Character of the water
Norra Dellen lies in central Sweden — a clear oligotrophic deep 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.
Large and deep (67 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

General rules of thumb for this kind of water
- Clear water makes fish light-shy — dawn, dusk and night are usually best.
- In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
