How to fish it · for Trout
When
Through the open trout season — 15 March to 6 October. Buzzers from April through June; sedges through summer evenings; small dark flies into autumn. Caithness wind drives the fishing — settled-wind days are precious.
Where
Drift lines along the loch's broad open water. Watten is a shallow Caithness limestone-fed loch — fish on and around the weed structure.
Method
Drifted team of three on a floating line — traditional Caithness wet-fly. Soldier Palmer, Loch Ordie, Black Pennell. Drogue is essential on Watten's wide open drifts.
Kit
10 ft #6/7 boat rod, floating and slow-intermediate lines, 6 lb fluoro tippet. Drogue and a long-handled net.
The plan
Plan A
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
Plan B
If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.
Watch for
Watch for Sedge towards evening — this could be the best window of the day.
Boat — at anchor
Windy conditions suit anchoring in productive areas rather than open-water drifting.
