In deep pools and dark water, silhouette and contrast do the work colour cannot. A fly that reads as black against depth is enough. Fish it broadside, hold the swing, let it hang at the dangle — that is when the best fish take.

How to fish it · for Sea Trout
When
Sea trout enter from April; main run summer through October. Variable-seasonal stock — fish carefully if at all. Evening into night where the AAPPMA night extension applies on the lower beats.
Where
Lower Bresle pool tails and weeded glides walked in daylight before fishing them at night. The AAPPMA Bresle manages the water; check beat boundaries before you wade in.
Method
Across-and-down on a floating line with size 10 to 12 wet — Steer's Head and soft-hackle emerger patterns suit clear chalk water; Medicine and Stoat's Tail when colour enters. Steady swing, never hurry.
Kit
10 ft #6/7, floating line, 8 lb fluoro tippet. Spare leader on a wrist spool. Permit with timbre migrateur — non-optional.
Why this works
Excellent — conditions well-balanced, with water temperature particularly in your favour.
Likely species
Stoneflies
Gammarids
