Character of the water
Tärnsjön lies in the south — a southern humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Shallow throughout (max 2 m), with reeds and vegetation over large areas — water that warms fast in spring.

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.
