Character of the water

The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Moderately deep (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

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.
