Character of the water
Ilasjön lies in the cold north — a northern 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.
Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Ilasjön
The species list of Ilasjön runs to 3. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.
The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Ilasjön are alike.
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.
