Character of the water
Grumlan lies in the south — a southern humic brown forest lake. 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 (16 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Grumlan
The species list of Grumlan runs to 18. The predators — perch, pike and zander — 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 Grumlan 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.
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
