjärnen lies in central Sweden — a clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Moderately deep (4 m) — shallow bays, the odd reef and a deeper channel through the middle.

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

Fishing Mammerstjärnen

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

Whoever fishes Mammerstjärnen 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
