Character of the water
Tannsjön lies in central Sweden — a clear oligotrophic forest lake.
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.
A small but surprisingly deep pocket (17 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Tannsjön
perch and pike sit at the top of the food chain in Tannsjön, carried by roach. The clearer water makes the fish wary — and rewards a careful presentation.
Whoever fishes Tannsjön 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
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
